NFC Expert What is the NFC ring used for
An accessory with a contactless payment method allows you to:
- Use it as an electronic key.
- Write down the data of the Troika card on it (relevant only in Moscow).
- Store personal data in text format. Upon contact with a gadget equipped with NFC technology, information can be obtained from the payment ring.
- Pay for public transport services.
- Make contactless payments.
The Visa payment ring was one of the first to appear on the market together with Alfa-Bank. Users have already managed to evaluate all the advantages of the gadget and introduce it into use in everyday life.
However, it is important to remember that one chip can only store information about one means of payment. That is, if you have several cards that you actively use, you will either need to purchase several rings or use alternative payment methods.

What is an accessory?
The ring is made of durable ceramic material, is not afraid of immersion in water and is able to withstand serious mechanical stress. This is a standalone device that does not require recharging and battery replacement.
The accessory is called Visa NFC Ring, PayPass or NFC ring. A special antenna is built into it, thanks to which users can pay for goods and services. Decoration 100% replaces a plastic card, it is more difficult to lose, as it is constantly in sight, on the finger. To pay with the device, you need to attach it with a chip to the place where a special reader is located that receives information.
Appearance
The minimum size is 15.5. On the inside of the gadget, it is easy to notice the logos of the manufacturers – PS Visa and Alfa-Bank.
On the one hand, the accessory can be attributed to modest jewelry that is unlikely to be of interest to diamond lovers, on the other hand, if you look into the future, a quite presentable look of an analogue of a bank card can eventually become a trendsetter and a sign of respectability of the wearer.
How does it work?
Alfabank ring is the same as a financial institution card. The product is designed to pay for purchases in stores and services in self-service machines. Included with jewelry are sold:
- instruction;
- secret PIN in an envelope;
- prepaid card.
Payment instrument limits are quite limited:
- the amount of expenses during a calendar month must not exceed 40,000.00 rubles;
- the balance of money on the balance of the means of payment must not exceed 15,000.00 rubles.
You can top up the ring with transfers from other cards, as well as in self-service machines. Initial limits can be increased over time by contacting the administration of one of the branches of Alfa-Bank.
Since we are talking about contactless payments, many are interested in how safe it is to use the described payment method. Manufacturers claim that it is no less safe than a plastic card. The accessory has a built-in Gemalto chip, designed to make payments completely safe. If the ring is lost, just like plastic, it can be blocked. Since a blocked decoration does not contain any information about the owner, it is impossible to use it in a non-working version.
Troika ring
In addition to decorations for paying for purchases and services, rings will soon appear in the banking assortment – analogues of Troika plastic cards, designed for fast and comfortable payment for public transport.
It is planned to be the first to provide such gadgets with Troikas to citizens using the Moscow metro. Further, decorations will be developed, with the help of which it will be possible to pay for all types of capital, and then peripheral transport.
Note that nowhere in the world is anything like this used. The capital will be the first city where people can pay their fares with original and stylish decorations.
How is it better or worse than a regular card?
There is no consensus whether a smart ring is better or worse than a bank card. Fans of progressive technologies are inclined to believe that Smart Ring is a great solution for everyday tasks. The application allows you to simultaneously perform many functions without the use of additional gadgets.
Another point of view is negative, since the rings from some banking organizations require serious improvement. So, for example, the accessory does not always work when paying for purchases or is completely blocked without good reasons.

How to get?
The described rings have not yet entered the free market. They are tested by individual users. However, if you want to become the owner of an interesting and promising accessory, you can place an order for it on the Internet on the NFC Ring manufacturer’s website.
It will soon be possible to get a ring by placing an order for it at the issuer. While the test period lasts, orders are collected for the manufacture of the described accessory. The preliminary price of Pei’s ring is 53 USD.
What are the pros and cons?
A tempting and yet inaccessible accessory for most users is being actively discussed in the press and on Internet forums. Various sources of information indicate the pros and cons of bank decoration. Its advantages include:
- record speed of payment processing;
- stronger than plastic cards;
- accepted by ATMs and terminals;
- reliable protection of funds and high safety of use;
- there is no need to give to the cashier to make payment;
- extremely simple application;
- nice modern design;
- can act as an electronic key;
- no battery and no need to recharge;
- can be lowered with a gadget to a depth of 50 m.
The disadvantages of the banking ring include:
- a small selection of design options;
- minimized limits.
The main drawback is that at the moment Alfa-Bank is not able to satisfy all its customers who want to have an exquisite analogue of a bank card.
The main advantages of the NFC ring include the following aspects:
- ring is a stylish accessory that is always at hand. Useful not only from a functional point of view, but also complement any style;
- there is no need to take a bank card with you;
- the presence of a security system that allows you to secure the funds in the account;
- resistant to moisture and mechanical stress, so you can wear it while doing sports or taking a shower;
- works autonomously and does not need to be charged;
- can be programmed by yourself at home;
- wide range of models and sizes.
Despite the wide functionality, there are a number of nuances:
- if there is no fingerprint function, an attacker can easily make purchases up to 1000 rubles;
- no biometric security and no PIN code.
Some banks, as a prerequisite for linking a card or account, require you to personally visit a branch with a passport and your card, which is inconvenient for many busy people.
Dangers and pitfalls of such a tool
If the ring is lost, funds can be easily withdrawn from a bank account or credit card until the client blocks access to them. But to block it, you will need to contact the organization’s branch, and this will take time. The accessory does not yet have a sufficiently high degree of protection compared to using a smartphone.
Despite the use of the most durable materials for the production of a smart ring, it is possible to damage it. In this case, transactions using it will stop going through. There were cases when the chip stopped working at the payment terminal for no reason, which caused inconvenience to users.
Information will seem sly when manufacturers say that it can be used and not removed under any conditions. Most materials do not show resistance to sudden temperature changes and do not withstand strong impacts.
The ring is subject to hacker attacks. Fraudsters have managed to develop special devices that allow you to read signals when traveling in public transport. And although many rings have a payment limit of 1000 rubles without a PIN, the risk of incurring losses remains high.
Reviews
Many bank customers have already personally evaluated payment rings and share their experience of using this accessory on various review sites.
“I have been using Visa Pay Ring relatively recently and so far there have been no incidents with payment. It works properly, high quality materials, it looks beautiful and elegant, which is an important criterion for girls. It is convenient to pay for purchases in stores or travel in the subway,” wrote Svetlana.
Alfa-Bank client Valentin also agrees with her, who wrote: “I am a lover of new gadgets, so I bought a smart ring from Alfa-Bank for the sake of interest. I can’t say that I was delighted with the device. There is a bracelet with an identical function and I use it more often. A couple of times payments didn’t go through the first time”
However, there are also negative reviews. For example, Maxim believes that a contactless ring: “A useless purchase for those who travel a lot. The ring does not work in foreign stores. Therefore, it can only be used on the territory of the Russian Federation. For me, in this case, the ring is 50% meaningless. And it is not cheap by my standards – 4500 rubles “

Alexander didn’t like the device either: “I didn’t like the gadget at all. The antenna in it is much weaker than when using a smart bracelet or an NFC phone, so I still carry a card with me so as not to get into an unpleasant situation. My opinion is a waste of money, because there are many nuances in it, especially regarding security. It is very easy to write off money from such an accessory.
Kristina was satisfied with the purchase: “I ordered a ring from China. It came with instructions for the settings, so it didn’t take me a lot of time to use it. I’ve only been using it for a couple of weeks, but I’m very satisfied. Everything is instantly readable, I pay them almost wherever possible.
Whether to buy a payment ring is up to you. But many note that using the already familiar Samsung and ApplePay is still much more convenient, especially if you have a smart watch.
Since the ring has not yet hit the mass sale, most of the reviews about it are an expression of the desire to have a “smart” and beautiful accessory. People wonder how safe it is and express distrust of the contactless payment system that is just beginning to develop.
On the net you can find reviews of those who are among the limited number of lucky ones who got the test version of the gadget. They are all enthusiastic. The new technology is considered promising and promising.
