Many mobile phone users confuse QR codes and barcodes. Visually, they are similar, but the latter have small squares instead of stripes.

QR code is an abbreviation. The full name stands for “Quick response”. “Quick Response” is translated from English into Russian. This is a system that has great functionality:

• placement of a large amount of data due to the ability to read information not only from left to right (like a barcode), but also in any other directions;
• tracking and anti-counterfeiting;
• making payments;
• moving the required data in an instant;
• easy reading with a scanner that does not need to be set at a certain angle.

Initially, the QR code system was invented by the Japanese, who implemented it for Toyota. She helped to quickly find out the location of the car, its description.

Latin, Japanese characters and numbers were encoded in the system. It took about a year, but it was possible to put about 7,000 different characters into the code, which is much more than the data for the barcode.

Scanning coded information with a smartphone

The QR system was first tested on mobile devices in 2002. Smartphones were produced that already had a built-in scanner. Since the program is developing more and more every day, it is used by almost every person, it is important to know how to use a QR code on a smartphone.

The system of squares includes 6 components.

• Retreat. This is a colorless frame located along the edge. It is needed to localize information in the center so that the scanner can read it without problems. External foreign elements cannot interfere.
• Search pattern. These are 3 black squares that tell the reader the location of the boundaries. The pattern creates a landmark.
• Leveling pattern. A small square located in the lower right corner. With its help, the device will be able to read the data if they are located obliquely or upside down.
• Sync band. This is the line next to the search pattern. With the help of the strip, you can scan each square individually or a damaged QR code.
• Version. It includes a small field indicating the version of the QR code.
• Data cells. The main content of the information. This may include a link to a website, purchase number, and other data.

The action of the program is carried out only in the case when 6 departments are gathered together at once.

Example of using a QR code to connect to WhatsApp

QR codes have become widespread in various fields of activity, but most users still ignore their operation or simply do not know what to do with them.

In this article, you will learn how to scan a QR code on an Android smartphone, what software you may need for this, what may be fraught with a mysterious graphic style, and much more. Armed with the knowledge gained, you will be able to put into practice this popular and useful feature.

What is a QR code and why was it invented

Such a phenomenon as a QR code first appeared in Japan. Initially, it was created for the needs of the automotive industry, but later found its application in other areas of human life.

A QR code is a barcode that can contain various information, including a description of a product / service in the form of text, a link to an Internet site, store location coordinates, contact details, payment details, and much more.

Modern smartphones can easily read the information contained in a QR code using the device’s camera and special programs.

How to read a QR code

Action algorithm for scanning and reading data:

• Step 1 – Open the installed QR code reader on your mobile phone;
• Step 2 – Point the smartphone camera at the barcode so that it completely enters the designated frames;
• Step 3 – If the code was not read automatically, then press the camera shutter key.

As a result of these simple procedures, the smartphone should read the QR code and show what exactly is encrypted in it, or offer you to follow a hidden link.

What apps to use to read the QR code

A huge number of different programs for reading QR codes have been created for smartphones based on the Android operating system. The principle of operation of applications is almost identical, so their choice depends on the taste preferences of the user.

Let’s take a look at the most popular mobile app options, including “Lightning QR Scanner”, “QR Barcode Scanner” by GeeksLab and “QR Code & Barcode Scanner” by Green Apple Studio.

“Lightning QR Scanner” – a simple and understandable program for reading QR codes with an interface in Russian. Users note the speed and reliability of work, as well as the absence of overly intrusive advertising. To work correctly, the application only needs permission to use the camera. One of the features of Lightning is the presence of a history of scans, so you can use a previously scanned link, even if the code is no longer at hand. The received links can be sent via popular instant messengers. To read the code in the dark right in the program, you can turn on the flashlight.

If you need to not only read QR codes, but also create them yourself, then you should take a closer look at the application from Geeks Lab. The created barcode can be sent to friends on social networks and popular instant messengers.

Users praise the program for its speed, but note that the application does not read small format QR codes if macro photography is not supported on the smartphone.

The most popular app for reading QR codes on Android is “QR Code & Barcode Scanner”. It can also generate codes, while this program has even more possibilities for encrypting information. With it, you can “hide”:

• Events;

Behind each such graphic key, important, useful and simply interesting information can be hidden. That is why a convenient program for decoding QR codes should be on every smartphone. Moreover, you won’t have to pay even for the most worthy options.

Kaspersky QR Scanner is a branded scanner for QR codes from Kaspersky Lab.

If there is a link that leads to a potentially dangerous site, the application will immediately report this and advise you not to go to it. The same applies to any malicious content for the Android operating system, if the attackers decide to sew it into a QR code.

How to read a QR code from the screen of your smartphone on Android and iOS

This can be done even without third-party applications.

It is not difficult to scan a QR code on a computer screen with a smartphone camera, but what if you see the code on a smartphone and cannot read it with another device? There are several solutions, and they are quite simple, although not everyone knows about them.

How to read a QR code on the screen of an Android smartphone

First you need to save the QR code on your smartphone as an image. For example, you can just take a screenshot of the screen with it. On Android, this is usually done by pressing the power and volume down keys at the same time. The image can then be scanned.

Via Google Photos

If you use “Google Photos”, then just open the image with the code and click “Lens”.

A link will appear over the picture, which was encrypted. You can navigate to it by clicking on it.

Via preinstalled apps

Many smartphones have a pre-installed application for reading QR and barcodes. For example, on Xiaomi and Poco it is called “Scanner”.

The application can read both through the camera and from the image saved on the device – just select a picture from memory by clicking on the gallery icon.

Through third party apps

Many third-party scanners that can be installed from the Play Store work in the same way. An example is below.

How to read QR code on iPhone screen

On Apple devices, the principle is the same: first you need to save the QR code. There are several ways to take a screenshot:

• on an iPhone with Face ID, press the side key and the volume up button at the same time;
• on an iPhone with Touch ID, the Home button and side key.

Further, the code can be read in two ways.

Via “Photo”

The standard Photos app allows you to read a QR code from an image if Text Scanner is enabled in iPhone settings. It’s in the “Language and Region” section.

After activating it, a swipe icon will appear on the picture with the code in the Photos application. Click on it and you will be able to follow the link in Safari.

Here we also note that the reading icon sometimes appears even without saving the code to the device, for example, when it is opened in the messenger chat – this is even more convenient.

As with Android, there are quite a few third-party scanners in the App Store that can work with images. In them, just select a picture with a code from the gadget’s memory and click on the link.

Features of how to check QUAR code on Samsung phone

To view the value of QUAR on a Samsung phone, it is enough to use the standard application, which is already included in the functions. Click on the icon located in the quick menu (opens when you swipe down on the display). When hovering, information is read automatically. If it was not possible to do this on Samsung, use another option:

• opening the chamber;
• switch to the “More settings” icon;
• search and connect the scanner.

This mode is also performed automatically. The user is presented with a link to a web page that must be clicked on to view the information.

Pay by QR code via Samsung

Checking on other phones

The scanning system is also used on other Android phones.

The factory settings of the smartphone contain a program for decrypting information. To find it, go to the “Tools” section. There they look for the folder “Additional menu”.

Select an application for scanning QR codes. As soon as it starts, you can point the camera at the squares to decrypt. The user will receive a link that they need to follow to view the encoded information.

In the Android operating system of a Huawei smartphone, the scanner is included in the functions automatically. Unlike other devices, it can be used even on a locked screen.

It is enough to make no more than 3 clicks to decrypt. Previously, they go to the quick search menu, where they find the scanner icon. Point the camera at the squares to get the result.

The connection is very fast, within 1-2 seconds. The app on both phones should show the website you want to go to. Users of these smartphones do not need to download third-party programs that contain a lot of ads. The standard application is fast, easy to use, versatile for various types of encrypted information.

How to read QR code from screenshot on iPhone

One convenient and reliable way to scan QR codes from screenshots on iPhone is to use the Google app (which includes the Google Lens feature). There are two ways to do this: You can use the Google Lens Scanner or the main functionality of the Photos app on your iPhone while viewing a photo or screenshot.

First way

First, open the Google app and tap the camera icon in the search bar to open the Google Lens interface. Tap the Photos icon and select an image from the list. Instantly, the Google app will scan the QR code and you will see the result immediately.

Second way

Sometimes using the iPhone or iPad photo gallery can be faster to read the QR code directly from the phone screen. When you are already viewing a photo of a QR code or a screenshot saved to your device (in the “Photos” section), click the “Share” button; on the menu that appears at the bottom of the photo, select the option “Find through Google Lens”. In the pop-up window, click the View Results button. This will open the QR code in the Google app. You can now visit the website or copy the URL if you like.

The program is based on the encryption of data recorded in binary format. When viewing them, the device starts reading information in the following steps:

• the device must recognize 3 squares, which are located at the corners of the icon;
• after identifying the first 3 points, the scan of the rest of the surface and the entire square begins;
• presentation of a QR code in the form of a grid, assigning black or white color to each cell;
• grouping into a complete pattern;
• as soon as the scanner has been able to recognize all the data, it must save it and provide it to the owner of the device.

Thanks to the correct reading of information through this program, more data is obtained, fewer errors. The Q R-code is highly secure and can be easily and quickly checked with an Android mobile phone without any effort.

Standard application

The standard QR code reader application is included in all latest generation Android phones. To find it, just use the quick menu.

How to turn on the scanner on your phone:

• Clicking the icon opens the camera to scan the squares.
• Just point the camera at the image and scan automatically.

We read the QR code from a photo or screenshot in the phone.

QR codes don’t surprise anyone today. They have become an integral part of our lives and are used for many things, from opening a restaurant menu to making payments. The principle is simple: point the camera at the QR code, and our phone will automatically open the corresponding page encoded in the code. But what to do when we receive a QR code in a message? For example, in the form of a photo or a screenshot?

We are in 1Gai. Ru figured out what to do in this case, and found ways to quickly read the received codes.

While iPhones directly integrate the ability to scan QR codes into the Camera app, Apple smartphones (and tablets) do not have the ability to scan QR codes from a screenshot or photos. In this case, third-party applications and websites come to the rescue.

How to read QR code from screenshot on Android

Unlike iPhone or iPad, scanning QR codes on Android is much easier, especially if you use the Google Lens app to scan codes (which must be pre-installed on your smartphone) or if you use the Google Photos app as your gallery app default.

Open the Google Lens app and find the QR code image in the Screenshots or Photos section. Select an image and wait for the Lens to scan the code. Once this is done, you can click the “Website” button to open the link.

You can also do this directly from the Google Photos app. Open the image with the QR code in the Google Photos app and tap the Lens button. This will scan the image in the Lens app. You will see the same options to open the link at the bottom.
