How to find out if there is a NFS smartphone. NFC on the phone. What is it? Nfc in the phone - what is it

Mobile industry every day more and more fills our lives with a variety of concepts, the meanings of which we often do not understand. As part of the world, which with a crazy speed is fulfilled by various technologies, you do not want, but you have to face all these neural networks, virtual realities, artificial intelligence and other things. Today, for example, you wondered - what is NFC in the phone? So? Let's then understand.

What is NFC?

Near Field Communication is a technology that provides wireless communication at a high level of quality, with a minimal coating of action (about ten centimeters). Thanks to the use of NFC, you can exchange contactless type between two devices located nearby. As an example, you can bring the interaction between the mobile phone or the smart card and the terminal for reading.

NFC technology Based on radio frequency identification (RFID)which is a methodology for identifying objects in authores. In such interaction, a radio signal is used to read and record the data that the transponder stores. In general, it can be said that the NFC technology supports devices both passive and active, and is applied to transmit data using a radio channel.

For example, Sony NFX key rings do not need an additional power source to maintain their activity and performance. Such a process is fully passive.

The history of the appearance of NFC in the phone

The year of the birth of technology as usual is considered to be 2004, when three large concern - Nokia, Philips and Sony were organized the so-called "NFC Forum". The organization was supposed to serve when developing a common interface aimed at interacting devices between sobody with their contact.

Due to the fact that the technology has evolved, two years later, the light learned about the appearance of "NFC labels", and after a year such a label Introduced into the phone Nokia 6131. In 2009, the same NFC forum created a standard called Peer-to-Peer, by which smartphones could exchange information with each other using NFC.

Now, many mobile gadgets have this technology, NFC labels can be found in a huge number of places: from metro stations and supermarkets, to museums and plastic cards.

Where and how does NFC technology apply?

Thanks to NFC has minimal dimensions and low power consumptionTechnology can be used in small equipment or devices. The chip in the phones can be installed on the battery compartment cover or if the removable battery is from the inside the back cover. In order for the user does not have difficulty in applying a device for transmitting information (which is characteristic of the use of large tablets), the location of the NFC chip is indicated by the tag applied to the housing.

One of the most common use of technology is Contactless types of payments. For example, to a mobile phone it is possible to bind a bank card, and in the future it is possible to pay with a gadget if the user has no cards with you. In the situation described, there is practically no probability of intercepting information, because the NFC interface has a minimal zone of action. Much more dangerous if the unlocked phone is lost or abducted.

You can use mobile payments - Apple Pay or Android Pay, whose action is based on NFC technology.

In order to carry out any payment through NFC, it is necessary:

Having a bank card with a marked paypass;
Mobile application of the required bank;
In this application menu, find the NFC item;
Machine to apply to the rear panel of the smartphone for reading;
Password sent to SMS, remember for the implementation of payment operations.

Other of the use options are information exchange. Despite the fact that the transmission rate is sufficiently small, the function can be used to send small text messages, contact cards, or links. Action algorithm when using the following function:

it is necessary to activate NFC. To do this, in front of the item in the category "Wireless Networks", you need to put a tick, further make unlocking the gadget and turn on the display;
you should choose the agent:

Google Chrome. If the transmission of the current links is needed.
Google Play. To transmit any content, which is provided in this service.
YouTube. If you need to give a link to a specific video.
Gallery. Used when transmitting images.
Contacts. Need to pass the contact card.

you need to bring the devices to each other before the signal is triggered;
touch the display and hold to confirm the need to transmit;
after the next signal, the transfer of files will be successfully completed.

Another use of the described technology is Record and read a variety of labels. This function works by analogy with the reading of the so-called, but in the case of NFC, a chip is used, not a gadget video camera. This can be useful in the case of automation of the processes of the house or at work.

In order to independently create labels, you will need to have clean blanks and intended for this application so that the information you want is recorded. The label can be associated with a variety of actions whose start will be made after reading the tag: sending email or SMS, telephone call to the number from the contacts, go to the link, launching mobile applications, and so on.

How to find out if the phone supports NFC technology

To do this, you will need to remove the rear panel (if it is a removable) smartphone and explore the battery. Most often on the front of the battery there is a certain mark confirming the presence of the NFC chip. Also, you can go to the phone settings, and in the "Wireless Networks" section, find the "NFC" string.

NFC Support Smartphones: Dear and Budget Options

Dear models:

SamsungGalaxy S8.. The model allows you to pay for the purchase contactless with the help of the payment service called Samsung Pay. Unlike many devices that can use NFC technology, Samsung Pay thanks to their own development - MST technology - allows payment to pay almost every terminal that receives plastic cards. The smartphone can support both Android Pay, but then MST will not be involved.
AppleiPhone 6.s. In order to use the possibility of contactless payments, this model uses its own service called Apple Pay. It will be enough to bring a finger to the scanner of prints, and the smartphone itself is to the payment terminal.
Xiaomi.MI5.s.. The flagship smartphone from the famous Chinese company also has a built-in NFC chip. You can use Android Pay in order to pay for the purchase. You need to add your personal map data to the mobile application, and in the future you can pay, bringing the phone to the terminal.

Budget models of smartphones equipped with a module

Surely some of my readers have heard of NFC technology. A number of people quite actively use this technology in their livelihoods, but the absolute majority of users are not familiar with it and rather vaguely understand what it is and how it works. This material is designed to shed light on this topic, I will tell you in detail that it is NFC in the phone, introducing the reader with the history of this technology, I will tell you what the principles of its functioning and how to use it.

NFC - Technology for Wireless Data Transmission

This term NFC is an abbreviation from the words "Near Field Communication" (translated "Communication of the Middle Field"). This name is not happened not by chance, since NFC is a wireless data technology to a short (up to 4 cm) distance using radio waves.

This technology is the expansion of the capabilities of the previously existing standard of contactless cards (ISO 14443 codification). The NFS works on the basis of the induction of the magnetic field and the relationship of the frame antennas, its operating frequency is 13, 56 MHz, and the rate of data exchange here is small, just 424 kbps.

Due to its small sizes, the speed of connection and low power consumption, this technology is massively used in small devices (in the so-called "NFC labels", smartphones, plastic cards, etc.). If you still do not know, I recommend reading the link.

What is it nfc and why it is a smartphone [video]:

History NFC.

In order to better understand that this is NFC in your phone, I recommend watching Viderolik above, and we are moving further and study the history of this technology. NFS is rooted in the technology of "radio frequency identification" (in English RFID), originated since 1983. Near Field Communication technology allowed via radio signals to record the necessary data stored in special RFID labels.

A year of the birth of the NFS itself, it is customary to be 2004, when three IT giants - Sony, Philips and Nokia created a "NFC" forum, a non-profit organization designed to promote the unified interface of the interaction of devices operating on the basis of a simple touch to each other.

Due to the further development of this technology, the so-called "NFS Tags" appeared in 2006, in 2007, for the first time, such a label was introduced in Nokia 6131, and in the 2009 NFC Forum, the PEER-TO-PEER standard was created, allowing smartphones using NFS to exchange each other with other contacts. , references, initialize Bluetooth and so on.

Now the NFS technology is included in the functionality of a set of mobile devices (support for this technology appeared in the Android OS version 4.0), we can meet NFS tags in the subway and supermarkets, on architectural monuments, bank cards, and so on.

Advantages and Disadvantages of NFC

What are the advantages of NFC in front of other alternative technologies (the same Bluetooth)? They are as follows:

Small radius of action. Due to the fact that NFS operates on a small radius of action, the likelihood of the interception of available data is very low. This is especially true in cash transactions, which reduces the possibility of their theft;
Quick connection between NFC devices. If, in the case of the same Bluetooth, some time must be installed on the connection setup, then the NFS connection occurs almost instantly;
Small device size. The NFS chip can be placed anywhere, and it creates a huge field of opportunities for its use;
Small cost. NFC labels can be purchased for a very small amount, while they are freely programmed with a smartphone.

The main disadvantage of this technology is the low data transfer rate. To compensate for this, some applications are trying to combine NFS technology with Bluetooth and Wi-Fi (when setting the connection between devices using the NFS velocity, and when the files themselves are transmitted - Bluetooth and Wi-Fi).

What is NFC label

Usually, the NFC label is called a small device equipped with an NFC chip. This label has no power supply device, feeding from the receiver (smartphone), without which it simply is useless.

Typically, such labels have the form of small transparent (or painted) circles that can be built into posters, monuments, advertising shields, stands in stores and so on. If your phone has a built-in NFS module, then you can read the information from this label (for example, considering the NFS Tag on the monument, you will receive information about the date of creating a monument, its creator, and so on).

How to find out if there is NFC on the phone

So, you decided to take advantage of NFC technology, and at the same time you are interested in how to find out if there is NFC on your smartphone, read further. Typically, manufacturers in the specifications of their device indicate the availability of NFS technology (you can search for information in the instructions for your phone). In addition, the mention of the presence of NFS can be seen on the battery of your smartphone (or under it).

Checking support for NFC technology in the phone

If the external attributes for the presence of NFS were not detected by you, then go to the settings of your android smartphone, select the "Wireless Network" item (or "Advanced Settings), and if your phone supports this technology, then you will see there an appropriate item (you need Put a tick for its activation).

What applies to the iPhone, the NFS technology was implemented from iPhone 6. On earlier models, this technology is absent.

How to use NFC on smartphone

To use the NFC function, go to "Settings" of your device and activate the NFC mode (usually it is in "Wireless Networks", but may be variations in finding this item associated with the specific version of your operating system). It is also necessary to use the "Android Beam" option, and take care that not one of the two devices (if both smartphones) did not have a locked screen or not in sleep mode. I hope you understand what kind of technology NFC and now we will learn to use it.

If one of the devices are the usual NFS label, it will be enough to bring the smartphone to it with the back side (with previously activated NFC and Android Beam functions) and wait for a characteristic sound signal, after which the contents of the tag will be read and appears on the PC screen (if the content is intended for normal visual demonstration). Such a technology is similar to the well-known QR-codes technology, which works in a similar way.

Thus, it is possible to share not only photos, but also by references, virtual business cards, text and APK files and other information relatively small size. To transfer large sizes, it is better to use other paths (Bluetooth, Wi-Fi, etc.).

In addition, there are a number of external applications using wireless remote technology in their work. For example, in File Expert HD, Send applications! File Transfer NFC technology is intended to quickly establish a connection, and Bluetooth or Wi-Fi is used to transmit data, which guarantees faster transmission of volumefile files.

To record the same information on the NFC labels, you should use the functionality of such NFC Retag applications, ABA NFC, SmartTag Maker and others.

Video review Near Field Communication

After we figured out that it is NFC on the phone, we can conclude that this technology has become an integral part of our life. Many of us can see its application when working with terminals and bank transactions, when transmitting information between smartphones, in public transport and many other places and spheres of public life. At the same time, the NFS functionality continues to expand and improve, and, sure we will meet more than once with the NFC-based technologies in the future. Here will see.

In contact with

Initially, Near Field Communication technology ( NFC.) I received the maximum distribution as technology to make contactless payments. You can use a smart card with a built-in NFC chip as a ticket in public transport, as a payment card in retail facilities, like a "smart" business card or as a contactless key card.

However, recently, this technology is increasingly and more often used in devices such as smartphones and tablets: almost all major manufacturers have begun to equip their models of medium and high levels of NFC adapters.

What is NFC?

If you translate the name of the Near Field Communication technology from English, we will get the phrase "Communication of the Middle Field", which can be deciphered to a normal language as wireless communication at short distances. Thus, we see that two NFC-compatible devices can communicate with each other when they are nearby. And indeed, the "long-range" NFC is just a few centimeters.

In mobile devices NFC, the technology can be used for various purposes. You can, for example, turn your phone into a virtual bank card, use it as a pass to the pool or an enterprise. You can also quickly share files and references, and even, using special applications, read and write information to programmable NFC tags or NFC smart cards.

In the Android operating system, NFC support appeared in the Android 4.0 version of Ice Cream Sandwich - its built-in Beam function allows you to exchange files between devices.

Why do NFC need if there is a Bluetooth?

As you remember, NFC is most often used when paying for various goods or services, and in this case, Bluetooth is not quite suitable. First, due to its large radius of action (there is a possibility of intercepting your payment data). And secondly, the connection between the two NFC devices, unlike Bluetooth, is almost instantaneous.

Is there NFC support on your device?

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

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

However, the easiest way is to check the presence of an adapter NFC in the phone or tablet, it is possible 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:

Activation NFC.

If your tablet or phone has a NFC adapter, you need to enable its use to exchange data between other NFC devices.

Go to Settings -\u003e Wireless Networks -\u003e More ...

Mark the "checkmark" item "Allow data exchange when combining a tablet with another device"

This will automatically turn on the Android Beam function.

If Android Beam does not turn on automatically, simply click on it and select "Yes" to turn it on.

When Android Beam is disabled, it limits the capabilities of the NFC data exchange between smartphones or tablets.

Data exchange using NFC

After you activated NFC, you can use it for data transmission. For successful data exchange, notes between tablets and phones, please note the following:

On both - and transmitting, and the receiving devices must be enabled NFC and the Android Beam function.

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

When you bring two devices close enough to each other, a beep sounds that the devices discovered each other.

Do not divide the devices until the data transmission is over, and you will not hear a signal about the successful end of the process.

Data transmission via NFC

Place the rear panels of devices against each other.

Wait until confirmation of the fact that both devices have found each other and will not appear on the sender screen. "Click to transfer data":

Click on the screen and data transmission will begin:

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

Exchange applications

With NFC, you cannot exchange APK files. Instead, the sender device transmits to another device link to this application on Google Play Market, and the recipient opens the page in the market with a proposal for its installation.

Web piping

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

Youtube video exchange

Again, when the YouTube video is exchanged, the transfer of the file itself is not performed - just the second device will open the same video on YouTube.

Using NFC tags.

In addition to sharing information between tablets and telephones, you can use your device for reading (and writing) data from NFC labels and smart cards equipped with NFC chip.

NFC chips are small enough, and they can be embedded anywhere - in business cards, bracelets, labels of goods, stickers, price tags and other items. They may contain data about a person, a URL address, product information and even the commands that your phone or tablet will have to touch these labels.

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

For example, using the Yandex program program you can find out how many travels remained on a one-time card of the Moscow Metro, and the NFC App Launcher program will provide you program your phone or tablet to perform certain actions by placing the appropriate information in the NFC label.

Conclusion

Most of the modern Android phones and tablets are already equipped with NFC adapters, but so far this feature is more in demand and its application is still limited, mainly the ability to quickly exchange content and contactless payment services. Nevertheless, in the future, NFC can penetrate all areas of our life, sometimes even completely unexpected.

Those of users who are not yet familiar with NFC technology are asked: "What is NFC and why this module is needed?" The abbreviation is decrypted as Near Field Communication (near contactless communication). Using NFC, devices can exchange data, but they must be at a distance not exceeding 10 cm.

The technology appeared in 2004, but she received a mass distribution recently. Mostly is used for contactless payment with a smartphone that saves time and is a very convenient function. Removing funds at the shop in stores also occurs through such an accessory as an NFC ring and smart clock.

He can also serve as a means of passing the institution and to identify the person. In addition, the module allows the Bluetooth function, but with the difference that has a much smaller radius of action and the possibility of an instant connection. That is, using it you can exchange content and different files.

So, how do the availability of NFC in the smartphone determine? Everything is very simple: you only need to go to the standard phone settings. Now there are several ways to learn whether your device supports this technology.

It should be noted that the module is present in most smartphones from market leaders. For some manufacturers, the presence of this feature can be checked by considering the sticker or the emblem on the battery.

NFC in Android settings

You can check the presence of this chip on the smartphone while looking at the android device settings. In the "Settings" menu, go to the "Wireless Networks" section and pay attention to the "still" key. If the NFC function is provided in this machine by the manufacturer, then the item must be for its configuration.

For the Android 8.0 Oreo operating system, for example, the instruction will look somewhat different. You must also go to "Settings" to the "Connected Devices" section. If there is a module in the list, activate it.

Quick settings and applications

There are also other ways to check the presence of the module, since in rare cases it may not be reflected in the settings. Swipe from the top of the display, call the rapid settings. They must present the corresponding label.

If, when using the second method, you did not find information about the module, then with a large probability, you can argue that contactless payments are not available on this device. There are also special applications that check the presence of NFC.

NFC in official characteristics

First of all, it is necessary to clarify in advance whether the module in the device you purchase. Examine the official characteristics of the smartphone if the presence of this function is important to you. Information about this is also in the instructions that are provided with the box.

What if there is no module in the device?

Even with its absence, the device has the ability to install an external device for communication in the form of a SIM card, chip, stickers and other things. Stickers are attached to the outside of the phone or inserted into the device. They are supported by most smartphones.

Today, technologies allow people to pay not only in cash and a bank card, but also a smartphone.

Behind contactless payments and mobile payment systems The future, they become popular with every day. Google for its operating system created Android Pay (now), Samsung and Apple - the same systems with the PAY console. They work according to the same principle - it is enough to bring the included unlocked smartphone to a non-contact terminal.

Today we will tell you how to use NFC, how to set up this feature, and what is needed for this.

Smartphone with NFC.

The first and most important thing - the device must be equipped. It is he who is responsible for non-contact operations. If there is no NFC in the gadget, unfortunately. The operating system version must be Android 4.4 and higher.

How to find out if there is NFC:

Our.
Official sites of manufacturers with a list of technical specifications.
Settings - more / optional / additional functions (depending on the version of Android and the branded shell). In this section, there must be NFC and Android Beam functions that need to be activated.

Supported Map

This is the second condition. If the card does not support contactless payments or a bank for some reason gives an error when setting up a card, bind it to the smartphone and Android Pay will not work, an error will appear. In this case, you can either contact the bank with a request to releasing the map, or order a new one.

Almost all modern cards, including Sberbank (except Maestro), Alpha, Tinky and others, support contactless payments. If you see such designations, it means everything is fine in most cases.

Depending on the smartphone brand, download the application. As it is clear, for all devices other than Samsung and Apple, you need a program (now called Google Pay). It is on its example that we will show how non-contact payment through NFC works.

After installing the application, it is necessary to start a credit card: it can be scanned through the gadget chamber or enter the number manually. Also, you need to fill out the validity period, the name of the owner and the CSV code (three digits on the back side). Then the data entered must be confirmed - to the phone number to which the map is attached, the SMS message will come with the code.

When this operation is executed, a bank card will appear in the Android Pay interface. At this stage, the application will definitely need to configure the screen lock - such Google Policies. You need to set a PIN code, a graphical key or password. In the future, it will be possible in the presence of a fingerprint scanner, the main thing is that the device is unlocked.
