Nfs chip what. How to find out if your phone has NFC? Features of the transmission of certain types of data

Home / Freezes

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. Main feature This technology has a short range of action (up to 10 cm), allowing contactless data exchange between devices located on 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 exchange photos, music and videos between phones Sony 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 understood, as a “carrier” of the NFC chip mobile phone(smartphone) was not chosen by chance, 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, with the help of this technology, the booking and sale of electronic tickets, payment for travel on public transport and car parking are carried out; NFC technology is also actively used in the field 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 1cm, which avoids false alarm functions.

NFC or Near Field Communication is a wide-ranging communication standard that is widely used in modern smartphones and tablets. If you have an Android device, you can use it to connect your smartphone to a wireless speaker or to make contactless payments.

No matter what you want to do with NFC, here's how to check if you have it on your device and how to turn it on or off:

This guide applies to Android 8 Oreo, Android 7 Nougat and Android 6 Marshmallow. The procedure is the same in Android 7 and Android 6. In this article, we use three sets of screenshots and instructions: one that refers to the pure version of Android 7 Nougat (left), another that refers to the modified version of Android 7 (right) and another for Android 8 Oreo with separate screenshots. For the screenshots on the left we used Motorola smartphone Nexus 6, and on the right we used Huawei P10 lite. For the screenshots that apply to Android 8 Oreo, we used a Nexus 6P smartphone.

Method 1: Search for NFC in the Settings app

This method is the fastest and works on all smartphones and tablets. First, open the Settings app. Then in the search box at the top, type and search for the word " nfc" If you see in a search result, for example, NFC or Near Field Communication This means it is available on your smartphone or tablet.

If you're using Android 8 Oreo, search works the same. If it doesn't show any results, you don't have NFC on your device.

If you want to activate it skip the next section of this guide and follow the general instructions in the third.

Method 2: Manually find NFC in your smartphone's settings

The longer process involves first opening the application " Settings" On Android 7 or older, find the " Additionally". Usually it is in the category " Wireless networks"or somewhere below Bluetooth. Click " Additionally» .

If you are using Android 8 Oreo, find your connected devices and click on this entry.

You will then be shown a list with additional settings. One of them is the name NFC or Near Field Communication. On some devices it has a switch to turn the feature on or off, and on others it is a category of settings that you need to open. If the latter applies to your device, tap NFC or Near Field Communication to access the available settings.

The same can be said in Android 8. You see more settings and one of them is NFC, accompanied by a switch.

If you want to activate it on your device, set the NFC switch to " On .».

The same is true in Android 8 Oreo.

If you want to deactivate it, follow the same procedure to find NFC related options and set the same switch to " Off .».

NFC on a phone is a wireless communication technology high quality with a small radius of influence, which allows you to exchange information between two gadgets without contact. NFC is based on RFID, which is radio frequency recognition, which is a method of mechanically identifying an item.

What is NFC?

NFC is a contactless technology that can read and send information from devices over not very long distances. The abbreviation stands for "Near Field Communication". It is based on the principle of exchanging radio signals, identical to Bluetooth, but there is a significant difference. Bluetooth transmits data over long distances, several hundred meters, and NFC requires no more than 10 centimeters. This technology was developed as an extension for contactless cards, but it quickly gained popularity, and developers found application for it in other devices.

There are three ways to use this technology in cellular phones:

read mode;
emulation, when the device works like a payment card or pass;
P2P mode, when information is exchanged between phones.

The chip is stored in the cell phone and is used as a means of payment; you can book tickets, pay for car parking or metro travel, and provide access control. Thanks to technological payment processes without contact, MasterCard PayPass and Visa PayWave cards with integrated antennas appeared, where the role of NFC was taken into account, and applications for Android smartphones were developed.

What is NFC in a smartphone - with close contact, a pair of devices communicate through magnetic field induction, when closely contacting loop antennas form a device. NFC covers frequencies in the 13.56 Megahertz spectrum, and the information transfer speed can reach 400 kilobits per second. The device operates in two modes:

Active. Both gadgets are provided with a power source and transmit information in turn.
Passive. The field power of one of the devices is used.

Which phones have NFC?

NFC on your phone gives you the chance to pay for purchases by touching your mobile phone to the terminal; it’s a kind of bank card on your cell phone. Just 6 years ago there were few devices that supported NFC, but now tablets, watches and other devices are equipped with chips. Which phones have this device:

Apple – all iPhone models;
Sony – Xperia S, L, Z series;
Samsung – Galaxy S series;
Motorola;
Nokia-Lumia.

How can I tell if my phone supports NFC?

How to check if NFC is available on your phone? There are several ways:

Remove the back cover of the smartphone and inspect the battery; it should have the inscription “NFC” on it.
In the settings, find the “Wireless Networks” tab, click on “More”, if the technology is available, a line with the name of the technology will appear.
Swipe your hand over the screen and open the notification shade, where this option will be listed.

If there is no NFC, what should I do?

NFC on the phone - what are these modules? The following main types are distinguished:

SIM cards;
external devices;
microcircuits;
NFC modules;
stickers.

The NFC module can be purchased together with the phones, but they are also sold separately. Stickers are attached to the cell phone body; they come in two types:

Active. They provide communication via Wi-Fi/Bluetooth, but consume a lot of energy, so they require frequent recharging.
Passive. They do not exchange information with the phone and do not record it into the device through mobile communication channels.

How to install an NFC chip in your phone?

If it is not initially included in the device, an NFC module for the phone can be purchased and installed. There are two options to choose from:

NFC SIM card, many mobile operators now sell them.
NFC antenna. If there is no near field, this is the best solution. Communication shops also have such devices; they are glued to the SIM card, under the cover of the mobile phone. But there is one drawback: if the back cover is not removable or the SIM card hole is on the side, you will not be able to install such an antenna

How to enable NFC?

A device with NFC can be used not only as a wallet, travel card, or discount coupon; special tags also help to read data about goods in stores, and about any objects in museums and galleries. How does it turn on?

In the settings, select “Wireless networks”, then “More”.
The required inscription will appear, check the “Activate” box.

If your smartphone has an NFC chip, you need to activate Android Beam:

In the settings, click the “Advanced” tab.

Click on the NFC switch, the Android function is activated automatically. If this does not happen, you need to click on the “Android Beam” tab and select “enable”.

In order for data exchange to go smoothly, you need to make sure that both phones support NFC and Android Beam, first you need to activate them. The following is the action plan:
Select a file to transfer.
Press close to each other back covers phones.
Keep devices until sound signal, which will confirm that the exchange has ended.

Regardless of the type of file, NFC technology assumes the following information transfer algorithm:

Keep devices only reverse side one to another.
Wait until they find each other.
Confirm the request for data transfer.
Wait for a message that the process has completed.

IN lately You can increasingly hear mention of a certain NFC technology in the context of electronic payments via smartphone. Many people use it without knowing either the name or the principle of operation. There are a lot of rumors around NFC that touch on the security of personal data, money, and sometimes health. It is to explain such questions that this article was written.

NFC on a phone - what is it, how does it work and where is it used?

The NFC abbreviation is literally translated into Russian as “near-field communication”. From the name you can immediately conclude one of the main features of NFC - data is transferred at a very close distance, up to 10 cm. Of course, nothing prevents you from exchanging information at a distance of several centimeters via Bluetooth or Wi-Fi, but it’s worth understanding the details here .

The operating principle of NFC is based on the phenomenon of magnetic field induction, through which short-range high-frequency data transmission is realized between two devices at a frequency of 13.56 MHz.

One of the reasons for the existence of this technology is the need for security. It is logical that it is physically difficult to “hack” a contact that occurs in a small area, unlike the rest wireless connections. But why is such technology needed if it cannot be used to communicate with a device located even ten meters away? It's simple: NFC has a completely different focus. From the obvious - contactless payment by holding a smartphone to the terminal. But this is far from the only area in which NFS can be used.

Examples of using the NFC chip:

Transfer media files, contacts or settings between smartphones.
Cashless payment. Perhaps the most popular option for using the system, which is widely used in Russia. There are also various options: payment for travel, provision of personal data by touch, etc.
Reading information. NFC tags in smart cards and other objects allow you to instantly enter information into your smartphone, for example, from a business card. NFC chips are small enough to be built into almost any item.
Some Sony TVs have a function One Touch Mirroring, which allows you to display video from your phone's memory on the TV screen.
Access control to various services or objects where a device with an NFC chip is used instead of a key.

The first phone equipped with NFC appeared back in 2006 (Nokia 6131), but such devices became widespread only in recent years, and now NFC can be found not only in flagships, but also in mid-price segment models, and even budget smartphones.

Benefits of NFC

Instant connection setup. NFC allows devices to connect without additional manipulations, entering settings, etc., just bring two gadgets with NFC chips close to each other.
Safety. As already mentioned, the short range makes the hacking process much more difficult, but this does not mean that NFC does not have other means of protection. In addition, if you lose a bank card, the risk of losing the money on it is much higher than if you lose your phone, where the funds are protected not only by a password, but also by the need to confirm access to the gadget itself.
Ease of use. You can add several bank cards to your smartphone’s memory and pay with them from one device; in addition, NFC works not only with bank cards, but also with transport and discount cards.

Which devices support NFC

Most modern smartphones support this technology, but older or low-cost solutions may not have it. Some manufacturers put the name of the technology on the surface of the device body, but there are more effective way check if it is on your smartphone:

Open the device settings menu.
Go to "Wireless Networks" or "Connected Devices".
Open "More".
Find NFC.

And of course, you can always just google the name of your smartphone adding NFC next to it, and everything will become clear.

How to pay by phone

Here we will consider the most popular way to use NFC - card emulation. Using emulation, you can create a virtual duplicate of the card and pay from your phone, as if using MasterCard PayPass or Visa Paywave cards, which are simply applied to the terminal to write off funds.

Smartphones with an NFC chip running on Android OS are produced contactless payment using the application Android Pay, which can be downloaded from the Play Market using the following link. Phones from Samsung work with a proprietary application Samsung Pay, which is usually preset in operating system out of the box. The operating principle of both applications is completely identical.

A user who has never used a password, gesture, or fingerprint to unlock a device will be forced to set up secure access to the device when launching Android Pay for the first time. This prerequisite to use contactless payment.

How to use Android Pay:

If you have connected more than one card, you must first select the one that will be used for payment, if it is not installed by default. Transactions are confirmed the moment the smartphone is unlocked using a code, graphic key or a fingerprint scanner. Payments in the amount of more than a thousand rubles, at the request of the seller, may need to be confirmed by entering a PIN code from bank card in the terminal or by signature.

For quick access to NFC, pin the activation icon for this function in the notification shade so as not to look for it in the jungle of settings every time you need to pay.

How to pay with a smartphone on the subway or bus? This is done in a similar way: launch Android Pay, confirm authorization and pay for the trip by touching the smartphone to the turnstile. In the same way, you can pay for admission to museums, exhibitions and similar places, without having to stand in line for a ticket.

Share data and files via NFC

To transfer files from smartphone to smartphone via NFC, the Android Beam assistive technology (or Samsung Beam on devices from the same manufacturer) is used. Let's figure out how to send files via NFC:

In a similar way, you can transfer other information, for example a list of contacts, which makes life much easier when moving from an old smartphone to a new one.

Conclusion

Since most smartphones have long been equipped with an NFC module, today the basis is being formed for changing the electronic payment system. And despite the fairly high popularity of NFC as a payment method, the demand for this technology (relative to its potential) is very low. In the future, NFC may become an integral part of our lives, just as smartphones themselves once became, since paying with your phone is really convenient.
