The NFC tag is not supported, what should I do? Samsung phones with NFC

Have you ever heard an announcement on an escalator that you can purchase travel tickets in advance in order to avoid standing in lines at the windows where metro employees sell travel tickets?

Those who use only ground transport are forced to go down to the metro to top up Troika - you must admit, it’s not very convenient.
With the new “My Travel Card” application from the Bank of Moscow, you no longer have to waste time in queues, or, once again trying to get into the metro, face the fact of a zero balance on the Troika transport card.

It is worth noting separately that this is truly the first such application that allows you not only to read the balance of any transport card (not only Troika, but also a regular ticket with a chip sold for city ground transport and metro), but also purchase a ticket and immediately write it down it on your existing travel card.

Developing a finished application took a little time, since we quickly created a prototype, and more time was required to customize the solution to work properly on different phone models.

We completed the most critical functions related to linking a bank card, making payments using it, and working with the client’s profile quickly, since this is a well-functioning and stabilized functionality.

Modern technologies do not stand still, dynamically developing and improving. This applies and is fundamental new technology NFC, which has literally taken over the entire world of mobile communications, providing the potential user with even more opportunities at minimal cost.

NFS in Samsung phones - what is it?

The technology is a universal solution for exchanging data between devices. In fact, Samsung NFC is positioned as a short-range contactless network that works at a distance between mobile devices within 10 centimeters. What is noteworthy is that despite the ability to work with open data at such a distance, the network is as secure as possible. Information cannot be lost, nor can the data be obtained by third parties. In fact, the Samsung NFC network is much safer and meets high security standards than the similar Bluetooth network, which has been relevant for a decade and a half.

All Galaxy smartphones with contactless technology

Currently, manufacturers mobile devices are trying to implement this technology into their developments, ensuring an incredible level of quality of the units. Samsung NFC is not far behind, its models today are presented in the following names and modifications:

• Galaxy S8 is a flagship model that works directly on operating system Android version 7.0. Supports the simultaneous operation of two SIM cards, despite the fact that the mobile phone has one communication module. The device screen size is 5.8 inches, resolution is within 2960x1440 pixels. The device’s camera has a resolution of 12 megapixels and has autofocus;
• Galaxy A5 is a device in the budget segment, the main focus of which is solely on camera resolution. Like the older modification, it runs on the Android operating system, version 6 and higher (depending on what was installed at the time of sale). Supports simultaneous operation of two SIM cards, between which you need to switch while using the phone. The screen has a diagonal of 5.2 inches and a resolution of 1920x1080 pixels. The advantage of the unit is its camera, which has a resolution of up to 16 megapixels, with provision for best quality autofocus shooting;
• Galaxy S7 – the technology was actively used by the manufacturer before, which resulted in the creation of a whole series of devices that support a fundamentally new standard for wireless data transfer. Smartphones run on the Android operating system, version 7.0, and provide the ability to connect two SIM cards. The mobile phone screen is standard for its market segment, has a diagonal of 5.1 inches, and the resolution is 2560x1440 pixels. You can highlight a high-quality camera, the resolution of which is 12 megapixels, and there is also an autofocus option.

Does Android Pay work on Samsung phones?

The issue of payment compatibility is quite problematic. Android functions Pay, which are being actively implemented in new mobile phone models. The problem is that each manufacturer tries to develop its own standards.

It is worth noting that in their structure, the services of Android, Apple and Samsung are fundamentally similar, which allows them to be used in parallel with each other and ensure that all stated payment requirements are met. As gadget users note in reviews, sometimes there are malfunctions in the Android payment system on devices of various modifications of the Galaxy S7, which is not surprising, taking into account the fact that the smartphone is actually the first from Samsung to use this technology in full.

Difference between Samsung Pay and Android Pay

What is Samsung Pay technology on Samsung mobile phones? The company not only tried to use the accepted NFC wireless communication standard in its work, but also made it possible to use not only certain types of terminals that support the possibility of contactless payment for purchases. The solution actively uses proprietary technology called MST (which translates as “magnetic secure transmission”).

Thanks to the unique capabilities of the new technology, the user will be able to easily pay for his purchase on almost any type of terminal that involves the use of a bank card as a payment instrument. To do this, you will only need to have at your disposal a device compatible with the Samsung payment service that supports this “magnetic” technology. Through the use of MST, the creation of magnetic field, according to its criteria, completely identical to that which has a magnetic stripe signal emanating from a bank card. As practice shows, even store salespeople themselves are not aware of this possibility of mobile devices and are surprised that it actually works in practice.

How to use NFC on Samsung

There is nothing easier for a user than learning how to use NFC technology on Samsung. To ensure data transfer, you just need to activate the software chip (provided that the mobile phone has it in its design).

In the settings, go to the “Advanced” submenu, where the “NFC enable” item is provided, after which the option is activated. After this, Android Beam technology is activated automatically; if this does not happen, you can easily perform the operation manually by clicking on the “Enable” item in the same settings menu. For full operation, you will need to activate both technologies; it is important that neither device is blocked or turned off. When a vibration signal is received, this is the first sign that both devices have detected each other and data transfer within the network can begin. Until the data exchange is completed, it is forbidden to separate your devices, this will lead to the fact that the information will be lost and you will have to do everything all over again.

Previously, we already told you about , which allows you to quickly pay for purchases in stores, link cards, and also about tags that you can assign yourself. But even such a seemingly well-thought-out option has its own nuances and shortcomings, which will be discussed in this material.

Messages and questions often began to appear on the Internet that the NFC tag type is not supported. Yes, this problem is mainly faced by users of devices from the giant Samsung, where models of the Galaxy family are often mentioned, but there are also other models of devices. There are no answers as such on the World Wide Web, and interest in this issue is only growing. We have carried out a thorough analysis for you and identified with which application this occurs. this problem why it appears and is it possible to solve it.

If you are reading this material now, then, most likely, you are an active user of the Moscow metro, because this is where the problem with labels arises.

The Troika card is a specialized card that allows you to quickly top up your balance for travel on various transport in Moscow. The system was introduced back in 2013, and has been actively developing since then.

In 2015, the first version of the My Travel Card application was released, where you could enter all your card data using NFC technology and pay for travel not with a card, but with a smartphone. And this is quite logical. Now every user has a phone, so paying in this way becomes even faster and more convenient. And if you might have forgotten your card at home, you’re unlikely to forget your phone!

This is where the whole problem lies. As soon as the “My Travel Card” application appeared for paying for travel, including support for NFC technology, many users decided to install this program on their smartphone and try it in action, but encountered a problem when, when trying to scan or pay, a “tag type” notification appeared NFC is not supported." Once again, as a rule, this problem is most often observed on Samsung devices.

The main cause of the problem

Not only must your device have built-in NFC, but the phone must also be compatible with Mifare Classic technology. If this compatibility does not exist, then no one guarantees correct operation for you. See the table below for which smartphones have this functionality.

This standard was developed back in 1994 and has since been actively developed and supported, remaining the most popular brand among contactless cards. Actually, that’s why it is used in Russia in the metro. But not all smartphone developers add support for this standard to their devices, which is why similar problems arise!

How do I know if my smartphone supports the application?

At a minimum, there must be a smartphone based on Android 4.0 or higher with NFC support.

As mentioned earlier, the NFC technology itself must support the Mifare Classic standard, and this can only be verified in practice.

On the Bank of Moscow website you can view a list of models that support this technology, but keep in mind that the list is not final. This is only a small percentage of all those devices that will work with Troika cards. To view, go and find the item "List of phone models". Click on a tab to view all models.

For convenience, we also present this table:

Whether your smartphone will support the technology or not depends on the developer himself. If the smartphone manufacturer has signed an agreement with NXP Semiconductors, then support will be provided. If not, then the “My Travel Pass” application will not work correctly on such devices.

Nuances that many did not know about!

You can pay for travel not only from a bank card, but also from your mobile phone account. This is supported by the big three operators - Beeline, MTS and MegaFon. But there are nuances here too.

In addition to NFC technology, additional Mifare Classic technology, you must have a special SIM card, which is also designed specifically for contactless payment standards. Moreover, all three mobile operators have developed these SIM cards to allow payment.

The subscriber needs to come to a mobile phone store and exchange his old one for a new generation SIM card. Next, you will simply bring your smartphone to the reader, and the system will automatically debit funds from your mobile phone. If you do not exchange your old card for a new one, similar errors will appear in the “My Travel Card” application.

You can view the full list of supported devices on the MTS website.

As you can see, there are two options for paying for travel in Moscow, and which one to choose is up to you.

With the help of technologyNFC you can not only transfer data from one cell phone to another, but also pay for purchases(for example, purchasing food products in a supermarket).

The decoding is simple - NearFieldCommunication, which, when literally translated into Russian, means near-field communication or communication in nearby space.

Initially, this technology was used for fast contactless payment. Now NFC replaces the plastic bank card and Bluetooth and combines them in one system, which is a fairly practical invention to use. Do you want to make the process of paying for purchases or transferring files easier? Let's figure out how to find out if your phone, tablet or laptop has NFC.

The history of the appearance of technology in the telephone

It is believed that this is a relatively young development. Its appearance dates back to 2004: it was during this period that three famous companies Nokia, Philipps and Sony organized the “NFC Forum”, and three years later they integrated the first NFC tags into a Nokia phone.

Smartphone models that support NFC

It should be noted that not all phones support this data transfer technology. It is known that the following devices have NFC support:

• Apple iPhone (from 6S and 6S Plus models);
• new items from the Galaxy line from Samsung and smartphones from other manufacturers on the Android platform (starting from Android0).

Checking the device for NFC

Would you like to try the technology in practice, but don’t know if this is possible on your device? Let's check.

To do this, carefully open the back cover of the smartphone or tablet, in a situation where it can be moved away without damage, and inspect the gadget’s battery.

When NFC development is present, you will see this abbreviation there. If the cover of the phone/tablet is not removable, the corresponding icon or abbreviation will be located on the outside.

If for some reason you do not want or cannot remove the cover, you can make sure that this method of communication is available in the device settings.

Find the “Wireless Networks” tab, then “More...” and if NFC is available on the device, then there will definitely be a corresponding item there.

How it looks, look at the photo above or in video instructions on how to How check correctlyNFC on your phone:

NFC activation

If you find it on your device, you need to activate access to the technologyNFC. You can do this as follows:

1. go to the “Settings” section and then “Wireless networks”, “More...”, where previously you could verify the presence of NFC;
2. confirm by clicking on the item “Allow data exchange when combining > device name > with another”;
3. Android Beam is immediately activated on your Android smartphone. If this does not happen, click on it and select “Yes” so as not to disrupt the system;

NFC can also be activated in quick menu, in the same place where Wi-fi is turned on. This is done by touching the NFC tag.

Watch the video for more details:

What should I do if my device does not support NFC?

Don't worry if you don't find the built-in feature, there is a way to connect NFC to your device. But this can only be done if the panel cover on the back and the SIM card hole on your smartphone/tablet are removable . Installing NFC in this case will not be difficult.

Installing an NFC module

The optimal solution is to install a special module - an external communication device. It is compatible with almost all smartphones, is easy to use and gives access to NFC without purchasing a new phone.

Types of modules and methods of their implementation

Main types: chips, SIM cards, external devices, stickers. The latter of them come in two types: passive - which do not allow the exchange of data, and active - they use Bluetooth and Wi-fi communication channels for transmission, which significantly increases energy consumption.

Such stickers are attached to the outer shell of the phone, which is also not very practical.

The most popular of them are:

• NFC SIM card. Now available for purchase from most mobile operators. You can find out about the availability of such a SIM at a communication store. You just need to install ready map to your phone or tablet. This type of module is the most affordable and easiest to install.
• NFC antenna. The second method for which you will need to purchase an NFC antenna. This can be done in a communication salon. Next, the antenna is attached to the SIM card and inserted into the device.

As you have already seen, install the module quite simple and safe : You don't need to download any additional apps or programs. However, these services do not completely replace Android app Pay are just some of its many functions.

How to use an NFC tag

An NFC tag is a miniature device in the form of a chip that can be attached almost anywhere: from a phone to insertion under the skin!

We won't use such radical methods, but it's worth noting that contacts, settings, a URL, and other data and commands can be placed on the chip. All gadgets can support the tag.

Data exchange via NFC

The technology can also be used to transfer files.

To transfer data you must take the following steps:

1. make sure that you have completed NFC and Android Beam activation;
2. unlock the device, exit “sleep mode”;
3. check the devices are detected with each other;
4. connect;
5. transfer data between devices;
6. at the end a specific sound signal will sound.

However, not all types of files can be transferred this way. For example, applications cannot be sent.

Advantages and disadvantages of NFC

The main advantages are:

• low price;
• small dimensions of the device;
• high transmission speed;
• support on almost all mobile devices.

It is worth highlighting the disadvantages:

• relatively short range;
• Not all devices are equipped with an NFC chip.

So, thanks to these notes, you have learned quick and simple ways checking your device for the ability to transmit information and interact with other technical means using Near Field Communication. Following simple instructions In this article, you can also find out for yourself whether your smartphone has this technology, you will be able to integrate NFC into your phone and transfer the necessary files at high speed.

The NFC tags I ordered arrived and I started experimenting with them. I’ll try to describe here what NFC tags are and my first experience of using them on a phone.

NFC (Near Field Communications) is a fairly new, but already widely used method of communication over a very short distance - 3 - 5 cm. Maximum speed information exchange - about 400 Kbps, full-duplex data exchange is supported, that is, in both directions, operating frequency is 13.56 MHz, connection establishment time does not exceed 0.1 s, operating mode is point-to-point. You've probably seen NFC in action using the example of subway or public transport turnstiles.

NFC controllers are now often integrated into smartphones; for example, most Lumia models or Android phones have had them for quite some time. But the “most perfect” phone, designated by a gnawed apple, traditionally lags behind - it seems that NFC is in the iPhone 6, but its capabilities are greatly reduced, because it was apparently considered “unnecessary” in Cupertino. Therefore, let’s put the iPhones aside and try on normal devices.

So, NFC can be either active (the controller in the phone) or passive, they are called labels or tags. This is usually a very thin chip with an antenna imprinted directly into paper or plastic. It does not have a power source (battery); it receives energy from the field induced by the active controller. Subway cards contain just such chips. They are very cheap, the retail price for “clean” tags is 20 - 30 rubles, and if you buy in large quantities. even 3-5 times cheaper.

Various information can be written to this chip many times, but not very much: from 140 bytes to 512 bytes. They say there are more, but I didn’t specifically look for them and they are much more expensive.

To register you need special program on the phone, for example:

The recording process itself is extremely simple: you need to select the type of message, possibly enter additional parameters and attach the tag to the phone. The phone beeps and that’s it - the tag is recorded!

There are quite a few types of messages, but many depend on the specific OS. For example, in Android you can write down the Wi-Fi access key, and the phone will immediately set up and connect, but in Windows Phone this trick will not work! At most, you can record a text message with the Wi-Fi key and a command to open the desired settings page. Apparently, the developers considered such a complete setup on someone else's Wi-Fi network unsafe. You can write down any URL that opens in the browser, check in in social networks, phone number to call or SMS.

But what I liked more was the ability to open almost any application on the phone. That is, I brought the phone to the tag, and the desired program immediately opened (if you check the box “I trust this program” for the first time). For example, it is often advised to stick a tag to a wireless charger in a car. That is, you insert the phone into the holder on the windshield, it starts charging and the navigator opens on it.

For now, I pasted the mark into the notepad and now, when I come to work, I take out my phone and put it on the notepad, the list of tasks for today opens on the phone.
