NFC (Near Field Communication) is a fairly common function on most modern smartphones of the middle and high class. As the ecosystem of online payments spread around the world, its growth in popularity is observed. However, many still have several questions about this. What is NFC module? How to use it?

What it is?

Near Field Communication. a wireless standard designed for high.speed data transfer between two devices at a lower distance. One is a transmitter, and the other is a receiver. Both of them can be active or passive.

Passive devices do not require a power source for receiving and transmitting data, due to low energy consumption of technology. It can be terminals, readers or tags. They are convenient and can be placed anywhere. However, passive do not process the data on their own and are not connected to other passive devices.

Active support NFC and use a power source to work. They can send and receive data, as well as exchange it with other devices. The best example of the active device is smartphone.

Compared to Bluetooth, the technology has a much smaller radius of action. only 10 cm. But there is one area where the NFC action is invaluable. contactless payment through a mobile phone.

How NFC works

The abbreviation NFC hides three 3 words. Near Field Communication, which translates as “communication of the near field”. The main purpose of the function is to transmit information between devices at a distance of up to 10 cm. The process is carried out due to the induction of the magnetic field.

With active mode, both mating devices should have their own power supply. With passive mode, one power source is enough, in which case one of the devices is divided by the induction of EM-oblast with the other.

The NFC module has compact dimensions, so it can easily be installed in mobile phones, speakers, PC, etc.P.

Using NFC

Unlike the widespread Bluetooth technology, NFC is distinguished by the highest synchronization rate between gadgets. However, the transfer of files in active mode is very low. For this reason, NFC is mainly used to transmit “light” files, such as contact details, links or notes.

If the files are “heavy”, then the NFC is used to connect devices, and Bluetooth or Wi-Fi is already used to transmit information.

Most often, the NFC chip is installed on the back of the case, so to connect devices they are applied to each other with back surfaces.

How to check the presence of NFC

NFC is available on almost every high.class phone, but not on all outdoor and entry.level phones. One way to check if the NFC is in your phone is to find the NFC label, usually located somewhere on the back of the device. On some Samsung phones you will see the inscription “Near Field Communication” printed on the battery block. However, this applies only to old phones, since most new models do not have a removable rear panel.

On some devices, especially on Sony Xperia phones, you will see a N-tag behind, an official symbol indicating that the device supports NFC. N-Mark also shows the exact location of the NFC chip.

Or you can check the settings menu of your phone.

Depending on your device, this option may be located in another section. If you cannot find it, open the settings menu, touch the search icon on top and enter NFC. If it is on your phone, the NFC option will appear.

Activation NFC

If you performed steps from paragraph 2, then just activate the NFC switch. You can read more detailed instructions on how to enable NFC on the Android device.

What to do if the phone does not support the function

There are several budget options for replacing the built.in NFS module:

• Tags. a small sticker with passive magnetic induction, which is made in various design versions. Has a small cost and is easily attached to any subject. wallet, key fob, documents. But there is a significant drawback. for each individual function there should be its own label.
• SIM card. A simple and convenient way to set up contactless payments, but the user will have to contact the bank to bind the SIM card to a bank account.
• The external antenna NFS. Suitable only for smartphones with a removable back cover, since it is installed instead of a SIM card. It also has a higher level of energy consumption, therefore it is not recommended for phones with a small battery capacity. However, the antenna has an active NFS function and due to this provides a full cycle of data exchange.

In active mode, both participants in the interaction must have their own power source, which means their own magnetic field. In passive mode, one such device is enough, the second will work due to the magnetic field of the first.

First of all, you need to make sure that in smartphone Installed NFC module. Usually this information is on the smartphone itself. manufacturers make a mark on the back of the device.

If there are several entered cards, you need to choose the right card before payment, if it is not installed by default.

The next step is the installation of a password, a graphic key or fingerprint to unlock the screen if before your device had unprotected access to the device. This is a prerequisite for PAY applications necessary to protect bank card data.

It is not enough just to turn on the NFC to pay for purchases with a card or take cash. You need to install an additional application. Each large smartphone manufacturer has released its. On Android it’s Google Pay. Download it in Play Market and install it.

Next, we set up an application for contactless payment. If cards are already tied to your Google account, then select the right. If not attached, then add a new map. You can do this by photographing it with a smartphone camera. Or enter the number, CVC, the validity of the owner manually.

It will be necessary to enter additional data. mobile phone number, etc.D. Next, we agree with the conditions of use and wait for the confirmation code to the smartphone. On the phone in the “Safety settings” should be tuned to block the screen on the pin or graphic key.

Great, well done! Now the data of your bank card are recorded in the NFC chip of your smartphone! In fact, you created a virtual bank card, the data of which will be transferred to the reader in places of contactless calculations. It is advisable to reliably protect the smartphone (in case of theft) with good antivirus for mobile. And separately, I advise you to include the function of contactless payment only before purchases!

To pay payment, you must first unlock the phone, then bring the card to the reader. at the cash desk of the store (or ATM) and confirm your identity again. On my smartphone, for example, three methods of unlocking. code, fingerprint and face recognition. Google Pay will offer you more options for a comfortable unlocking smartphone.

How to configure NFC for payment by a Sberbank card?

To pay via Sper Pay, you first need to go to Sberbank online on a smartphone. Not always convenient, but safer. an additional barrier for thieves!

In principle, you can use the above settings from Google. But, in the Sberbank online application, its own separate Sber Pay tool for contactless payment has appeared. (Probably just in case). He is in the “settings” lrowth:

The principle is the same. Only tuning is faster. Just select the desired card and connect it.

As an additional security measure, you can now use Sber Pay instead of Google Pay.

Because in the case of theft of a smartphone by number 900, you can call the Sberbank customer service and they will quickly block your Sber Pay. By the way, I managed to use it normally or only Google Pay (just need to configure it to the end) deleting all the cards from Sber Pay.

Either completely deleting Google Pay from a smartphone and use Sber Pay instead. Together, these applications on my smartphone did not work. And separately. the flight is normal.
