How to write information about nfc tags and 10 examples of using nfc tags that you could not even imagine

How to make it yourself?

Now I will tell you how easy and simple it is to make an nfc business card yourself.

Charging

If by now you have decided that you know everything about NFC and are tired of these dull applications. Here’s something bombshell for you.

There is an NFC Forum organization that certifies NFC. In general, each technology has such an organization, and it’s good if it is one.

And the other day they posted another update of the standard. And you know what? NFC now supports wireless charging. Yes, in fact, this is the fourth mode of operation.

How do you ask? Electromagnetic induction, remember? With the help of her.

By the way, Qi-charging works exactly on the same principle. Only there is a larger coil.

But there is one problem. The NFC coil is small, which means that the charging power is small – only 1 watt.

Is it possible to charge a smartphone at this speed? It’s not even worth trying. However, the function for this was not invented.

The main purpose is exactly the opposite – charging other devices with a smartphone. It’s like reverse charging in Galaxy and other smartphones. For example, you can power the wireless headphones themselves, and not the case from them. In fact, we have a very cheap wireless charger, which is in any smartphone and which is easy to insert into any smart device.

By the way, 1 watt is not too little. For comparison with all iPhones except 11 Pro, they put a 5-watt charger. And the power of reverse wireless charging in modern flagships fluctuates around 5 or 7 watts.

But there is one thing – this feature will not work on current models. Smartphones with such a chip will most likely begin to appear in a year and a half. So expect ads for this thing from Samsung.

Create a task

In the menu item “Set up a task”, press ” ” and activate the necessary tasks in the list of tasks. For the Work profile, select Wireless & LANs – Wi-Fi On/Off, Wireless & LANs – Mobile data on/off, and Sounds and volume – Sound profile.

Then you need to turn on Wi-Fi, turn off mobile data, and in the “Sound profile” line, select the “Vibration” item and click the “Add to task” button. After that, give a name to this task – for example, “At work” – and click “Next”. In the menu item “Configure Switch”, you can configure the sequence of tasks that the Trigger application will perform in turn after connecting a smartphone to an NFC tag.

To exit the At Work profile, select the same options again, only this time turn off Wi-Fi, turn on mobile data and deactivate Sound Profile, or set the settings as you like. Click Add to Task and give it a name, such as Home. Now it remains to click the “Finish” button.

Nfc tag instead of wi-fi password

The most obvious and simple scenario for using NFC tags immediately seemed to me to be connecting to Wi-Fi. The fact is that I often have new smartphones in my hands, and entering a long password on each of them is simply inconvenient. Now I just lean the device against the router and it magically connects to my home Wi-Fi network.

Why do we need nfc tags

The use of tags installed on the phone allows you to quickly receive any information. After the microchip has been programmed, it will be possible to perform the following actions almost instantly:

• Turn the Bluetooth connection on or off.
• Entering the specified application.
• Quickly display the desired phone number.
• Activation of mobile internet.
• Contactless payment for goods, services, etc.

Do guests want a Wi-Fi password?

Are you tired of entering a complicated Wi-Fi password to your friends every time? With NFC tags, this is not a hindrance. To do this, just stick the tag in a place convenient for you, and if your colleagues ask for Internet access, you will direct them to the tag.

Write Protect

After all the above steps, you can open the setting menu at the top of the screen to enable another write protection on the NFC tag, but in this case, the information on the sticker cannot be overwritten. Problems with writing information to an NFC tag may also arise if the Trigger application must include a profile that has already been pre-programmed on the sticker.

Where to buy NFC tags

NFC tags are readily available from your favorite online NFC store. You can purchase them from their respective dealers or online retailers such as Amazon. If you need wholesale NFC tags, please contact our factory.

Before you buy an NFC tag, make sure you consider all the factors we have detailed here to meet your needs without any disappointment.

Programming tags is easy. Both a child and an elderly person can cope with this. To set up, you need a mobile with NFS, tags and a special application (such as NFC Tools or some other similar one).

Let’s try to figure it out using the example of recording a phone number:

• Enable NFC in device settings.
• Go to the free NFS tag programming app and click “create”.
• Select the entry type “phone number”.
• Enter the corresponding set of numbers.
• Click on “done”.
• Bring the NSF tag to the gadget.

A beep will sound that the mark has been created successfully.

You can check the functionality of the created NFS tag right away. To do this, just bring it to the back of the smartphone. After a second, the programmed phone number will be displayed on the screen.

How to create an electronic business card?

We will create an electronic business card that can be programmed in an NFC tag in a special Jusl service – it works in a Telegram bot, and everything is much simpler there.

Save profile and customize sticker

Save the profile on the NFC sticker by placing your smartphone on the back of it, or simply place your mobile device on it. To exchange data, the distance between the smartphone and the tag should be several millimeters, so I recommend that you think over the location of the NFC tag in advance.

After successful synchronization with the NFC tag, the smartphone will vibrate and the message “Tag successfully installed” will appear. After that, click the “Finish” button – you will find yourself in the main menu of the application. Now the NFC sticker is ready to use and can turn profiles on and off one by one.

Nfc tag instead of wi-fi password

The simplest and most popular use of NFC is to quickly connect your smartphone to a Wi-Fi network. This is especially true for those who constantly deal with new gadgets. If a rather complex and long password is set on the router, then entering it manually each time will not be very convenient.

However, after programming certain actions, this procedure is simplified. It is enough to bring the smartphone close to the router, and the connection will be established immediately. Such a scheme is ideal in public places where visitors are provided with the opportunity to connect to wireless Internet.

How to setup nfc tag on android

Solving the problem of how to program NFC tags on an Android smartphone is not particularly difficult. All actions are performed in a certain sequence:

How to write a bank card to an NFC tag

The easiest way to make a contactless card is to bind it to a smartphone that has an NFS chip. You can use one of the services:

• Google Pay (on Android devices);
• Apple Pay (for iphone);
• Samsung Pay (on Samsung gadgets).

To bind should:

• Click on add card.
• Enter payment method data or scan it.
• Accept all conditions.
• Enter SMS code.

After the correct linking, it will be possible to successfully carry out contactless payments in various outlets.

Is it possible to encrypt data on the nfc chip

Special encryption functions are not directly supported by NFS standards. However, this hurdle can be bypassed with the MineType multi-purpose extension. On its basis, data is created that is first encrypted and then read using the decryption key. For all other applications, such entries will not be available. All actions are performed automatically.

Programming

In order for the device to work and be useful, it is necessary to install additional applications that are task managers for NFC tags. The operation setting is carried out according to the following principle:

How to program nfc tag

Before using an NFC tag, it must be written to the phone. This will require the installation of a special application with which the smartphone can read the necessary data.

Settings will only be possible if certain conditions are met:

• Presence of a smartphone or tablet with a pre-installed NFC module.
• Application for working with tags.
• A sticker placed in the right place.

Types of tags for payment

These microchips are of two types: with limited compatibility and universal.

The second one is compatible with all operating systems and gadget models.

There are also 4 types of tags. Their differences are in the amount of memory and data transfer speed.

Attention! On NFS tags of the 1st and 2nd type, you can write information and then erase it – they are rewritable. Such manipulations can be carried out up to 100,000 times. Types 3 and 4 are not reprogrammable.

Is it possible to overwrite information on the nfc tag

When purchasing tags for the phone, many users are interested in their functionality. First of all, it is the ability to rewrite, when existing data can be deleted, and new information is introduced in their place.

This operation can be performed almost unlimited number of times until the mark is locked and overwriting becomes impossible. The lock cannot be revoked, so all data stored on the microchip remains permanent and read-only.

nfc activation

If there is no icon of an active NFC module on the notification panel of your smartphone, then you can enable it using the menu items “Settings – Wireless networks – Enable NFC” or use a special widget. Then install the free Trigger app from the Play Store.

Distinctive features of the Trigger utility are an intuitive interface and a large number of options for automating the operation of a mobile device. After installing Trigger, open the application and go to the “My Tasks” menu item.

Publishing a business card

In general, the business card is ready. To check if we made any mistakes, click on “Preview” – check. But even after publication, you can always change everything and add other features.

After checking, if everything is in order, press the button.

The bot will send us a link to our electronic business card – we must program this link in the NFC tag.

Conclusion

Making an nfc electronic business card yourself is not so difficult.

For this you need:

• Create an electronic business card in advance in a special service;
• Buy an nfc chip with an anti-metal surface, come up with a business card design and fill the nfc chip with polymer resin in printing;
• Program a link to an electronic business card in an NFC tag through the “NFC Tolls” application.

How NFC tags work

NFC tags have the same working rationale as RFID tags. They use radio waves to transmit information from one device (tag) to another (reader). These tags are also called SMART tags or INFO tags because they are primarily used to convey information in an automatic format.

It does not require pairing, which ensures an easy application process. All you have to do is bring two NFC-enabled devices closer (about 4 inches). They will connect automatically.

Once you’re connected, you’ll tap on the files you want to share and select NFC Sharing. This way you can share many files at the same time!

Compared with Bluetooth, NFC file sharing is more than ten times faster and more convenient.

Tag in the car

In addition to the premises, the tag is quite convenient to use in your car. To do this, you can stick it, for example, on a torpedo, and in the morning, when you still haven’t recovered from sleep, you have absolutely no desire to turn on GPS, mobile data transfer, open a navigator application, an NFC tag will come to your aid: bring smartphone and the problem is solved. Every morning you will save 5 to 10 minutes of your time.

How to choose NFC Tag chips

The NFC chip you choose will depend on what you need. In addition to the types above, also consider the following NTAG features before choosing the perfect NFC tag:

• STAG 213. These NFC chips are easy to use and reliable. They will serve most of your data transfer needs.
• NTAG 215. These NFC chips come with 540 bytes of memory. These are the perfect chips if you want to make your Nintendo Amiibo your home. Some amiibo figures you can make with these tags include Legend of Zelda and Breath of the Wild.
• NTAG 216. These are high-quality standard chips that are ideal for NFC business cards. They can store a lot of data and information.
• Mifare Ultralight. These are affordable chips that store simple data like URLs and identification numbers. They are ideal for large-scale projects that require a small amount of data.

Always remember that choosing the wrong type of NFC can be wasteful. For example, if you want to make amiibos at home only sttk 215 will work. If you buy any other type of tag, it will be a waste.

Types of NFC tags and their compatibility

According to the NFC forum specification, there are five types of tags. Consider the main characteristics of each of them:

You can also program the tag using your iPhone through the “Teams” application on the phone itself. To do this, after writing the command, select the NFC item at the bottom of the screen and click on the NFC line again. After that, the scanner will start, and you just have to bring the phone to the label and sign it in the application.

If your phone supports NFC technology, the easiest way is to link the card to your smartphone using the mobile payment service: Google Pay (on Android devices), Apple Pay (for iOS gadgets), Samsung Pay (on Samsung smartphones). It can also be third-party services of various payment systems or banks.

The general procedure for linking a card to a mobile payment service is as follows:

• Enter these details of the payment method or scan it using the camera or NFC.
• Accept all the conditions and confirm the binding with a verification code that will be sent via SMS.

Different services may have their own nuances at the stage of adding a card, but the general scheme is the same for all. After linking the plastic to the phone, you can make contactless payments for goods without using a card. It will be enough to bring a smartphone to the terminal.

If your phone is not equipped with contactless payment technology, many people recommend using NFC tags to record card details and then use the tag when paying for goods in stores. This is an erroneous recommendation, because neither the phone nor the tag can copy a bank card.

When reading tags with appropriate applications (for example, NFC Tools), you can attach plastic to the back cover of the device and see open information about the card, but when you try to write information to the media in the form of a tag, the application will report an error because the card is protected.

Therefore, emulating a plastic card using an NFC tag is not possible.

How to check if your smartphone supports NFC

If you are wondering how to check if your smartphone supports NFC, follow these simple steps:

• Open the “Settings” section on your smartphone.
• Go to Wireless & Networks.
• Click More
• If your phone supports NFC, you will see the “More” option.

Alternatively, you can open the “settings section” and search for NFC in the search bar. If it returns NFC application results, then your phone supports NFC.

You can transfer a bank card to a contactless version by linking it to a mobile device equipped with an NFC chip. The following services are most suitable for this purpose:

• Google Pay. Enables the operation of android nfc applications used in smartphones.
• Apple Pay. For use with iPhones only.
• Samsung Pay. A branded application that works exclusively with Samsung gadgets.

The solution of the problem of how to write a bank card on a label is performed in the following sequence:

• Sign in to the contactless payment app.
• Click on the item to add a card.
• Enter card details or scan it.
• Agree to all terms.
• Enter the code received in SMS.

If the binding is done correctly, you can pay using your mobile device in all outlets where contactless payment is possible.

NFS tag reading distance

The average distance that provides stable non-contact communication is 4-5 cm. For the most advanced devices, this figure reaches 10 cm. The effective distance may vary, depending on certain factors affecting performance:

• NFS reader of different capacity is installed in each phone.
• The size and configuration of the tags must be considered before using contactless communications.
• Environment. The presence of metal objects creates a serious obstacle to a contactless connection.
• Microchip model. The performance of bracelets and rings is much higher than that of ordinary stickers.

Usage examples

How is NSF tag used? They are installed in various places in order to convey certain information.

NFS tags can be used for:

• Conducting payment transactions. In this case, the NFS chip must be on the card, in the phone or other gadget, and in the terminal.
• Turning on a tape recorder, navigator, Wi-Fi, bluetooth, etc. Programming nfc tags in cars is especially relevant.
• Opening and closing windows, doors, locks in houses.
• Distribution of phone numbers or other contact details, important information. You can make a recording that will be shared with others. Many create voice messages that are played after contact with the NFS tag.
• Control of appliances in the apartment (washing machine, TV, etc.).
• Enable/disable flight mode, alarm clock, notifications.
• Data synchronization.
• Cargo tracking.
• Passes to educational institutions, cinemas, clubs, etc.

These are not all examples of using NFC tags. The list goes on and on. Knowing the essence of their work and performing the correct settings, it will not be difficult to program your own phone, household appliances or car.

Start your laptop with the label

You can make your laptop turn on when there is wireless network activity, bring your smartphone and your laptop is turned on.

Automatic launch of the navigator in the car

Of course, this operation can be performed manually, however, sometimes you want to feel all the delights of technical progress for yourself. It seems to be a trifle, but when the label installed in the smartphone holder gives the command to turn on the navigator, this makes an indelible impression, especially on passengers.

Features and Benefits

The use of NFC tags helps to solve problems of both a domestic nature and business or marketing. The advantages of NFC tags include:

• connection speed – a tenth of a second is required to establish contact;
• security – data transmission channels are encrypted and protected;
• convenience – the use of NFC tags automates and simplifies the performance of various tasks: electronic payment, connection to a device or data exchange;
• compatibility – the technology supports many RFID systems and can work even if the smartphone is turned off;
• widespread – chips and tags can be installed on a variety of devices;
• Availability – tags are inexpensive and sold on many online and offline marketplaces.

Examples of using NFC tags

“NFC technology acts as a welcome handshake and allows you to bypass connection security checks. For a person, it does not pose a threat: data transmission takes place at a safe frequency of 13.56 MHz.

Using the phone’s NFC chip for contactless payment for goods has become commonplace, but this is not the only use case for technology that brings convenience to life. Consider what familiar processes can be automated and simplified using an NFC tag and a smartphone.

This scenario is suitable for catering establishments, beauty salons, shopping malls and other public places. Usually, each new smartphone connects to the network manually by entering a password, which is not always convenient.

Having installed an NFC tag on the router, it is enough to bring the device to it so that it connects to the wireless network, bypassing the usual connection setup procedure.

Label for quick activation of the alarm clock and night mode

A useful recommendation for those who do not want to set the alarm every day at the same time or are afraid to forget about it at some point.

The tag can be programmed to set an alarm and automatically activate night mode, and then place it at the head of the bed or on the bedside table. Now, every time you put your phone back before bed, the tag will give a command, and the device will perform simple actions for you.

Tip for drivers: The tag can be placed on the phone holder in the car. After installing the device in it, the navigator will turn on automatically. Additionally, you can program the tag to connect your smartphone to the car’s Bluetooth system.

Launch PC

To do this, you need to set up Wake on LAN on your computer. After that, you can use the NFC tag to turn on the PC from anywhere in your apartment. The method will be convenient for those who completely turn off the computer, and do not start hibernation. It will also help save time: the device can be started in parallel with how you prepare breakfast or perform other morning tasks.

Wi-Fi for guests

In this scenario, a label with a password recorded through the InstaWi-Fi application is glued to the router. Visitors will only need to bring their smartphone with NFC to the tag and freely use the wireless network. The method is suitable for those who like to receive guests, but are tired of giving the Wi-Fi password to new people every time.

Timer

When playing sports, as well as while cooking, it is often necessary to note the time. If you program an NFC tag to start a timer, this process can also be automated by simply bringing the device close to the tag. The main thing is to place it in a convenient place.

Reason to leave the premises

If you find yourself in a situation where you need to go away without attracting unwanted attention (for example, out of need, to a smoking room, or to escape from an annoying company), program a label to call you through the IFTTT application. A few seconds after you bring your smartphone to the tag, the phone will receive a call, allowing you to safely leave the premises without arousing suspicion.

Music

This method will help you quickly connect to a speaker or other speaker system. It is enough to place a label programmed to turn on Bluetooth on a speaker, headphones or player. After bringing the smartphone to the tag, the phone will activate the function, and the connection to the device will occur automatically.

Business cards

Quick Launch

After analyzing some moments in life, we can notice that visiting certain places or using certain things is associated with the launch of the corresponding application. By placing a programmed label on an object or in a room, you can automate this action. For example, launching a navigator with a tag on a bike, a calorie counting app in the kitchen, or notes with a shopping list on a shopper.

Making a business card

Add a title (who owns the business card/company name). Click and enter a name.

Add minimal information about the owner. Let’s press “. We write briefly about ourselves or our activities.

Let’s add a logo (or a personal photo). To do this, I will click and send my photo.

In order to change the background on the e-business card page, colors and fonts, use the corresponding buttons. And with the help of a button, you can also add a feedback form to your business card – then people who have scanned your business card will be able to leave you a request directly in the bot.

In general, the business card is ready. To check if we made any mistakes, click on – check. But even after publication, you can always change everything and add other features.

How to use tags

We have figured out the principle of the labels, but where is it convenient to place them? Advanced youth use microchips to make everyday tasks easier. For example:

• Wi-Fi distribution;
• enable night mode;
• payment for purchases;
• equipment management.

About apple

What if you have an iPhone? Everyone thinks that NFC access is disabled on the iPhone, but this is not the case. Starting with iOS 11, that is, from 2022, Apple opened access for developers. And there are already a lot of applications the same as on Android. For example, NFC Tools.

True, there are restrictions there: transport and bank cards, for example, are not scanned. We need special labels, which we have already talked about.

What to do? iOS 13 introduces the Commands (Siri) feature. And now she just has access to any NFC tags. So here you can set up the launch of music on the Troika card. Or turn on a smart light bulb. Or a bunch of other things. Teams are a real bombshell. I don’t understand why Android still doesn’t have this.

Why do we need nfc tags?

When Philips, Sony and Nokia created their NFC forum in 2004, this technology was known only among enthusiastic techies. The three whales of the electronics industry set themselves the goal of researching, promoting, and of course, commercial profit from the introduction of new contactless data transmission technology. But they did not achieve much progress – all their achievements seemed to be nothing more than a toy.

For reference: NFC (from the English. Near Field Communication) is a technology for transmitting data at a very close distance, about 5-10 cm. It is a kind of RFID technology – radio frequency identification.

In 2022, Google joins them and that’s when the real flowering of technology begins, because NFC chips began to be supplied with most Android smartphones. Users immediately appreciated the convenience and security of Google Pay – no need to enter boring passwords for everyone; card reading was fast and error-free. And most importantly, there was no need to get a bank card at all – all data is stored in the smartphone’s memory.

But this was only the beginning, because the new technology allows the exchange of data generated on the fly, unlike RFID, where data is flashed once and forever.

“NFC is just a hello handshake,” says Ray Hartjen of Sony – “Streaming is already happening via Bluetooth.” And NFC technologies allow you to do without the necessary security check of the connection. The technology itself is completely safe for humans, as it uses a safe frequency of 13.56 MHz. And because of the short range, the level of magnetic radiation is very small.

Night mode

Imagine the situation: in the evening, going to bed, you turn off Wi-Fi, Bluetooth, mobile data transmission, turn on silent mode; in the morning, waking up, you do all the same manipulations, but in reverse order. Now imagine that you have an NFC tag: you put or stick it next to the bed, and that’s it – the problem is solved – now, if you decide to go to bed, just bring your device to the tag, and you’re done.

Adding contact information and vcard to the business card

1. Go to the bot and click on, then on Then we send our first contact – this can be a link to a source or a phone number. I will send a phone number.

To edit and add link buttons and other contact information to a digital business card, as well as enable the vCard and QR-vCard function (these are things that automatically save your contacts to the client’s phone), click on

Accordingly, to add a vCard, I will click on , and to add buttons-links to other sources, I will use the function I will send links to my page on VK, YouTube channel, to my blog, etc.

*When you start adding buttons, the bot will prompt you to choose a tariff, for an nfc business card, you should either choose the “Forever” tariff or pay for a business card for a year.

3. To edit the name and description of each added link button, you need to click on the added contact in the same menu and use the and functions

The developers did not provide the encryption function for Rfid tags. This can only be done by creating Mime type entries. In this case, the information will be encrypted, and the key will only be in the reader program.

Why do I need an NFC tag

The scope of labels is really very wide. The gadget in the form of a keychain can serve as a personal business card. You can also hang the keychain on a nightlight and when you bring your smartphone to the label, the Do Not Disturb mode will be activated. You can put a key fob near your workspace and when you sit down to work, the label will automatically start synchronizing data between devices.

Bedside NFC tag.

In addition to key rings, there are also sticker tags. They, for example, can be attached to the cover of your computer. In addition, after purchasing the tag, you will have a great opportunity to quickly share your Wi-Fi password with guests. I also liked the option of a wedding or birthday invitation using this technology. In a word, there are a lot of options for the development of events. Anyone who decides to purchase this device will find a worthy use for it.

NFC tag reading distance

NFC tag refers to short range tags. The distance between the tag and the device to establish a connection cannot exceed 10 cm. Sometimes this is considered a disadvantage of the technology, but this feature has advantages: NFC consumes little energy, and close contact prevents the interception of personal data.

How to program an NFC tag

Now that everything is ready, let’s program the nfc tag.

Such tags are placed in the phone to speed up the receipt of any information. After programming the microchip, it will be possible in a second:

• enable or disable bluetooth;
• display the desired phone number on the screen;
• activate mobile internet;
• pay for a product or service, etc.

Note! The cost of NFC tags is cheap – from 20 rubles.

How to set up nfc profile

With the NFC sticker, you can set up different profiles for the convenience of working with your mobile device depending on your location.

NFC tag components

An NFC tag consists of three main components: a chip, a substrate, and an antenna. Here is a breakdown of the functions of each of the components:

• NFC chip. This microchip is quite small (it’s the smallest part of the NFC tag). It contains a memory that stores information. It can store a wide range of data such as images, email addresses, phone numbers, and website links. This data is stored in NDEF (NFC Data Interchange Format) format for ease of transfer.
• NFC antenna. This is the section of the NFC tag that detects or emits radio waves. It is shaped like a coil/loop of wire that is engraved in a strategic place on the NFC tag. If this part is defective, communication will not occur because smartphones will not send and receive signals.
• Substrate. This is the part that holds the NFC antenna and NFC chip together. This is the largest part of the NFC tag, and it can be in the form of plastic or sticky materials, depending on the type of NFC tag.

NFC tags come in many forms, including NFC stickers, NFC tabs, NFC labels, and NFC discs. This diversity allows you to choose the format that best suits your needs. For example, NFC stickers are perfect for sticking to your desktop to automate tasks.

In addition, you can purchase customized NFC tags. For example, you can purchase NFC key chains, bracelets, and mats.

Scenarios for using nfc tags

There are quite a lot of options for using tags in practice, and all of them, to one degree or another, facilitate the use of certain devices, significantly speed up the implementation of regular routine actions. Below are the areas where the NFC function is used most often.

Using NFC tags

NFC tags have many smart apps to make your life interesting. Some of the unique NFC tag apps include:

Using an NFC chip to invite friends and family to a wedding will leave an indelible mark. These cards have an NFC chip embedded with a unique ID for each invitee.

This app helps improve safety and efficiency for countries. Passports have an embedded NFC label that stores the personal data of the passport holder.

When using these cards, countries can apply anti-counterfeiting features that guarantee high security. It can also help in tracking the time when a visitor visits or leaves any country. What’s more, the tags can be customized to suit your needs.

Simple paper NFC tags can store unique data such as addresses, names, and unique identifiers that help with access control. Tags can be used to track the movement of a specific person in and out of any room.

In addition, these tags can be made into key chains, bracelets, NFC cards, or any other shape for ease of use. Thus, you will always be sure of quick identification of visitors and employees, which will increase security.

You can use NFC tags to automate your home. This allows you to effortlessly perform actions such as opening doors, sharing Wi-Fi passwords, syncing music, and remote desktop launch.

For this, you can purchase a blank NFC tag and use NFC recording apps to write and store your desired information on the tags.

These NFC-enabled posters help you quickly share information. The poster has an embedded NFC label that contains a URL, video, image, or any other information.

When an NFC-enabled smartphone approaches the poster, the user gets all the information embedded in the tag. These tags can be customized to contain any data, making it easier to advertise.

Buy nfc chip

The first thing to start with is to purchase an nfc chip – a small microcircuit into which we will encode an electronic business card.

The cheapest way is to buy it, for example, on Aliexpress. It will cost you about 30 rubles apiece. Or you can buy it at a local radio engineering shop – it will be more expensive there (from 100-200 rubles apiece), but quickly. The one you purchase must be with an anti-metal surface, otherwise your business card that you make will be read worse or not at all due to extraneous interference.

For a business card, buy an NFC chip coated with an anti-metal layer, otherwise the business card does not count

We come up with the design of an nfc business card and send everything to the printing industry

It’s better to make a business card out of resin – it’s more beautiful and durable. This is what an electronic business card made of polymer resin looks like:

electronic nfc polymer resin business card

Then it was necessary to find the right software to write down the maximum possible contact information on the “magic business card”. I tried every possible set of

and settled on a program from the chip manufacturer (NXP) –

In addition to reading and writing, it can temporarily or completely make a read-only label, copy labels, read full data from the chip, and so on. In addition, it records the maximum possible business card, and not just pre-recorded data types.

What kind of information, in principle, can be written on a label?

Pretty good list. In other NFC recording applications, there were also exotic options, for example, recording data for accessing a Wi-Fi network or automatically sending SMS to a specific number with text, but for ordinary situations such a set is enough.

We select a business card and select our contact from the address book (after creating it), which may include first name, last name, various phones, email addresses, websites, physical address, date of birth, notes. In theory, a photograph is also possible, but, of course, it will not fit in a kilobyte business card.

Save the data to the label plus add the launch of the “Contacts” application

Now if you get to a conference where there will be not only iOS devices (for example, I used the “magic business card” on Google IO), you can easily let you attach your “added business card” to the device and immediately save your contact to the visitor’s address book. W OW effect is guaranteed. And given the likely support for NFC in the new iPhone, the area of ​​u200bu200buse is expanding significantly.

By the way, there is another way to use NFC tags, including used ones (for example, old metro maps): write down the sequence of actions when a tag with this ID is found nearby. The leader in this area is the Trigger app (formerly NFC Task Launcher, which added support for Wi-Fi, Bluetooth, coordinates, time, battery percentage triggers).

You can, for example, put a tag at home, in the car and at work to connect/disable wi-fi, data transfer, bluetooth, silent mode, send messages, launch navigation or work applications, start playing music, etc. A very cool way to automate the usual actions. You can read more in the article on Habré

As a result, with the help of a physical tag, you can add charm to your business card and easily “register” in your partner’s notebook using “NFC-magic”.

Before buying this or that type of tag, you need to make sure that it will be compatible with the main device – a smartphone, will last for a long time and will not malfunction. The NFC tag type can be universal or limited compatibility.

Tag models are shown in the table.

How to program nfc tags

Read information from wireless media and personally pack text, tags, URLs or contact information into NFC tags using special software tools provided for iOS and Android operating systems in the App Store and Google Play digital stores, respectively. After downloading the software, it remains to sort out the details:

With iOS, the situation is similar: “Simply NFC” (and analogues) – simplify the use of NFC tags and add transparency to each action.

At the time of reading, the tools are able to: recognize text, links, vCard entries (kind of contact lists), SMS and E-mail content, Wi-Fi network configuration, and also specific thematic actions. In the iOS environment, auto-playing commands for HomeKit (turn on music, change lights, check the weather) are popular. For Android – setting up sound profiles, starting timers, preparing text through a speech synthesizer.

• Stickers have a shelf life of up to 10 years.
• NFC chips can even survive being submerged in water (with proper design).
• Do not lose valuable qualities at temperatures from -25 to 85 degrees.
• Operating frequency – 13.56 MHz.
• Memory capacity – depends on the specific manufacturer, but usually approaches 888 bytes.
• Reading speed – 106 Kbps.
• Often confused with Wi-Fi, but this module is passive.

Compared to its closest analogue, Bluetooth wireless technology, NFC noticeably loses in speed, but does not suggest worrying about pre-configuring the connection. The reading procedure is lightning fast, one has only to bring the mobile equipment to a suitable chip.

All tags are manufactured according to the world standard ISO 14443. Conventionally, they are divided into 4 types, depending on their characteristics. They are determined by the amount of data and the speed of their transfer. At first glance, these parameters may seem insufficient compared to other technologies.

All microchips can be written and rewritten many times without any limitation. Their classification is as follows:

• Types 1 and 2 are equipped with 48 bytes and 2 kb memory respectively. The signal is transmitted at a speed of 106 kbps.
• Type 3: Non-rewritable label. However, they are capable of solving more complex tasks, and the transfer rate is much higher – 106 kbps.
• Type 4. The most powerful and productive. Internal memory reaches 32 kb, and information can be transferred at a speed of 106-424 kbps.

Usually, short-range communication works at a distance of 10 cm. But the distance also depends on various factors, for example:

• type of NFS reader;
• the shape and size of the label;
• environment (metal objects become an obstacle to contactless communication);
• models (bracelets and rings work at a greater distance than stickers).

Using a Bluetooth headset is now easier

If you are a fan of listening to music in a Bluetooth headset, then the tags will make your life much easier. You just need to stick a label to the headset, and if you put on the earphone, Wi-Fi, Bluetooth and the music application will automatically turn on in your smartphone.

Notes in Evernote

With the help of tags, you can launch not only the Evernote application, but also open certain notes in it. This will help you if, for example, you decide to cook a dish, but forgot how to cook it, in this case, bring the device to the mark – and you have your recipe in front of you. Note that for the label to work, it needs to be programmed, applications in the Play Market will help you do this, and there are a lot of instructions on the Internet. Therefore, if you still think that NFC is superfluous, you should try it yourself.

Where to buy nfc tags and how much they cost

The widest range of tags is presented on the Aliexpress site. Most of all here are simple stickers sold in sets of 10 pieces. On average, one such set costs 220 rubles.

All manufacturers produce tags according to the same protocol, so the work is carried out according to the same schemes. The main differences between the chips are in their configuration and printed pattern. Higher quality labels use thicker paper. As an example, there are sets from AnyNFC, consisting of 6 stickers priced from 312 rubles.

For unusual or specific teams, inexpensive stickers without pictures are provided, costing 83 rubles for 6 pieces. Only a logo is applied to them, displaying the wireless technology of the NFS. After installation and programming, they are applied with their own drawings created on a computer and printed on a printer.

How to setup nfc tag on iphone

iPhone gadget settings are considered more complex. Full use of NFC tags is available only for devices of the following series: XR, XS, 11, 11 Pro, SE 2020 release. These iPhones perform all set actions completely offline. Earlier devices – 7, 8 and X models are deprived of this function and the scanner has to be opened manually each time.

The gadgets of the 6, 6S and SE series of 2022 are in the most disadvantageous situation. Reading tags is not available to them, despite the NFC microchip installed in them.

NFC Tools is considered the most convenient and popular program for iPhones. It is very well suited for programming and subsequent reading of labels. Settings and actions are carried out in the same way as on a smartphone, with the exception of those models where the application is opened manually.

The iOS operating system has a set of standard commands, but, according to many users, they are not entirely clear when setting up. Therefore, most iPhone owners prefer to install third-party applications.

How it works

In short, just like passive RFID chips, NFC uses:

• antenna;
• safety block.

The antenna transmits information between the tag and the reader. Also, with the help of the antenna, the microchips inside the NFC tag are powered. The principle of electromagnetic induction is used – when reading information, a magnetic field is generated in the smartphone’s antenna.

The security block consists of a set of chips, some of which store user data, and the other deals with signal decoding, reading and writing information. The security block can be either a physical device – specific chips on an NFC tag, or emulated by software, as is the case with PDA – smartphones, PDAs, smart watches and other portable devices.

In general, the device resembles a microcomputer – it even has its own processor and RAM. Due to its design, the NFC tag does not require power, is cheap and allows you to reprogram yourself for different tasks. But there is a limitation – to organize data exchange, you need at least one active NFC controller.

If the tag is not blocked for rewriting, then the information can be erased and recorded again as much as necessary. Blocking will lead to the fact that the data of the NFS tag will be saved forever, only their reading will be available.
