NFC on phones: what is it? What is NFC? What about NFC on smartphones and how should we vikorist? Support for NFC technology

Hello dear readers of this blog. From this material I will learn about the useful NFC technology. Who already felt a lot about this new product, except for the announcements in 2004. It is possible to most often use smartphones based on Android or iOS, other than other devices where the technology is used, we’ll also talk about those.

NFC(Near field communication) – translated as “near contactless communication”. Є kіlka is significant. It is used to ensure connection between devices on a short distance, which was originally intended for non-contact operations. The actual mutual cost is 10 div.

NFC robot principle

It would seem that the function is greatly diversified from other dartless models, and is also compromised by them. The operating principle of NFC lies in the fact that the device, when the module of this technology is used, operates at a speed of approximately 400 Kbps (obviously Wi-Fi is provided), the interaction is carried out at a distance of 10 cm, so that you can practically use the device one to one, wanting an hour ' ednannya zazvichai mitteve.

The NFC module is very compact, so it can be installed not only in smartphones, but also in modern times. The veins have a lot of energy. In order for the module to work in the required direction, there is an antenna near the device. Ring on the phones in the back. In this way, connecting with devices can ensure mittev contact. If the device is large in size, such as a tablet, then it is more difficult to find the point of interaction.

Because of the safety, the creators didn’t think about it. The defender is obliged to act on the same level as the device, where the NFC module is used. In other words, if you use a payment system, you don’t have to worry about the security of your payments. If you lose your phone, or if it is stolen, you will be left behind if you have not set it to unlock and would like a minimum level of security, for example, a pattern key, a finger scanner or a PIN code.

Of course, the importance of NFC technology compared to other drone-free solutions is due to the fact that the technology is essentially a script, similar to Bluetooth, which clearly states that you are responsible for accepting and deleting data. Or you can use headphones and other devices . With NFC, you can create various methods yourself, which will be implemented with the help of software. In short, let your imagination run wild and you can create a lot of great things.

Before speaking, I didn’t even say that the NFC function was created on the basis RFID Identification. These are the so-called tags that allow you to automatically identify devices from the selected radio signal. This ability allows you to communicate with both active devices (which operate on batteries) and passive ones (which do not require life).

What is the peculiarity of technology and where it gets stuck?

When it comes to smartphones, there are a number of options for using this type of device:

• Vikoristannya as a payment system (linking credit cards, gift cards and discount cards);
• Transferring data between two devices (I guess, stand at least 10 cm between the devices);
• Vykoristannya as identification of a koristuvach;
• Connected to Bluetooth technology for data transfer;
• Reading RFID tags to extract any information, for example, from boards is overwhelming.

As has already been said, NFC is most often used in smartphones and tablets on iOS. On the other hand, we are practically never separated from our phone, so the introduction of droneless technology was aimed at us first on mobile devices.

In the future, NFC technology will be embedded not only in mobile phones, but also in electronic keys, with a unique identifier, which may not be detailed, when purchasing air tickets, but also in other tickets. and other options.

Door locks and handles

Before speaking, you no longer need to use the key drive to open the doors and even the handle, which incorporates high-frequency drone-free communication technology. For any device (for example, a telephone), you can enter a special tag that opens the door at the time of day. This can be found in Chinese online stores like Aliexpress.

It’s amazing that this is what intelligent castles are called. It’s not just the key opening that stinks, but the activation of the NFC module. You can send notifications to your phone about the times when you open doors (or want to work), as well as when you knock. The lock can be knitted along the edge and at a distance from it. You can send electronic keys with stamps and distribute them to all family members or tell your friends.

NFC ring, what it is and how to use it

As has already been said, if there is any communication with the NFC module, you can record almost any information. For example, you have a special ring. For help, you can transfer your contact information and do not need to carry any cards with you. You can also use vikorism to open the locks themselves.

If there is no electricity in the cabin (and the lock is powered by new or batteries), then the doors can be opened with a key. In this case, be sure to play it safe and always carry the key with you when you go.

Contactless payment

I have already written about this type of highly valuable technology. Almost all places in Russia would like to have one store, or an ATM or a reader that allows you to use it. The card needs to be connected to a program such as Android Pay or Samsung Pay.

Payment for travel

To pay for the metro or go through the turnstile, the same NFC will help you. To pay, you will need a special SIM card supported by this technology. Most likely, most operators will support this, or rather clarify it.

You will find that you can use NFC in jewelry, and you can use it in tattoos, for example, to unlock your smartphone.

New on NFC Forum

At the same time, with the development of the foundations and the forum, developers are trying to push the technology into various everyday solutions, including smartphones, especially.

On the resource you can find the necessary information about NFC and new developments related to the variety of standards in certain devices.

How to be safe with NFC-equipped devices

Various methods of unauthorized access to data via NFC have been discovered more than once. For example, in 2012, an exploit was created that allows you to remove a bad code from your smartphone and deny access to everything you own, including your device.

Since the attacker has the necessary antennas to be able to listen to a person via NFC, of ​​course, with sufficient skill, you can be able to listen on a distance of a few meters maximum. What is important is the fact that a device that allows you to live with energy is easier to listen to and is a less passive option.

Through experiments, it was discovered that the connections between the devices were disrupted by jamming the signal. The radio signal, apparently, is very easy to detect, and the RFID module is very sensitive.

Why can't you use Bluetooth for this operation?

Bluetooth and NFC have the advantage of having a large range, through which the signal is easy to penetrate, as well as a short access time. NFC communicates with the Mitjevo device.

NFC - which phones have it and how to remove it

I'll show it on an Android phone. When purchasing, you melodiously read the characteristics of the smartphone, and, melodiously, there was a row “NFC support”. If you don’t remember, you can marvel at the adjustments of the system.

To start, swipe the animal down the screen to open the notification shade. It is entirely possible that you will get the NFC option there.

If the curtain has no functions, go to settings. I have Android 7.1.2 with the LineageOS shell, so I’ll show him some examples. In separate "Bezrotovy merezhi" press the button "More".

We went to the section where the NFC section is displayed, where you can click it. There is also the Android Beam function, which allows you to exchange data between devices and contactless payment, where you can select the main payment method.

How to get tags from an Android device

To get started, you need to know NFC tags. They can be used to run any program for Android. For example, you are sitting behind a bench, and it is not easy for you to quickly search for the required program and get out of the way. Here you can come to the rescue by giving your smartphone the program to start.

To record the necessary data in a tag, you need to download the program NFC ReTAG. Next, scan the tag, and then select the program you want to launch when you bring it to your smartphone.

How to transfer NFC files

Now go to the phone where you want to send the file and check. In fact, this option for transmitting data is heavily compromised by Bluetooth or Wi-Fi, but if you need to transfer any sensitive data, then a small radius of action and minimal reliability of transfer can be ensured.

In addition to standard file transfer using Android Beam, you can transfer:

• Open the message in your browser;
• Data from Google Maps (singing route and place);
• Contacts – abused without a photo;
• Programs from Google - overpowering;
• Whether there are types of files - from text to media.

Creation of marks

To create marks, you will need a blank, a form factor that can be customized to your liking. Original round marks can be purchased both in Russia and on the Internet, for example, on Aliexpress for 80 rubles.

Now you can install the program on your smartphone (do we really need to write down the information on the tag?). I can propagate TagInfo and TagWriter.

Another utility can write the required data to the tag, which we will need today. Persha reads the information. You can record everything that is possible, but if the fragments of the mark can be even small (read in bytes), then the actions given, the type of contacts, will not always be able to be recorded. More precisely, the contact itself will be recorded, and the photo axis will be linked to something else. In upcoming articles, I will show you how to create an NFC tag using the specified program.

So now you all know what NFC is, in which phones it is and will soon become a problem. In everyday life there can be a lot of help. As far as nutrition goes, be sure to sign up in the comments.

The current mobile industry is promoting consumer smartphones in any price category with non-invasive technologies that people really need. However, not everyone knows about NFC technology, and even more are those who don’t use it. Aletsey module is super-important and strong.

What is the essence of “near field” technology?

Most commonly it is called “near field communication” - a literal interpretation of the English phrase “near field communication” and NFC for short. This technology is based on the drone-free transfer of information. Because the operating radius is limited, data transmission from device to device takes place on a stand that does not exceed 10 cm.

As they say, in simple terms, using additional NFC gadgets, you can exchange data contactlessly. Golovne, so that at this moment the stench was one of a kind in the nearby vicinity.

NFC is an extension of the ISO 14443 standard for contactless cards. This technology combines the smart card and reader interface into one device. Operates at an operating frequency of 13.56 MHz. Maintains the minimum hour required to establish a connection between the devices to be exchanged - no more than 0.1 parts of a second.

Physical components that support NFC technology are even more compact in size and have low energy consumption. Therefore, the “near field” is actively stagnating in modest-sized mobile devices.

To ensure that homeowners don’t have any problems with the use of NFC (not everyone understands which side to use the gadget for the technology to work), the chip’s installation is often indicated on the device with a special sticker.

How can you figure out what NFC your gadget has?

For small-sized devices, communication is favored in many gadgets, and not least in phones: for example, in payment terminals; This applies to cards designated for travel expenses; present in banking plastic. Nowadays, they began to produce household appliances equipped with “near field” technology, such as Smart refrigerators.

How can you understand that NFC, for example, is available on a mobile phone?

Before we go, take a look at the gadget itself. Often the transmitters on the body of the equipment remove the indentation from the appearance of the emblem, which indicates the antenna. A similar icon will appear in the drop-down menu of your mobile phone.

You can also look into the settings by selecting the “Dartless Measures” section. Then you need to click on “More” - and since there is an indication of NFC availability, then put a check mark next to its icon to activate it.

NFC Sphere

Today there are 3 main areas where “near field communication” is required:

1. Non-contact procedures. To do this, you need to link a bank card to your smartphone, and then touch the gadget to the payment terminal to write off pennies. As a result, there will be no need to carry payment plastic with you. In addition, such a payment method is considered one of the most secure, since NFC has such a small range of action. Well, evil-doers won’t be able to intercept the signal.

It’s very easy to activate this technology for rozrakhunki:

· You probably have a bank card that supports the “paypass” mode;

· It is necessary to install an additional deposit with the issuing bank;

· After this, you need to go to the “Special Account” and select the “NFC” item there;

3. Exchange of information. To implement this function, you must install a special add-on called Android Beam. It is possible to transfer different files from one device to another. Please remember that transmission speed via NFC is low. Therefore, it is better to overpower the message, and not the files themselves.

4. Reading the marks. For this purpose it is necessary to install a special add-on. Yogo can be found on the Play Market. As a result, customers will be able to recognize, for example, a warehouse of food products and the term of their accessory, only by bringing a gadget with NFC to read the barcode of goods.

NFC tags are also sold in a variety of accessories. They can be placed on the table, glued to various objects, or hung on a key ring. Such tags are used to manage the “smart wake-up call”. You can record information on NFC tags using additional special programs. And with additional help, you can turn on your smartphone and automatically switch to the robotic mode.

For example, the mark may be on the dashboard of a car. In this case, your smartphone will be connected to Bluetooth, after which you will connect with your phone using an additional wireless headset. And it’s not obligatory, but only one action is programmed. If you turn on Bluetooth, you can connect to your favorite radio station, and the GPS navigator will start. In a word, everything is left to the imagination of the koristuvach!

Regardless of the restrictions in the business sector, NFC technology has proven to be very useful. And therefore, they are now actively promoting even budget gadgets, gradually expanding their list.

For additional technologyNFC you can not only transfer data from one card to another, but also pay for purchases(for example, stocking up on food items at a supermarket).

Decryption is simple - NearFieldCommunication, which, when translated verbatim into Russian language, means communication of the near field and connections in the nearest space.

This technology was first used for fast contactless payment. In addition, NFC replaces a plastic bank card and Bluetooth and integrates them into one system, which adds a practical input for the local user. Do you want to simplify the process of paying for purchases and transferring files? Let's figure out how to find out what NFC is on your phone, tablet or laptop.

The history of the emergence of telephone technology

It’s important that the technology is remarkably young. Their appearance dates back to 2004: during this period, three famous companies Nokia, Philipps and Sony organized the “NFC Forum”, and three years later they integrated the first NFC tags into Nokia phones.

Smartphone models that support NFC

Please note that not all phones support this transmission technology. It appears that NFC is supported in such devices as:

• Apple iPhone (starting with 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).

We check the accessory for NFC functionality

Who would like to try the technology in practice, but don’t know what this capability is on your device? Let's check it out.

To do this, carefully open the back cover of the smartphone or tablet so that it can be taken out without damage and inspect the battery of the gadget.

For the presence of NFC, you will learn this abbreviation there. If the cover of the phone/tablet is not removed, the corresponding icon or abbreviation will be placed on the outside side.

If for some reason you are unable or unable to remove the cover, you can find out about this method of communication by setting up your device.

Find the “Bezrotovye Merzhi” tab, then “More...” and if NFC is on the device, then there will definitely be a clear point.

How it looks, marvel at the photo more or less video instructions about those yak verify correctlyNFC on the phone:

NFC activation

If you have found it on your device, you must activate access to the technologyNFC. You can do this like this:

1. go to the “Adjustment” section and then “Dartless measures”, “More...”, where previously you could go to NFC visibility;
2. confirm the instructions “Allow the exchange of data when there is too much > device name > with others”;
3. Android Beam is immediately activated on your Android smartphone. If something has happened, press on it and select “So”, so as not to destroy the system;

NFC can be activated in the quick menu, in the same place where Wi-fi is turned on. Avoid using NFC tags.

Watch the video for more details:

What should you do if your device does not support NFC?

Don’t worry if you don’t know the built-in function and how to connect NFC to your device. In order to make the most of it, the panel cover on the gate and the opening for the SIM card on your smartphone/tablet are important. . Installing NFC is not at all difficult.

Installation of NFC module

The optimal solution is to install a special module – a new communication device. It’s very practical with all smartphones, it’s just that the old one gives access to NFC without buying a new phone.

Types of modules and methods of their implementation

Main types: chips, SIM cards, external devices, stickers. The rest of them are of two types: passive - which do not allow the ability to exchange data, and active ones for transmission use Bluetooth and Wi-fi communication channels, which significantly promotes energy saving.

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

The most popular are:

• NFC SIM card. The download is available for purchase from most mobile operators. You can find out about the presence of such a SIM at the call center. You just need to install the ready-made card on your phone or tablet. This type of module is the most accessible and easiest to install.
• NFC antenna. Another method for which you need to add an NFC antenna. You can get a connection from the salon. Next, the antenna is connected to the SIM card and is inserted into the device.

If you have already downloaded, install the module just finish it safely : You do not need to download additional programs or programs. However, these services do not replace the Android Pay add-on, but rather any number of other functions.

How to use an NFC tag

The NFC tag is a miniature, chip-shaped device that can be attached almost anywhere: starting with your phone and ending with your home!

We will not indulge in such radical methods, but just note that you can put contacts, settings, URLs, other data and commands in the chip. The building tag supports all gadgets.

Data exchange via NFC

The technology can be used to transfer files.

To transfer data you need to complete the following steps:

1. Please confirm that you have activated NFC and Android Beam;
2. remove the blocking device, get out of sleep mode;
3. check the identified devices one by one;
4. connect;
5. enable data transfer between devices;
6. Finally, a specific sound signal sounds.

However, not all types of files can be transferred this way. For example, it is impossible to send programs.

Advantages and disadvantages of NFC

The main advantages are:

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

Varto see and minuses:

• the radius is obviously small;
• Not all devices have an NFC chip.

In addition, the Swedes have now discovered simple ways to test your device’s ability to transmit information and interact with other technical means through Near Field Communication. By following the simple instructions of this article, you can also find out on your own what technology is in your smartphone, integrate NFC with your phone and transfer the required files at high speed.

Today's smartphones are increasingly introducing three new NFC options in their specifications and descriptions. However, it is rare that scant explanations are given about what the technology of shotless linking is. Let's put everything in order and take a closer look at NFC on the phone, what is it?

What is NFC?

NFC technologies appeared in the early 2000s, with Philips and Sony companies being the pioneers in this field. The first activities were inconsistent with each other, and the fragments were carried out independently of each other. The companies pooled their strengths and announced their technology until 2004.

The main significance of the technology is contactless cards for a wide variety of purposes, combining a variety of services into a single way to access them. Paying for public transport fares, payment transactions, electronic passes, or, for example, sending advertisements are the use of NFC technology.

The name sounds like Near Field Coomunication, which in Russian is translated as: “Near field communication.” What do you need NFC for your phone? It is not possible to mix this connection method with Bluetooth or Wi-Fi. Its communication speed is close to 400 kbit/s, and its range is less than 10 centimeters. Use safe technology.

Scammers will not be able to use your NFC tag on their own due to the short range of reception. You can safely conduct financial transactions by confirming your actions with their help, without worrying about the security of your personal data. Your phone now needs NFC, we'll tell you later.

Nokia 6131, released in 2006, became revolutionary. This phone was the first of its kind to use NFC. Samsung has pioneered NFC in Android phones, including the Samsung Nexus S in 2010, and optionally in the Galaxy Note and Galaxy S2 in 2011. With this NFC function on the phone, users were denied access to many basic functions, which we will describe later.

Unfortunately, in 2017, most of the cheapest smartphones do not have the ability to communicate via NFC, which allows for expansion. And NFC tags can be installed in small devices to implement various functions.

It’s not just Samsung that is using the technology, but Apple, Meizu, and Xiaomi also use NFC on their phones.

Possibilities NFC

Let us first note that you can use NFC communications to pay for items and purchases. For this purpose, Google launched the Wallet program. Many banks have supported the idea of ​​contactless payment by phone. NFC adapters are installed in terminals for unprepared distribution in stores and cafes. You can pay for your mobile phone with your phone. To do this, you need to push the back cover of the phone up to the mark on the terminal, tick a few seconds, and your data will be read, and payment will be made.

In addition, if you use NFC on your phone as a payment method, you can exchange data between devices. It was said that the speed of such a connection is very low in today's world - close to 400 kbps. Therefore, a technology for combining methods of binding was invented. The additional NFC device is “recognized” one by one, and a connection is established, and then file transfer takes place via Bluetooth or Wi-Fi direct. This ensures the possibility of exchange at high speed, and the connection is possible only through the back covers of smartphones.

In this case, a robot with NFC tags can only be found in both phones. This is how Android Beam technology works and its analogue for Samsung Sbeam is an excellent way to transfer data to an Android phone.

Also, using additional tags, you can quickly transfer contacts from your Android to another user.

How NFC works on a phone

The system of wireless communication in NFC works on the principle of reversal of electromagnetic circuits. The circuit guesses the classic detector trick.

NFC tags come in two types:

1. They are active – they can be used to transmit additional signals and signals.
2. Passive - they operate without control and contain specific permanent information, i.e. they can transmit a signal beyond the programming.

Let's take a look at the link between two phones.

- a coil and a condenser, which is a flammable circuit; The LED detects the external magnetic field and sends this signal to the device - this is the circuit of the NFC tag.

There are two devices with such marks, when you bring them up one by one, the mark of one of them points its vibrations at the other mark - they are detected and the other device matches the first. In this way, the process of data exchange, identification, etc. is repeated cyclically.

This is the basic principle of the NFC system on the phone.

Some phones have NFC

This technology is being used by an increasing number of smartphones. Phones that support NFC are no longer uncommon, and are becoming more common not only among well-known manufacturers, but also among Chinese “nonames.” Especially after the number of terminals for paying by phone began to grow, people all over the world began to use such models. As you can see from the installation of a finger scanner on the phone, NFC repeats its share - initially this function was not available on the TOP models of popular brands and was considered extraordinary. Later, fingerprint sensors began to be sold on phones for up to 100 dollars.

Which phones support NFC? Among popular brands, the latest models 2016-17 have a module in Samsung phones of the seventh generation (S7, J7, A7), and in younger models (J5 and similar) this function is also strengthened.

Sony has most of its current models equipped with an NFC module, a short list of them:

• Xperia XZ;
• Xperia L1;
• Xperia XZ premium;
• Xperia Z5 and many others.

The list, among others, includes selections from models of different price ranges. And among the cheapest phone models with the NFC function are:

1. Theft of Blackview BV6000S.
2. Suvora Nokia 3 Dual Sim.
3. Vitrimana Sony Xperia L1.

Let's look at the prices of phones that have NFC.

Flagship models of phones with NFC – prices

We'll take a look at the most popular models of slim, stylish and smart phones powered by NFC technology 2017. Let's finish:

1. Samsung galaxy S. Its price at the time of writing is approximately 650-700 dollars. Display – 5.5, 8-core processor, 32 GB of memory and 4 RAM. The metal body provides a modern look and additional protection for the interior of the device. It runs on an 8-core Samsung processor with a clock frequency of 2.3 GHz.
2. Sony Xperia XZ Premium– the cost is 750 dollars, which is a little more expensive for Samsung. It has twice as much memory - 64 gigabytes and a thicker camera of 19 MP, versus 12. The processor from Qualcomm has 8 cores that operate at a frequency of 2.45 GHz.
3. LG H870G6 The cost is 750 dollars, but the display is larger – 5.7 inches. Processor from Qualcomm 4-core 2.35 GHz. 64 GB for saving data and 4 RAM ensure stable operation, and a 13-megapixel wide-angle camera ensures the clarity of photographs.
4. XIAOMI Mi6 6/128GB Costs 600 dollars, its powerful 8-core Qualcomm processor at 2.45 GHz, 6 GB of RAM and 128 GB of memory - turns your smartphone into a useful multimedia center for games and other add-ons.
5. samsung galaxy a7– the cheapest one in this category costs less than 400 dollars, and that’s why it’s popular. The latest Samsung processor, albeit larger than the latest models, has 8 cores and a frequency of only 1.8 GHz, coupled with 3 GB of RAM and 32 GB of permanent memory, making it a wonderful phone for Internet. Until then, there is a problem with drinking and water, a bad camera and a bad car.

A list of smartphones with NFC is available with popular phones priced at over 20,000. You shouldn’t choose to buy an expensive phone, either for financial reasons or any other. Is it cheaper?

Cheap phones with NFC, priced up to 15,000

As was already said earlier, phones with near-field communication technology have filled almost all price segments, including budget phones. We invite you to get acquainted with phones in the segment up to 15,000 that support NFC, and their prices.

1. Nokia 5 Dual Sim- costs about 250 dollars, this one has a normal, but not so current processor - Snapdragon 430, 8 cores with an operating frequency of 1.4 GHz, running on Android. A 13 MP camera allows you to take good, clear photos.
2. Motorola E Plus XT1771- 200 dollars, inexpensive 4-core processor MTK 6737, advanced indicators of autonomy - a dedicated phone for everyday use by intractable users.
3. Sony Xperia X- A decent camera background for $250, a good lens and a 23 MP matrix - make your photos clear and sharp. A 6-core Snapdragon 650 and 3 GB of RAM allow you to play current games.

Three new models of phones with NFC, which you can easily buy at any time.

Which Chinese phone with NFC should I buy?

Inexpensive phones with additional NFC can be bought for literally pennies. Chinese telephones with near-field communication can be exchanged with China, thereby providing wicked protection. The now popular Xiaomi brand releases models in different budgets, ranging from cheap to expensive. How does Xiaomi support NFC? In fact, there are a lot of them, so pay attention to the line: Mi4, Mi5, Mi6 and others - they all have this function.

The cheapest phone with NFC is AGM A8, waterproof and runs on Android 7 and a 4-core MSM8916 - it can be purchased in the range of 150-200 dollars.

The proposition is cheap, a phone with NFC is the Bluboo Picasso 4g, its price is about 100 dollars. It has a budget processor MTK6735 and Android 6.0; The modest filling is suitable for watching videos on YouTube and surfing social media – an ideal option if you don’t have to spend a pretty penny on a smartphone.

How can you find out if your phone has NFC?

It is possible that your smartphone is experiencing this corrosive problem. To find out what NFC is in your phone, you can remove the battery cover - there is a similar symbol on the sticker. If you haven't checked the Near field Communication inscription on the battery, what should you do? How can I find out what my phone supports NFC?

Go to the phone in this way: setup - bezdartovy z'yazok (z'ednannya). In this menu there is an NFC item - you need to turn it on, Android Beam may be automatically activated. Otherwise, you simply do not have these functions, otherwise you can solve this problem. Now you know how to check what's in your NFC phone, let's figure out how to install it in Android.

What works, since there is no NFC – NFC antennas and modules for the phone

Don't worry if you don't know the NFC function on your phone. The design of an NFC antenna for your phone is a foreign concept, don’t be fooled, it’s a simple solution. Install the NFC module. You just need to find a SIM card with an NFC chip and install it in your phone.

This NFC SIM card can be installed to make payments for an additional phone.

Another way to install an NFC module on your phone is to have a full-fledged NFC antenna. This is pasted onto the SIM card, and the other half is placed under the cover of the smartphone. This re-equipment adds even more possibilities to work with this technology.

Now you know what to do because there is no NFC!

How to turn on and use nfc?

If you have configured the phone menu, there is a group of parameters “Dartless ranges”, click “More” - the list of parameters will open. The NFC item may be disabled; you will need to switch the switch on the screen to the “Disabled” position. NFC setup on your phone is complete.

To set up an NFC phone for payment, you need to use the Visa QIWI Wallet program, and connect the account to your account via SMS, the program checks the availability of the module on your phone, and it indicates that it is suitable for him.

Visnovok

Modern technologies will not only make our lives easier, but also speed up our lives and make them more comfortable. This technology allows you not only to save time, but also to work even more safely.

The safety of the connection is guaranteed by the near-field connection, so that you practically stick the marks together during the transmission of data. Programs that use NFC technology allow you to use the gadget not only for payment, but also to change phone modes when you read the tag. You can place tags in your car, home, bedroom, and configure which parameters will respond to which tag - this essentially automates your device.

NFC stands for Near Field Communication or literally “near field communication”. This technology is based on the transmission of data between devices at a distance of up to 10 cm. The connection is supported by the additional induction of a magnetic field.

NFC can be used in active and passive modes. For the first one, it is necessary that the device be offended and lively, but for the other, one thing is enough. In the end, one of the devices removes its working force from the electromagnetic region of the other.

The NFC chip itself can be compact in size, allowing it to be installed in smartphones, audio speakers, tablets and other mobile gadgets.

Why is NFC useful?

The advanced NFC technology has a very high installation speed between devices. In this case, the speed of data transmission in the active connection mode is low. Moreover, in smartphones NFC is used only for transferring contacts, messages, notes, as well as coordinates on the map.

When transferring large files, the technology is limited to connecting devices, and instead is used via Bluetooth or Wi-Fi. It is advisable to transfer simple videos and documents through the “Upload” function.

You can find out exactly how to install the chip's antennas in the instructions for the device. However, in most cases the stench is located on the back of the body. Therefore, when connecting via NFC, smartphones need to be fitted with back panels one by one.

The passive mode of communication can be used to read information from the programming of NFC chips or so-called tags. The Vlasny Dzherel vitality does not smell, but the activation resembles the electromagnetic field of the reader device.

The main purpose of the tags is to provide additional information about the product or any other product. For some retail outlets, NFC tags will now replace barcodes. By holding down the smartphone, the buyer can view detailed information, terms of use and savings.

Labels can also be set to automate various actions on a smartphone - turning on add-ons, changing the sound profile, sending notifications, and so on. For example, you can program a tag to launch your navigator and attach it to your car. As soon as you place your smartphone on it, the gadget will start automatically.

Tags are programmed through special programs on a smartphone, such as NFC Tools.

Gadgets with NFC can be used to emulate smart cards, which can be used as a pass, a key or a card. However, with the arrival of Android Pay and Samsung Pay payment systems in Russia, the main purpose of the NFC chip in a smartphone has become the emulation of bank cards for contactless payments.

To pay for goods using NFC, simply bring your smartphone to the terminal at the checkout. The main thing is to first link your bank card to the payment system available for your smartphone.

The largest number of devices is Android Pay, which, while being replaced by similar services from Apple and Samsung, is not tailored to the device of the singer. However, you can use any of these payment systems without fear or risk.

However, at the time of payment, the card number is not transmitted to the terminal itself. Instead, it is called a token - an encrypted digital identifier that is generated automatically when the card is activated. The wine itself is considered as the main requisite.

How secure is NFC?

NFC devices can simultaneously receive and transmit data, which allows them to detect if the received signal does not match the transmitted one.

The risk of your data being overrun is very small, especially with the minimum radius of this technology. The same Bluetooth, which operates within tens of meters, has a significant impact on external communication.

There are also payment details: generating a token for contactless payment will not allow criminals to deny access. The very fact that the encrypted identifier was stolen seems unrealistic.

In addition, before contactless payment, confirmation is required via a fingerprint reader, password or personal scan. Without which the purchase cannot be made. However, if a smartphone is stolen, no one can quickly use it as a payment instrument.

If this technology is less expensive than the flagship, you can immediately buy a smartphone with NFC for less than 10,000 rubles. There is a need for Android devices. Among the most accessible ones are Nokia 3, Samsung Galaxy J5, Motorola Moto G5s.

In the Apple ecosystem, the cheapest smartphone with Apple Pay support is the iPhone SE, which today costs a little less than 20,000 rubles. All the more expensive models, starting with the iPhone 6, also lose their NFC chip.

If you don’t know what NFC your Android smartphone has, you can check by searching. Consider the functions associated with this technology that are available in the sections connected to or without drones. Also, the NFC icon may be present in the list of launcher icons in the browser window.
