What is NFC in a smartphone. News and analytical portal "electronics time". Is there NFC on my mobile phone?

NFC or Near field communication (translated as “near contactless communication”) is a type of short-range wireless communication that allows you to exchange data between devices. The system was first announced back in 2004, but has only become truly popular now. It can be found in many smartphones.

If we talk in simple language, then thanks to NFC you can quickly connect with other devices that support this function. In this case, no logins or passwords are required. Another important feature of NFC is the ability to transmit data at close range (range of up to 20 cm).

Comparison with Bluetooth

NFC is often compared to another wireless technology, Bluetooth. The comparison is quite logical, since both technologies began to be used in phones and smartphones relatively recently, and they are also very similar. However, NFC has one extremely important feature - it is much more a short time to establish a connection. An NFC connection between devices is established immediately - to be precise, we're talking about less than about one tenth of a second.

NFC has another important advantage - the ability to work with devices that are not equipped with a power source. These include, for example, bank card or a switched off phone.

However, in some other parameters, Bluetooth technology is ahead of NFC. For example, this includes a higher data transfer speed (24 Mbaud versus only 424 kbaud), as well as a significantly larger range. The latter cannot be considered a clear advantage, since in a crowded space NFC technology with a shorter range provides greater security.

Where is NFC used?

Currently, NFC is used primarily in smartphones; the technology can also increasingly be found in tablets.

NFC can be used as mobile payments (for example, when passing through a turnstile, fares are written off), for reading various tags from information boards, for exchanging and reading other information.

The technology's coverage is expected to expand over the next few years. Thus, with the help of NFC in his smartphone, the user will be able to make most of his purchases on the Internet, use NFC as an ID card, open and close his car, initialize communication with other types of wireless connection and so on.

In general, NFC in the future will be able to replace documents, bank cards, and much more. All that's left to do is wait.

About security

There is nothing to worry about for now, because the quality payment system We don't use NFC. But, most likely, it is only a matter of time and then the situation may change radically.

In 2012, experts presented an exploit that was transmitted via an NFC connection, after which full control was gained over the receiving device. This means that the device owner's funds could be at risk. By the way, NFC, despite its very short range, does not guarantee the security of the connection.

Additionally, the RF signal could theoretically be intercepted by an antenna. True, the distance should be very small - no more than a few meters, not to mention the fact that listening is influenced by many additional parameters.

Does my smartphone have NFC?

To find out whether this technology is available on your device, you can refer to the characteristics of the device. In addition, in the menu you can find additional subsections for setting up NFC in the wireless networks section. Finally, some models have the NFC logo, which can usually be seen engraved on the battery.

Modern smartphones are very functional and contain many different technologies, which are certainly useful and necessary, but are not always clear to the average user. The same applies to Near field communication. In the characteristics of a smartphone, the technology is indicated by the abbreviationNFC, what is it in the phone?Few people know, so when buying a new smartphone they often doubt whether such a function is really necessary. Let's talk about this in more detail and figure out what this opportunity is and how it will be useful to the owner.

So, NFC is a high-frequency wireless communication module with a limited range. In order to prevent data interception, the radius does not exceed 10 centimeters, and more often than not, even less. To transfer information from one device to another, you need to bring their sensors as close as possible.

The technology operates at high speed (connection time between two sensors is no more than 0.1 seconds). In general, the work is based on radio frequency identification; data from transponders is transmitted from one gadget to another via radio signals.

Today, such a module is found mainly in gadgets on the Android platform, and it is being implemented not only in expensive devices, but also in models in the mid-price category. However, modules are often found on other device models, but their capabilities are often limited to one function. The data on the transponders can be different, thanks to which the phone can act in a variety of roles. This is very convenient, primarily due to the fact that the gadget has long become an integral part of a person’s life and accompanies him everywhere.

How can you use a phone with an NFC module?

The technology is still gaining popularity and is by no means widespread. That's why few people know todayNFC, what is it in the phone?. Nevertheless, even in small settlements remote from the central regions there are examples of the use of the module.

As mentioned above, the transponder can contain various information and assign different roles to the smartphone. Here are some of the most familiar and common use cases.

Thus, it can act as a payment instrument, a means of user identification, a key for electronic locks, a bonus card, a travel ticket for any type of transport. The technology is actively used in areas where greater security and confidentiality of data transmission is needed. You can also often find examples of using the module in the service and entertainment sectors.

How NFC works

So, NFC, what is it in the phone?we figured it out. Let's try to figure out the operating principle of this development. Some users know that the technology can also manifest itself on passive devices, that is, data exchange does not necessarily require a connection to an active power source.

This is due to the fact that the technology is based on electromagnetic induction. That is, the reader transmitter at a frequency of 13.56 MHz at permanent basis emits a sinusoidal signal. The sensor is also equipped with an antenna and when the distance between the two elements becomes sufficient for the technology to work, a magnetic field is created by an alternating current in the coil of the reading element. After this, a current appears in the second coil; a tiny charge is enough for NFC to operate, so it does not require an additional power source.

Modern smartphones contain an NFC antenna under the back cover. And its location, as mentioned earlier, is marked with a special icon. This location is very convenient, since an antenna located deeper can complicate the data exchange process.

What is the advantage of NFC over other wireless communication modules?

Active smartphone users know that the gadget is equipped with several technologies at once. wireless transmission data, so why do we need another one if there are already others. These are, of course, the familiar and familiar Bluetooth and .

However, NFC has a lot of advantages over its counterparts, which mainly ensure the security of data transmission and the absence of the possibility of interception of information.

• First of all, this is the shortest possible connection time. In one tenth of a second, complete data exchange occurs.
• The limited range makes the data transmission method more secure. The technology, according to the developers, operates within a radius of 10 centimeters; in practice, it is significantly reduced.

The data transfer speed is significantly lower than that of Bluetooth, however, this does not spoil the overall impression of the development. In general, NFC is a very reliable and necessary transmission technology, precisely in those areas where it has found application.

To find out if your smartphone supports this technology You can look for the corresponding inscription (Near field communication) on the gadget’s battery or the corporate logo on the back of the device. The module must be present in the smartphone settings, where you can activate it or, conversely, turn it off. In addition, you can clarify the information in the accompanying documents for the phone. To use the technology, you will need to download additional applications, for example, to use your smartphone as a means of payment, you will need Google Pay or Apple Pay.

Initially, Near Field Communication technology ( NFC) has gained maximum popularity as a technology for making contactless payments. You can use a smart card with a built-in NFC chip as a travel card on public transport, as a payment card in retail establishments, as a “smart” business card or as a contactless key card.

However, recently, this technology is increasingly used in devices such as smartphones and tablets: almost all major manufacturers have begun to equip their mid- and high-end models with NFC adapters.

What is NFC?

If we translate the name of the Near Field Communication technology from English, we get the phrase “near field communication”, which can be deciphered in ordinary language as wireless connection over short distances. Thus, we see that two NFC-enabled devices can communicate with each other when they are nearby. And indeed, the “range” of NFC is only a few centimeters.

IN mobile devices ah NFC technology can be used for various purposes. You can, for example, turn your phone into a virtual bank card, or use it as a pass to a swimming pool or to a business. You can also quickly exchange files and links, and even, using special applications, read and write information to programmable NFC tags or NFC smart cards.

In the operating room Android system, NFC support appeared in Android versions 4.0 Ice Cream Sandwich - Its built-in Beam feature allows you to share files between devices.

Why do you need NFC if you already have Bluetooth?

As you remember, NFC is most often used when paying for various goods or services, and in this case Bluetooth is not entirely suitable. Firstly, due to its large range (there is a possibility of interception of your payment data). And secondly, the connection between two NFC devices, unlike Bluetooth, occurs almost instantly.

Does your device support NFC?

Not all phones and tablets have NFC adapters. Does your tablet support NFC? How to check its availability?

Some manufacturers, such as Samsung, place the Near Field Communication message directly on the battery of their smartphones, while others, such as Sony, place the NFC logo on the device.

However, the easiest way to check the presence of an NFC adapter in your phone or tablet is through its settings menu:

Go to the settings menu of your Android device

In the Wireless Networks section, click More...

Here you should see NFC settings items:

NFC activation

If your tablet or phone has an NFC adapter, you need to allow it to be used to exchange data between other NFC devices.

Go to Settings -> Wireless & networks -> More...

Check the box next to "Allow data exchange when combining the tablet with another device"

This will automatically turn on Android Beam.

If Android Beam doesn't turn on automatically, simply tap on it and select Yes to turn it on.

When Android Beam is disabled, it limits the ability to share NFC data between smartphones or tablets.

Sharing data using NFC

Once you have activated NFC, you can use it to transfer data. For successful data exchange between tablets and phones, pay attention to the following:

Both the sending and receiving devices must have NFC enabled and Android Beam enabled.

None of the devices should be in sleep mode or have a locked screen.

When you bring the two devices close enough to each other, you will hear sound signal, indicating that the devices have discovered each other.

Do not separate the devices until the data transfer is complete and you hear a success signal.

Data transfer via NFC

Place the backs of the devices facing each other.

Wait until confirmation appears that both devices have detected each other and the message “tap to transfer data” appears on the sender’s screen:

Click on the screen and data transfer will begin:

You will hear a sound confirmation both at the beginning and at the end of the data transfer.

Application sharing

With NFC you can't share APK files. Instead, the sending device sends a link to that app to the other device. Google Play Market, and the recipient opens a page in the Market with an offer to install it.

Sharing web pages

Just as in the previous case, the web page is not transferred from one device to another, but only a link to it is exchanged, which the recipient tablet or phone opens in its web browser.

Exchange YouTube video

Again, when sharing a YouTube video, the file itself is not transferred - the second device will simply open the same video on the YouTube website.

Using NFC tags.

In addition to exchanging information between tablets and phones, you can use your device to read (and write) data from NFC tags and smart cards equipped with an NFC chip.

NFC chips are small enough that they can be embedded anywhere - in business cards, bracelets, product labels, stickers, price tags and other items. They can contain information about the person, a URL, product information, and even commands that your phone or tablet should execute when you touch these tags.

To read data from NFC tags (or to write information to them), you will, of course, need a special application.

For example, using the Yandex.Metro program you can find out how many trips are left on your disposable Moscow Metro card, and the NFC App Launcher program will allow you to program your phone or tablet to perform certain actions by placing the corresponding information in the NFC tag.

Conclusion

Most of the modern Android phones and tablets are already equipped with NFC adapters, but so far this function is in little demand and its use is still limited, mainly by the ability to quickly exchange content and contactless payment for services. However, in the future, NFC may penetrate into all areas of our lives, sometimes even completely unexpected ones.

NFC technology(abbreviation for Near Field Communication) allows you to exchange data between your smartphone and other NFC-enabled Android phones using Android function Beam. The main feature of this technology is its short range (up to 10 cm), allowing contactless data exchange between devices located on the short distances: for example, between the reading terminal and cell phone or a plastic smart card. For example, you can transfer web addresses, map positions, applications from Google Play Market and contacts to other phones running Android OS. Among other things, it is possible to share photos, music and videos between Sony phones Xperia. As a user of a smartphone of this line, I will tell you using his example. Although other companies producing high-tech products are also actively involved in the development and implementation of NFC: Google, Intel, Samsung, Nokia, Visa, MasterCard, Citigroup, Barclaycard and others.

I use NFC in my smartphone for quick synchronization with Sony MDR-1RBT bluetooth headphones or wireless sound system Sony SRSBTM8. If you have never used NFC, you can activate this function on your smartphone and attach your metro pass to see information about it on the smartphone display. In order not to confuse you, it is worth noting that NFC has a significant advantage over Bluetooth - fast time connection setup. That is, instead of the process of “pairing” 2 devices when using Bluetooth, a connection between two NFC devices is established immediately (in less than 1/10 of a second), but data (for example, an audio stream in bluetooth headphones) will still be transmitted via Bluetooth. To avoid the long “pairing” process, NFC is only used to establish connections in wireless technologies such as Bluetooth.

As you already understand, it was not by chance that a mobile phone (smartphone) was chosen as the “carrier” of the NFC chip, since the device is widespread and is always close to its owner. The latest trend in the NFC field has been the parallel development of services based on smart cards and mobile devices:

Both of the above options provide the ability to build a universal NFC ecosystem, where a smart card or smartphone with an integrated NFC chip turns into multi-purpose devices, acting as:

• means of payment (virtual wallet)
• owner identification means
• bonus card
• ticket

The NFC chip can contain large amounts of data, encrypting it if necessary. Currently, NFC solutions are already used in many areas. For example, using this technology, booking and sales are carried out electronic tickets, payment for travel on public transport and car parking, NFC technology is also actively used in the sphere of services and entertainment. By analyzing the capabilities of NFC, we can confidently predict its potential demand in the field of security and access control.

Contactless infrastructure and contactless payments are already quite well developed in the public transport system, and are quickly emerging in other industries. Telecom operators, mobile device manufacturers, the banking sector and other payment systems are increasingly seeking to use contactless payments.

The most common device in the world that can fully unleash the full potential of NFC technology is undoubtedly a mobile phone. In combination with NFC, it is able to combine all the functionality of options and services that the use of smart cards can provide.

Perhaps today the widespread use of NFC seems futuristic, but in the very near future this technology will firmly enter our lives - just like Wi-Fi, Bluetooth, USB.

Into existing functionality Sony smartphones c NFC technology also includes the ability to scan an NFC tag. NFC tags are small programmable information zones that can be used in shopping and advertising areas: built into posters, all kinds of billboards, as well as on product shelves in retail stores. By touching the mark, you can get Additional information: maps, web addresses and trailers.

NFC function activated when two devices supporting this technology come into contact. The maximum reading distance is about 1 cm, which avoids false triggering of the function.

Modern smartphones increasingly contain three new NFC letters in their characteristics and descriptions. At the same time, very rarely are sparse explanations given that this is a wireless communication technology. Let's break it all down and take a closer look at NFC on the phone, what is it?

What is NFC?

NFC technology appeared in the early 2000s; Philips and Sony were pioneers in this area. The first developments were incompatible with each other, since they were carried out independently of each other. The companies joined forces and by 2004 announced their technology.

The main purpose of the technology is contactless cards for multi-purpose use, combining various services in a single way to access them. Paying for travel on public transport, payment transactions, an electronic pass somewhere, or, for example, a link with advertising are vivid examples of the use of NFC technology.

The full name sounds like Near Field Coomunication, which is translated from Russian as: “Near Field Communication.” Why do you need NFC on your phone? This communication method should not be confused with Bluetooth or Wi-fi. Its communication speed reaches about 400 kbit/s, and its range is less than 10 centimeters. This makes the technology safe.

Attackers will not be able to read your NFC tag precisely because of the short reception range. You can safely conduct financial transactions, confirming your actions with its help, without fear for the security of your personal data. We will explain later why NFC is needed on a phone.

Nokia 6131, released in 2006, was revolutionary. This phone was the first of its kind to work with NFC. Samsung used NFC in phones under Android control, namely in 2010 - Samsung Nexus S, in 2011 optionally in Galaxy Note and Galaxy S2. With this NFC feature in the phone, users have access to many useful features, which we will describe later.

Unfortunately, in 2017, the cheapest smartphones do not have NFC capabilities, which will slow down its adoption. And NFC tags can be built into small devices to implement various functions.

Now it’s not only Samsung that uses the technology – Apple, Meizu, and Xiaomi understand what NFC is in a phone.

NFC capabilities

First of all, it is worth noting that you can use NFC communications to pay bills and purchases. For this Google company suggested Wallet app. Many banks have supported the idea of ​​contactless payment by phone. NFC adapters are installed in terminals for cashless payments in stores and cafes. You can pay mobile phone your accounts. To do this, you need to lean the back cover of the phone against the tag on the terminal, wait a few seconds, and your data will be read and the payment will be made.

In addition to using NFC on your phone as a payment method, you can exchange data between devices. It was said above that the speed of such communication is very low by modern standards - about 400 kbit/s. Therefore, a technology for combining communication methods was invented. Using NFC, devices “recognize” each other and a connection occurs, and further file transfer is carried out via Bluetooth or wi-fi direct. This provides the ability to exchange at high speed, and the connection occurs only by touch back covers smartphones.

However, working with NFC tags is only possible if both phones have it. This is how Android Beam technology works and its analogue for Samsung Sbeam is a great way to transfer data to an Android phone.

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

How NFC works on a phone

The wireless communication system in an NFC phone works on the principle of conversion electromagnetic waves. The circuit resembles a classic detector receiver.

NFC tags come in two types:

1. Active - require a source of additional power and control; they can transmit any signals.
2. Passive - operate without power and contain specific, unchanging information, i.e. they can only transmit a pre-programmed signal.

Let's look at the example of communication between two phones.

There is a coil and a capacitor, which constitute an oscillating circuit; the diode detects the external magnetic field and supplies this signal to the reader - this is the NFC tag circuit.

There are two devices with such tags, when you bring them close to each other, the tag of one of them directs its vibrations to the second tag - they are detected and the second device “responds” to the first. In this way, the process of data exchange, identification, etc. is repeated cyclically.

This is a generalized principle of how the NFC system works on a phone.

Which phones have NFC

This technology is being used in more and more smartphones. Phones that support NFC are no longer a rarity, and can be found not only from well-known manufacturers, but also from Chinese “no-name” brands. Especially after the number of terminals for paying by phone began to increase, the demand for such models increased around the world. This is reminiscent of the introduction of a fingerprint scanner on a phone, NFC repeats its fate - initially this function was only on the TOP models of famous brands and was considered extraordinary. But, over time, fingerprint sensors began to be used even in phones costing up to $100.

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

Most of Sony's modern models are equipped with an NFC module, here is a short list of them:

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

The list, by the way, was selected from models of different price ranges. And among the cheapest phone models with NFC function, the following stand out:

1. Protected Blackview BV6000S.
2. Strict Nokia 3 Dual Sim.
3. Aged Sony Xperia L1.

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

Which Chinese phone with NFC should I buy?

Inexpensive phones with NFC support can be bought for literally pennies. Chinese phones with near-field communication, it will be possible to order directly from China, thereby saving a lot of money. The now popular Xiaomi brand produces models in different budgets, ranging from cheap to expensive. Which Xiaomi devices support NFC? In fact, there are quite a few of them, pay attention to the line: Mi4, Mi5, Mi6 and others - they all have this function.

The cheapest rugged phone with NFC is the AGM A8, which is waterproof and runs on Android 7 and a quad-core MSM8916 - it can be bought in the range of $150-200.

There is a cheaper offer, a phone with NFC is the Bluboo Picasso 4g, its price is about $100. It has a budget MTK6735 processor and Android 6.0; the modest filling is suitable for watching videos on YouTube and surfing social networks – perfect option, if you don’t want to spend a pretty penny on a smartphone.

How to find out if your phone has NFC?

Your smartphone may have this useful technology. To find out if your phone has NFC, you can remove the battery cover - there should be a corresponding mark on its sticker. If you don't see the Near field Communication label on your battery, what should you do? How can I tell if my phone supports NFC?

Go to this path on your phone: settings - wireless communications (connections). There should be an NFC item in this menu - you need to turn it on, Android Beam should also be activated automatically. Otherwise, you simply do not have this communication function, but you can solve this problem. Now you know how to check if your phone has NFC, let's figure out how to install it in Android.

What to do if there is no NFC - NFC antennas and modules for your phone

Don't despair if you don't find the NFC feature on your phone. If the design of an NFC antenna for your phone is an alien concept, do not despair, there is a simple solution. Install the NFC module. You just need to find a SIM card with an NFC chip on sale and install it in your phone.

This NFC SIM card can be installed to make payments using your phone.

Another way to install an NFC module in your phone is to equip it with a full-fledged NFC antenna. It is glued to the SIM card, and the other half is placed under the cover of the smartphone. Such re-equipment adds many possibilities for working using this technology.

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

How to enable and use NFC?

In the settings and menu of the phone there is a group of parameters “Wireless networks”, click “More” - the list of parameters will open. The NFC item can be turned off; you need to switch the toggle switch on the screen to the “On” position. The NFC setup on your phone is complete.

To set up an NFC phone for payment, you need to download the Visa QIWI Wallet program, and link the account to your wallet using SMS; the program checks for the presence of a module in your phone, and, if it detects it, offers to agree with it.

Conclusion

Modern technologies not only simplify, but also speed up our lives and make it more comfortable. This technology will not only save time, but also do it very safely.

Connection security is guaranteed by near-field communication because you are in close contact with the tags when transmitting data. Applications 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, configure which parameters will match which tag - this greatly automates your device.
