How to find out if NFC is available on your phone. About NFC iPhone and related problems

Despite the fact that almost everyone has access to information, not every mobile device user knows what NFC is in a smartphone, what this technology is for and how to use it.

How does NFC work?

NFC is a computer technology that has gained fame, allowing you to make purchases in stores and pay for services without money (cash) or a bank card. This is a new and virtually secure method of contactless payment. The communication interface is used in a smartphone. To pay, simply bring your smartphone with the installed module to the terminal.

The principle of operation of the NFC module in a smartphone is the same as that of plastic cards with a wireless communication function.

There are several known ways to use the NFC interface in a mobile device. Most often, people use it to make contactless payments. A bank card is attached to the mobile device. It is difficult to intercept bank card data due to the small range of this module. In this case, unattended, lost or unlocked smartphones are more dangerous.

The payment transaction is carried out in several stages:

• Purchasing and activating a card with PayPass technology.
• Install your issuing bank's application.
• Activating NFC technology on a mobile device.
• Applying the card to the smartphone, starting the data reading procedure.
• Receive a PIN code from the bank via SMS for transactions.
• Payment for goods and services using a smartphone and a payment terminal.

There is another, less common way to use NFC technology. Using the module you can exchange data. Files are transferred from one mobile device to another, and a special Android Beam application acts as an intermediary. But exchanging data in this way is inconvenient, since the transmission speed is low and the range is minimal. The method is suitable for sending text messages, but nothing more.

The third way to use the technology is to record and read tags. Certain actions are assigned to a tag, such as sending a message, calling a contact, or going online. The function is suitable for people seeking to optimize personal time and automate their everyday life.

How to set up NFC for contactless payment by phone

NFC setup consists of the following steps:

1. Module activation. The user goes to the “wireless networks” settings section and checks the box next to the NFC name.
2. Agent selection. The user has the opportunity to select and install the application of the issuing bank of his card for data transfer.
3. Module binding. The user moves the device closer to the card with PayPass technology until the signal goes off.
4. Confirmation. Receive an SMS code to complete transactions.
5. Usage. Payment for goods and services in terminals with NFC technology.

Is it possible to buy a separate NFC module for your phone?

Purchasing a separate contactless communication module for a telephone is possible in the form of several solutions. You can use a special SIM card or antenna with your mobile device. The SIM card works the same as its counterparts. It is produced by mobile operators and installed in a smartphone in a special connector. The SIM card opens up all the possibilities of contactless transactions using a mobile phone at the level of Apple Pay or Samsung Pay.

NFC antenna is a radio device that performs the functions of an NFC module, but the user will have to install it on their smartphone themselves. The antenna is glued to the SIM card and installed under the phone cover. On models with a non-removable cover, installing modules is more difficult, but theoretically possible.

What are nfc tags

Recording and then reading tags is necessary to automate everyday tasks. Tags are analogous to QR codes. When approaching the tag, the smartphone reads it using the NFC module and performs encrypted tasks. For example, it opens a video on YouTube, an email, an SMS message, or a call to a contact from the phone’s address book.

A smart ring or bracelet with NFC function is a new development from Chinese engineers, suitable for smartphones running on any operating system. The bracelet can be selected to suit any hand size (the same with the ring). The device weighs very little and fully supports NFC technology. The processor functions, for example, in the band 3 nfc model are performed by a special chipset. Thanks to the chipset, the smart bracelet helps the smartphone exchange data via a contactless channel, maintaining the necessary security. Data on a device can be overwritten hundreds of thousands of times.

The bracelet stores payment information, notes and other personal information. It’s easy to view information - just hold the bracelet to the smartphone screen. The bracelet will instantly establish a connection with the phone and remove the lock from the screen, and can also serve as a “hot” button. For example, when you bring the bracelet to your smartphone, the camera, Internet or social network application will instantly open.

How to find out if your phone has NFC

The NFC icon, if the smartphone has this module, can be found in the settings menu. On an Android device, you need to do this:

1. Open the settings menu.
2. Open the “wireless networks” section.
3. Read the list of networks supported by the device. If the list does not include a network called NFC, then the smartphone cannot exchange data using this technology.

Is NFC technology safe? Won't the money be stolen?

People who have been using contactless bank cards for a long time do not need to explain what NFC technology is. This payment method is safer than the standard method of activating a PIN card in the terminal, since no one sees the code. Even after stealing a smartphone, an attacker will not be able to withdraw more than 1,000 rubles from the card due to widespread restrictions on the limit of amounts in contactless transactions.

Some media reported that attackers have developed terminals that they use in crowds, quietly withdrawing money. But this is only possible if the smartphone is not locked.

Advice: if the fraudster managed to write off money illegally, the account owner can always contact the bank and ask employees to track the movement of funds. The attacker’s account will be quickly found and the money will be returned to the owner if he (the fraudster) has not spent it yet.

Programs for creating NFC tags

There are already many separate applications for creating NFC tags, but their number is constantly growing. The following specialized programs are in great demand:

• ABA NFC. The program creates standard labels for various purposes.
• WiFi Tap. The program quickly connects the device to a wireless network without entering a password.

NFC technology is based on the principle of short-range wireless high-frequency communication. It allows you to transfer data between devices with the maximum level of security. This was the main reason for the appearance of NFC chips in phones. So that you can choose the right device, we have compiled a rating for 2018-2019, which includes smartphones with NFC support in different price categories.

Budget phones with NFC

Price: 11,670 rubles

The ranking of cheap phones with NFC opens with Samsung Galaxy J4+ (2018). This is one of the company's few successful models in 2018. If we talk about its advantages, then I would immediately like to mention the screen with a diagonal of 6 inches and a resolution of 1480 by 720 pixels. Despite the fact that the matrix was made using IPS technology and not AMOLED, it gives the user a detailed picture with a high level of contrast and rich colors.

The features of the smartphone include face unlocking. This technology is gradually replacing the fingerprint scanner, and the fact that it can be found in a solution for such a price cannot but rejoice. It works clearly, although in a dark room the face of the owner of the front camera may not be recognized. The Samsung Galaxy J4+ (2018) has no critical disadvantages. The only thing that can upset you is that the screen frames are too large, which spoil the appearance of the gadget and make it look like a phone that costs up to 10,000 rubles.

Samsung Galaxy J4+ (2018) 3/32GB

Sony Xperia L2

Price: 12,350 rubles

The Sony Xperia L2 is one step away from winning the top of the list of inexpensive phones with an NFC chip. In addition to the signature angular design for which Sony smartphones are known, it offers its user a 5.5-inch screen with a resolution of 1280 by 720 pixels. Despite such a low resolution for 2018, the image on the display is quite rich and bright, and the colors are saturated. In terms of compactness, the gadget significantly outperforms most modern “shovels”. Dimensions Sony Xperia L2 – 78x150x9.8 mm

The entry-level MediaTek MT6737T processor and 3 GB of RAM cope with all everyday tasks, but it has no reserve for the future. The main disadvantage of the model is its autonomy. This is a little strange, since a 3300 mAh battery should easily be enough to support simple hardware and a low-resolution screen. However, in reality it is hardly enough for a day of active use. Despite this, if you like compact phones with NFC, then the Sony Xperia L2 is what you need.

Huawei P Smart 32GB

Price: 12,530 rubles

Huawei P Smart is the best budget phone with NFC. The gadget was equipped with a bright 5.65-inch display with a resolution of 2160 by 1080 pixels. Due to the fact that it has natural color rendition, the picture pleases with its quality in any work scenario, from everyday use to watching videos and playing games. At the same time, thanks to the good stuffing of the Kirin 659 processor and 3 GB of RAM, you will be able to play absolutely any projects, but in particularly demanding ones, such as PUBG and Fortnite, you will have to lower the settings.

Huawei P Smart is also strong with its speaker. Even at maximum volume, when playing music, you will be pleasantly surprised by the sound quality. By connecting a high-quality headset to your smartphone, even spoiled audiophiles will be satisfied. There are some drawbacks, but for the price they are not so critical - the lack of 5 GHz Wi-Fi and a slippery case.

Huawei P Smart 32GB

Middle price segment

Huawei P20 Lite

Price: 16,390 rubles

Huawei P20 Lite is a real find in terms of wireless interfaces. Not only is there an NFC module, but Wi-Fi supports a/b/g/n and even ac standards, while it is also capable of operating in two frequency ranges - 2.5 and 5 GHz. While only a small number of consumers will appreciate this, the 5.84-inch display with a resolution of 2280 by 1080 pixels will appeal to everyone. It pleases with natural color rendering and bright colors.

Huawei P20 Lite is equipped with face unlock, while the developer did not abandon the fingerprint scanner. Apparently, for those who will not like the new technology. Considering that both scanners work great, it is quite difficult to choose the best one. The advantages of the model include a rich set of functions, which are presented in the proprietary firmware interface. Among them there is even the opportunity to hide bangs. The disadvantages of the model include the sensitivity of the case to damage, as well as the lack of USB 3.0. Despite this, if NFC communication is important to you, then the Huawei P20 Lite is definitely worth your attention.

Yandex.Phone

Price: 17,990 rubles

Yandex.Phone is a smartphone with which our IT developer decided to debut on the relevant market. However, the device turned out to be ambiguous and the launch cannot be called successful. The main advantage of the gadget lies in its shell from Yandex, namely the voice assistant Alice. It works even when the phone is locked, and with its help you can set an alarm or find the nearest cafe. The 5.65-inch display with a resolution of 2160 by 1080 pixels turned out to be quite good. It has excellent detail and rich colors.

The disadvantages of the smartphone are its weak hardware and battery life. Thus, the Snapdragon 630 processor is already noticeably outdated and is only enough for simple games and everyday processes, and the 3050 mAh battery can hardly last a whole day. However, these disadvantages cannot be compared with the performance of the cameras. Not only does the second module here not perform any of the usual functions, but when shooting, the image is replete with blurry frames and insufficient dynamic range. Considering all this, many Chinese phones with NFC look preferable to Yandex.Phone, but the firmware features allow the device to take second place in the ranking of smartphones under 20,000 rubles at the beginning of 2019.

Smartphone Yandex.Phone

Honor 8X

Price: 16,990 rubles

In the ranking, which presents mid-price smartphones with an NFC chip, Honor 8X is in the lead. The gadget has a memorable appearance - the back panel is made of 15-layer glass, thanks to which the smartphone stands out among most of its competitors. The device is powered by the Kirin 710 processor. This is not the top-end chipset in Qualcomm's arsenal, but its performance is sufficient for stable operation in instant messengers and browsers.

On the front there is a 6.5-inch display with a resolution of 2340 by 1080 pixels. It not only occupies 91% of the entire front part of the smartphone, but is also able to please the owner with an image with rich and bright colors, as well as a high level of detail. True, it also has a disadvantage, which is the insufficient brightness reserve. Because of this, using a smartphone in the sun is quite problematic.

The best flagships with NFC

Xiaomi Mi8

Price: 24,990 rubles

If we talk about the best smartphones with an NFC module, then we cannot fail to mention the Xiaomi Mi8. The gadget is equipped with a 6.21-inch AMOLED display with a resolution of 2248 by 1080 pixels. All the features of the matrix are evident here - natural color rendition, maximum viewing angles and high image detail. The presence of the Snapdragon 845 processor, which is the most powerful on the market at the moment, is also pleasing.

Xiaomi Mi8 is good in terms of cameras, the rear one turned out especially well. It is represented by two 12 MP modules. Due to the presence of optical stabilization, 2X optical zoom and an aperture value of F/1.8, the pictures are obtained with the correct color balance and are quite sharp. If you feel that the colors in your photos are not saturated enough, you can always turn on the intelligent shooting mode, which will correct this. The only disadvantages of the model include the similarity in design with the iPhone X, as well as the lack of a 3.5 mm headphone jack.

Samsung Galaxy S9

Price: 37,770 rubles

The flagship of a well-known company will appeal not only to fans of the NFC module, but also to those who appreciate the photographic capabilities of a smartphone. The main camera of the Samsung Galaxy S9 is represented by a single sensor with a resolution of 12 MP and an F/1.5 aperture. It is also equipped with optical stabilization, which together results in images that are rich and detailed, so you can safely take the Samsung Galaxy S9 with you on vacation and then enjoy the footage.

Exynos 9810 is a processor that will give you amazing performance. With it you will not encounter any problems either when solving everyday problems or when launching games - even in PUBG you can safely set the maximum graphic settings. The model has disadvantages, although they are not too significant. Thus, the body of the gadget is not scratch-resistant, and the 3000 mAh battery barely lasts for a day. If you use your smartphone actively, then most likely by the middle of the day you will have to look for an outlet.

Samsung Galaxy S

Apple iPhone XS Max

Price: 85,990 rubles

If you like premium smartphones with an NFC chip, then the best option for you will be the Apple iPhone XS Max. The top representative of the latest generation of iPhones is equipped with the most powerful Apple A12 Bionic processor. At the moment there is no work scenario in which it would use its full potential. Apparently, the situation will not change in the next couple of years and you will be able to run all games at maximum settings. You will enjoy them on a 6.5-inch display with a resolution of 2688 by 1542 pixels. Its matrix is ​​made using AMOLED technology, and therefore the viewing angles are maximum and the color rendition is natural. All this is complemented by rich colors and a high level of contrast.

For photography enthusiasts, the Apple iPhone XS Max is equipped with a dual camera with a resolution of 12 MP for each sensor. The rear camera has rich functionality - optical stabilization, optical double zoom and a set of intelligent scene detection. Thanks to all this, the Apple iPhone XS Max is able to accurately capture any moment of your life. The disadvantages of the model include the absence of an adapter from 3.5mm to Lightning and native charging with a power of 1 ampere.

You've probably already heard about such a feature as NFC on your phone. It is quite common today, many flagship devices (smartphones, watches, etc.) are equipped with it, and is gradually reaching inexpensive devices. Manufacturers and sellers often focus on NFC, attributing the most unusual and useful capabilities. However, not every user knows what NFC is and what its main functions are in a phone and other devices. Today we will try to tell you about this technology in detail and clearly.

NFC on a phone - what is it?

People first started talking about NFC back in 2004. At that time, three giants of the mobile industry Nokia, Philips and Sony set out to create a wireless interface that would work when two devices were close together. A forum was organized and work began.

NFC, Near field communication (“near field communication”) is a wireless data transmission technology, the distinctive feature of which is a short range (up to 10 centimeters).

Essentially, the technology is based on contactless cards made according to the ISO 14443 standard. Such cards are used to differentiate access to different premises or pay for services. NFC became a simple extension of this standard, aimed primarily at mobile phones.

Technology Specifications

To make the concept of NFC technology more clear to you, you cannot do without the technical characteristics of the technology. Don't worry, it's quite simple:

• The key standard is ISO/IEC 14443, which describes frequency ranges, modulation methods and data exchange protocols for short-range contactless cards based on magnetic field induction
• Induction coils are used to communicate between two NFC devices
• NFC operates at a frequency of 13.56 MHz
• Data transfer speed is no more than 400 Kbps
• It only takes 0.1 seconds to establish an NFC connection
• NFC has a very compact size and low power consumption, which allows the interface to be used in a wide variety of gadgets

Why do you need NFC on a phone or other device?

If many users turn a blind eye to dry specifications (although they should read it), they are unlikely to miss the information about why NFC is needed in modern smartphones.

• Firstly, a phone or other device with NFC can replace a contactless card to pay for metro travel, access to premises, or other similar purposes - just touch the device to the turnstile.
• Secondly, NFC is used to pair a phone with another phone that also has this interface; the second device today is other devices - even washing machines; pairing makes it possible to transfer data between devices, however, due to the low speed, this method is irrelevant (this speed is enough to transfer any commands from the device to the device).
• Finally, thirdly, a phone or watch with NFC can replace cash or a bank card. How? It's very simple: many terminals in stores today support contactless payments, that is, to pay for purchases you just need to tap your smartphone. It’s very convenient, but in our country the technology is just gaining popularity.

Why do we need NFC if we have Bluetooth and other interfaces?

Many users equate NFC and Bluetooth to the same type of interface, which is somewhat incorrect. Yes, we have two wireless technologies, and the second one is more popular. The key difference is the range. If in the case of Bluetooth we have tens of meters, then NFC in phones transmits data over a few centimeters (that is, the devices need to be brought quite close to each other). So is Bluetooth better?

Not really. A large range of action is not always necessary, and in some cases it even becomes a disadvantage of the interface. You remember that NFC on your phone allows you to pay for purchases? In this case, the device practically touches the terminal (the range is small), which guarantees maximum protection of the transmitted data of your bank card. When using interfaces with a more serious radius, which can cover tens of meters around, there is a danger of information interception.

The same can be said about the transfer speed, which in the case of NFC is really low by today's standards. However, the technology is not aimed at transferring large files, as when using Bluetooth. And this has at least two advantages - reliability and lower power consumption. The low data transfer speed will not allow attackers to quickly “extract” important information from your smartphone.

Another obvious advantage of NFC in phones is low power consumption. The technology consumes significantly less energy than other interfaces, saving precious minutes of the smartphone’s life.

Speaking about the advantages of NFC in a phone, one cannot fail to note the low cost of implementing the interface into devices. It's surprising that it is still so rare.

Flaws

Despite the advantages, which at first glance are simply huge, like any technology, NFC has a number of unpleasant disadvantages. The most obvious are the transfer speed and range, which every user will have to put up with. But, as already noted, these features can rather be attributed to the advantages of NFC.

There are also more serious problems associated with technology. The first of these can be considered its wide distribution. What's wrong with that? The fact is that every large company, having noticed the potential of NFC, began to independently modify the interface, introducing proprietary developments in their products. It is clear that the changed standards cannot boast of universality - they only work with their own kind. Users suffer from this.

No matter how hard developers try to improve NFC, holes are constantly being identified that can be exploited by attackers. So, in 2012, at one of the conferences, security specialists managed to download a special exploit (), which took control of the device. Naturally, the vulnerability has since been fixed.

Other information about NFC vulnerabilities appears on the Internet from time to time. In most cases they are far-fetched. For example, there is an opinion that using jammers (electronic warfare equipment) it is possible to modify the data on the device, but this is practically impossible due to the impossibility of establishing communication in this way.

As a result, we can say that NFC on a phone is one of the most secure technologies. At least, so far there have been no mass attacks by cybercriminals through interface vulnerabilities.

How to check if your phone has NFC

So, we figured out what NFC is, its specifications and features. Now let's move on to checking your smartphone to support this technology. There are several ways to do this:

• View the technical specifications of the device on the Internet or on the manufacturer’s official website - pay attention to the “Interfaces” or “Communications” section (as a rule, the manufacturer does not lose the opportunity to once again declare NFC support).
• Typically, if a smartphone supports NFC, the corresponding item appears in the “Wireless connections” section in the phone settings.
• Some smartphone models that have a collapsible body allow you to see NFC for yourself. As a rule, the transmitter is placed under the cover, connecting to the battery with special contacts. Look for an identifying mark - this could also be a wireless charging receiver.

Often, in the case of tablets, smart watches and other equipment, you can find a special pointer on the case that confirms the presence of NFC. By the way, when pairing, you need to bring the second device exactly to the image location.

Which phones have NFC

Almost every flagship of recent times has NFC; increasingly, the interface can be found in the middle segment; if desired, you can even find budget smartphones that support the technology. For example, here are a few models:

• Among the flagships: iPhone starting with iPhone 6S; Samsung Galaxy S, starting with S3, LG, starting with G4 (and a number of K-series solutions), Xperia X line from Sony; and any other well-known manufacturer has at least a couple of flagships with NFC.
• Among the available segment(up to 20,000 rubles) : the latest smartphone models Samsung Galaxy A and J, Honor 8, Huawei Nova, Nokia 5 and 6, and many others.
• Among the most accessible: Nokia 3, ASUS ZenFone 2 (one of the cheapest smartphones with NFC), and many Chinese phones support NFC.

How to use NFC on your phone

Let's move on to using NFC. To start working, we need to transfer the technology to an active state. To do this, follow the following instructions:

1. go to “Settings” of your phone;
2. go to the “Wireless Connections and Networks” section;
3. turn the toggle switch to the active state opposite the “NFC” item.

That's it, after that we can use the interface.

Transfer files using NFC

As already noted, the NFC interface is not very suitable for transferring large files due to its low speed. And besides, not everyone wants to hold smartphones next to each other while the film is being broadcast. However, NFC is great for small files (notes, links, contacts, addresses from maps, etc.), which is facilitated by the high pairing speed.

To transfer data via NFCboth phones must support the technology, in addition, it must be active. Also, none of the smartphones should be locked.

The transfer process is somewhat reminiscent of the days of Siemens and IR ports:

Until recently, only flagship smartphones, and not every company, could boast the ability to make contactless payments. The fact is that for this function to work, you need not only NFC, but also the appropriate software.

On usedApple Pay- a very common payment method in America, and in Russia it is gaining enormous popularity.Samsungwas also one of the first to introduce its own payment system with a simple nameSamsung Pay. In addition to these market giants, some other companies have proprietary payment systems.

Quite recently, a significant event occurred for Android device users - the Android Pay application was introduced. It has become universal, that is, it allows you to make payments from any Android phone with NFC.

How to add a card to Android Pay to pay for purchases via phone

1. to pay using phone and NFC we will need, of course, a special application;

These can be branded ones listed above, or universal Android Pay. All are available for free in online stores. We'll take a closer look at Android Pay.

1. When installing the application, you must provide it with the required permissions, connect to your account (you can use Google);
2. Now we need to add bank cards from which payments will be made;

You can find out about participating banks that provide services by opening the Android Pay context menu (three dots at the top right) and selecting the desired item.

1. to add a card, click on the plus at the bottom right;
2. from the proposed options (“Add a debit card”, “Add a loyalty card” and “Add a gift card”), select the one you need;
3. in a new window, which will be presented as a camera application, you need to place your card in the frame;

You can also specify the card number and other data manually by clicking the appropriate button.

1. Having specified all the required information, Android Pay will offer to confirm the binding (for this, an SMS message is used in which your bank will send a code, or a proprietary application, for example, “Sberbank Online”).

That's it, you can rid your wallet of one card that will no longer be useful to you. Add other cards in the same way so you don’t needlessly carry them around with you.

How to pay using Android Pay and an NFC phone

Everything here is generally very simple. As they say, even a child can handle it, the main thing is that NFC is supported in the phone.

Just pay attention that the terminal must support the contactless payment function. It is indicated by a special symbol (Android Pay uses a distinctive green robot). As a rule, such terminals already exist in every major shopping center, but still not everywhere.

Payment occurs in two steps:

1. unlock your phone with NFC;
2. bring it to the terminal;
3. hold until a tick appears.

If everything goes well, a corresponding notification will appear on the terminal. Your bank card will be debited as soon as possible. The debit is made from the card that is installed as the main one.

As you can see, paying with NFC on your phone is very easy. You are not even required to enter a password (not always).

If the purchase price is over 1000 rubles or you make a payment using Android Pay for the fourth time in a row, the system will ask for a password. This was done, as you might guess, for security purposes.

Near field communication (NFC) is a new short-range wireless high-frequency communication technology. Nfc chip< дает возможность обмениваться данными между разными устройствами, находящимися на расстоянии 10 сантиметров. Данная технология является простым расширением существующего стандарта бесконтактных карт (классификация ISO 14443), объединяет рабочий интерфейс смарт-карт и считывателя в общее устройство. Такой прибор NFC способен поддерживать связь даже с существующими смарт-картами, а также со считывателями ISO 14443 стандарта, и прочими устройствами NFC и, может быть совместим с рабочей инфраструктурой бесконтактных карт, использующейся уже в общественном транспорте/платежных системах. NFC нацелена, в первую очередь, на использование в мобильных устройствах.

What is an NFC module

A module is an external device that allows for rapid identification using a radio communication channel at a distance. The short-range communication module operates at a frequency of 13.56 MHz with speeds up to 424 kbit/s. This technology is based on the use of specialized chips (including in telephone SIM cards) in communication devices. The widest distribution of NFC technology in the near future is associated with the possibility of using it in conjunction with smartphones and mobile phones: the mobile device is equipped with a module (an external NFC module for the phone is suitable), which will allow the subscriber to make timely payments for services and goods by simply bringing their phone closer to the reader. It is usually understood that funds are debited from the client’s bank account, and not from the account with the mobile operator. communications.

Types of modules

The main types of NFC modules are SIM cards, external devices and chips. You can also use additional devices for communication and payment, such as NFC modules and stickers. The NFC module for the phone can be ordered separately, or it can be purchased already in the phone as built-in equipment. Stickers are attached to the phone body. There are passive and active. The first ones are not able to exchange data with the phone and do not allow you to write information to an NFC device through the communication channels of a mobile operator. Active - use the Wi-Fi/Bluetooth communication channel to communicate with the device, which leads to increased power consumption or the need to constantly recharge the module. A common drawback of such modules is the presence of fastenings.

How to add an NFC chip to a smartphone

The first option is an NFC SIM card. They are produced by many mobile operators. Install the ready-made functional card into your smartphone and pay for purchases with a light touch on the terminal. Of course, this cannot be called a high-quality replacement for Apple Pay, since ongoing transactions are not encrypted and do not require fingerprint identification. In addition, the user will probably have to open a new account with the mobile operator/bank. However, if he is a holder of a plastic card from one of the banks, the problem will disappear by itself. All you have to do is visit a mobile phone store or a bank branch and get a SIM card.

NFC antenna. Another working method. For all users whose phone or smartphone does not have a “near-field” module in their arsenal, the path to “contactless” is a little more difficult. You will have to either replace the device, which is irrational, or equip it with an NFC antenna yourself. Contrary to popular belief, this is much easier to do than previously imagined. To do this, you need to purchase a special external NFC antenna. This can be done in cellular communication stores, then, by gluing it to the SIM card, install it under the cover of your mobile device.

A small note: owners of devices with a non-removable back cover and a side hole for SIM cards will not be able to perform this operation. The module can be installed in almost all phone models. This solution is simple and will be used until phones with built-in NFC modules appear on the market.

Near Field Communication or simply NFC is a short-range wireless communication technology that allows you to exchange data between devices. It is becoming more and more common on smartphones, although for some reason mainly in the more expensive price segment. It is surprising that some “high-end” smartphones do without NFC at all, although this wireless communication technology is one of the most popular.

Some users do not even know if their smartphone has NFC technology. How to find out? Now you'll find out.

Does your smartphone support NFC?

The first method is the simplest: swipe from the top of the window to the bottom to bring up the quick access panel. Like this:

Look for the NFC item. Found it? Congratulations, your smartphone supports this technology.

If there is no such point, all is not lost. Open settings.

Tap on the “More” line in the “Wireless Networks” section.

See the NFC line with the switch? Congratulations, the technology is supported by your smartphone.

If nothing works, you can try using a third-party application. In the Play Market in the search write nfc check.

Choose an application, let it be NFC Check by Tapkey. Install.

After installation, you launch it and immediately see the result: in our example, the NFC module is installed, but is not activated at the current time.

Should you trust the specification? It is possible, but there are some nuances: the same smartphone model may or may not be equipped with an NFC module. Be careful.
