How to connect NFC on Samsung

Samsung was one of the first companies to introduce the use of contactless communication in its smartphones.

Generation 4 phones.4. “KitKat” are equipped with this option. Radiofrequency signal is generated by the loop antennas of two devices and allows instant connection. Samsung labels the phone models that support the option. Near Field Communication is marked on the battery case and in the phone menu, which means that the phone can work in Near Field Communication mode.

Basic NFC functionality in Samsung:

• Making payments through contactless terminals;
• bank account transactions (via special payment applications)
• data transfer to special tags;
• Paying for travel on transport;
• synchronization with other devices;
• Programming the phone to work in a given mode (volume, melody, brightness).

Technical parameters of the option

Wireless short range transmission in Samsung has certain operating parameters, which are summarized in the table below.

Advantages and disadvantages of contactless function

• High speed of connection setting (you just need to put the phone close to the terminal and the option will be automatically activated).
• Ease of operation (the user may only be required to perform additional authentication. graphic password, fingerprint, retinal scan).
• Safety (the terminal does not receive information about a person’s payment data, but only tokenized data from the server or remote database).
• Extended compatibility with other contactless systems (compatible with several payment applications).
• Wide functional potential (work with several banks, electronic wallets, travel systems).
• Does not transfer some types of data (web pages, apps).
• Works only on short distances.
• Built in only in modern models of smartphones.

Enabling NFC on your Samsung phone

It is possible to switch on the option through the settings menu of the phone.

To do this, you need to enter the main menu and follow the further algorithm:

• Call the settings menu.
• Find and press icon “Settings” (gear wheel).
• Go to “Wireless Networks” and expand the “” submenu.
• Scroll down the list to the NFC and Android Beam lines.
• In the line NFC allow the information transfer by ticking a special box.
• At the “Android Beam” line, check that the feature will connect automatically.

Do I have to do something if the automatic activation did not happen?

Since the Android Beam option, when disabled, limits the possibility of establishing a connection with other devices, in order to save time during the data transfer it is necessary.

The feature is still under development, the potential for its use expands every year. Understanding what NFS in a Samsung phone will allow you to effectively organize personal and work operations. For those who need to check the presence of such technology, above is a guide to where to find the marking and how to enable the option.

The abbreviation NFC (. Near Field Communication) literally stands for Near Field Communication. Each NFC module contains an electromagnetic sensor, through which the data is sent to another device.

NFC technology was not so long ago, but has managed to win popularity all over the world. NFC allows you to send media files between devices and to make contactless payments. The latter is especially relevant for owners of gadgets with a built-in module.

Many modern devices have a built-in NFC chip:

The owner of a camera with NFC doesn’t have to worry about running out of memory on the flash drive. NFC activation is enough to free up some space on the device and transfer the data to the smartphone. Files from the phone can also be placed in cloud storage.

Many public places have terminals with built-in NFC technology. They have a special icon on the screen which means it accepts contactless payments.

To make a payment with a smartphone, the user only has to attach it to the terminal with the PayPass option. The funds will be written off instantly, and the screen will display a notification of a successfully conducted payment.

Unfortunately not all smartphones today are equipped with an NFC chip. Specially for owners of such gadgets were invented external modules. They are offered in three kinds:

An external module can only be connected to a smartphone with a removable back cover and an internal SIM card slot.

This module can be found in a cell phone salon or online store. For further payments, it is important to attach the bank account to a valid SIM card, so that the payment can be made instantly.

What does the NFC icon mean on Samsung?

Owners of new smartphones often wonder what NFC is in a Samsung phone? The presence of a built-in chip is indicated by a special icon on the back of the smartphone. The owner of such a gadget can attach the main means of payment to the application and pay for purchases with just one touch.

All Samsung smartphones have the Android operating system. To check if there is NFC on a particular model, you need to open the phone settings and go to or Wireless Connections. The option will pop up on the screen and must be switched on.

On some devices there is an additional option Android Beam. It is also necessary to activate it for fast data transfer between gadgets.

How to pay with NFC?

Owners of Samsung smartphone can use a special application Samsung Pay for contactless payment. The user ties his or her bank card to the app and can then pay with his or her smartphone anywhere.

Samsung Pay is available for almost all Galaxy and Note series models. The official Samsung website has a list of all smartphones with built-in NFC and app support.

After a successful download, a bank card must be linked to Samsung Pay, which is typically used for payments.

The app also supports e-tickets, discount cards and gift certificates. To avoid carrying around a wallet anymore, you can connect all the necessary cards to your Samsung smartphone and use them as needed.

Do I need to enable additional options??

For contactless payments, the user only needs two settings:

Then he can simply unlock the screen, bring the phone to the terminal and make a purchase. No fee will be charged.

Many Samsung smartphones have a built-in NFC module. This feature lets you pay with your phone anywhere there’s a terminal with built-in PayPass technology. Users no longer need to carry a wallet payment means are now always at their fingertips.

How to set up NFC on your phone

NFC is a technology of short-range high-frequency wireless communication, which is used to transfer data between devices. Unlike Bluetooth and Wi-Fi already known to users, NFC works only when the devices are placed very close to each other. precisely, the maximum distance between the interacting devices is 10 cm.

Capabilities of

NFS technology is known to users because of the possibility to pay for services and goods with the help of a cell phone. The module supports Google Pay and Apple Wallet services and provides an additional degree of protection against intruders. The user can emulate a one-time code for each transaction lasting several seconds and completely exclude unauthorized payments from his card.

Additionally NFC technology will help instantly make a payment in the subway or on ground transport, transfer graphic, video or text data between devices.

Which models have a built-in module

Phones with NFS first appeared on the market in 2004, but the budget models still do not support the technology. The built-in module is equipped with devices in the medium and high price segment.

NFS is supported by all iPhones starting from iPhone 6. But not everything is so clear with Android-based devices. One of the leading companies on the market. Samsung is actively developing its own payment system, so there is no NFC in many smartphones of this manufacturer, and popular among users brands Meizu and Xiaomi do not add the module in the most popular phones to reduce their costs.

The price starts at 7,500 for the ZTE Blade A7, and the maximum bar can be considered conditionally the Samsung Galaxy Fold for 128,000

The list of the most popular models in 2020 includes:

• CAT S61 (75,000 )
• HUAWEI Nova 5T (28,000 )
• Samsung Galaxy A51 (

To find out if your device supports NFS, you should:

• Swipe the screen, open the “Quick Settings” menu and look for the abbreviation NFS.
• Go to “Settings”, select “” and look for NFS.
• Download a free app from Google Play to detect the module, such as NFC Enabled.

In addition, some manufacturers place a special sticker on the battery or body of the device.

What to do if your phone does not support

There are several budget options to replace the built-in NFS module:

• Tags. small sticker with passive magnetic induction, which is made in different designs. It has a low cost and is easily attached to any object. wallet, keychain, documents. But there is a significant disadvantage. for each individual function there must be a different tag.
• SIM card. Easy and convenient way to set up contactless payments, but the user will have to go to the bank to tie the SIM card to the bank account.
• NFS external antenna. Suitable only for smartphones with removable back cover, because it is installed instead of the SIM card. Also has a higher level of power consumption, so it’s not recommended for phones with low battery capacity. However, the antenna has an active NFS function, and thus provides a full cycle of data exchange.

How to turn on and set the NFC on the phone: step by step guide on Android

In order to turn on the wireless connection:

In this case, the Android Beam function should automatically start, if this does not happen. you should enable it in the settings in manual mode.

The next step is to figure out how to set up NFC payment on Android:

• Download the Google Pay app from Play market.
• Tie the card that you are going to use for contactless payment. To do this, enter the name of the owner, the number and expiration date of the card, the CVV, which is on the back of the plastic.
• After confirmation, a verification message with a code will be sent to your phone.
• Confirm linking to the card.

An unlimited number of cards can be linked to one phone, including debit, credit, virtual and gift cards.

In order to pay by contactless payment method on Android, it is necessary to bring the phone from sleep mode, hold it to the payment terminal for 1-2 seconds and wait for the confirmation of the payment, which appears on the terminal screen.

The user does not need to enter the application specifically to make a payment, just unlock the device with NFS. It accelerates and simplifies the payment procedure.

Setting up NFS on iPhone

In order to use contactless payment service iPhone users need authorization in iCloud and connection of Touch ID. Then follow the instructions:

• Go to Wallet app.
• Select “Add Card” and then “Next.
• Enter card number and expiration date, owner’s name and surname, CVV code.
• Accept conditions of user’s agreement.
• Wait for the verification code, which will come via SMS.
• Enter the code to confirm the card binding.

No need to worry about the security of NFC payments. Firstly, in order to carry out such transactions the devices should be in close proximity to each other, and secondly, any transaction over 1000 will require password confirmation.

What to do if NFC payment does not work

The reasons are rather many. They appear as mushrooms after the rain. Especially recently, characterized by an increase in the number of model names that use this option.

Here are errors and problems from which a solution was found. Maybe this will help someone.

• Simple mistakes. Here you can find faults and mistakes of the user.
• Low charge of the battery, it is not possible to make a transaction with less than 5%.
• The balance on the linked card does not allow you to pay.
• NFC-chip is disabled in the settings.
• Terminal does not display the logo you are looking for and you are trying to enter a locked gate.
• Your bank card is is not supported.
• Software errors.
• Application does not want to install? There may be several reasons, from geopolitical to trivial. As an option, see if the memory is available in the device. Also, check with Google to see if your country is a follower of it?
• If payment does not pass for unknown reason, not classified, there is a way out. Try to do the so called software reset. Delete the linked card from your account and register it there again. Sometimes it helps.
• Does not connect to the payment system. Restart the application, it is possible glitches of the utility itself.
• Technical. Known bug 56 in the Apple Pay app. Indicates an NFC module malfunction. Besides, there are cases when a wrongly oriented device with a chip refuses to be friendly with the merchant equipment. Try changing the position of the phone.

Here I finish, because this article is not a “rubber one” and it cannot fit everything in here. Look for a simple solution, you will think of a complicated one only in case of failure.

Despite the fact that many aspects of the question of how to set up for payment with a card duplicated by a phone and use NFC technology are covered in quite some detail, indecision remains. Proceeding from a general distrust to a new method of payment, expressed on many Internet sites, I want to summarize. Time will tell, as we like to say on TV.

NFC (NFC for. Near Field Communication) is the technology of data transfer between devices at close distances. The function relies on a built-in special chip in both devices to receive the data signal. For example, the user can send multimedia files from a smartphone to a smart watch, or from a camera to a smartphone.

NFC technology also combines apps and payment methods saved on each device. To make a purchase with smartphone is enough to do the basic steps:

How to use NFC on Android

• Set up a payment in a special app;
• Connect an external module or activate NFC inside the phone;
• Bring a smartphone to the terminal and wait for the payment to be completed.

Payment information can be saved on multiple devices at once. For this purpose it is necessary to download the application with the mark Pay on Google Play or App Store on all the gadgets with built-in NFC chip and add to it a bank or virtual card from which the funds will be deducted with each purchase.

This option is very convenient in a family circle, where all family members use one card to pay. Also, the user no longer has to worry about forgetting the wallet at home. The means of payment will always be at his fingertips.

Applications for contactless payment have certain system requirements. On Android, the most popular is Google Pay. It is suitable for phones from different manufacturers. To activate it, you need the following smartphone parameters:

• Built-in NFC module;
• Android OS version 4.4. and above;
• Official firmware;
• Locked bootloader;
• No active root-right;
• Phone certification from Google.

If NFC can be connected externally, then Android apps won’t work on custom firmware or an unlicensed smartphone. Fans of advanced settings will also have to abandon them in favor of contactless payments.

Is it possible to install the NFC module on the phone?

The latest models of smartphones are most often equipped with a built-in NFC module. But what to do for those who have older versions of phones?

You can buy an NFC module for your smartphone in several forms in online stores and cell phone salons:

External modules are suitable for smartphones, cameras and smart watches. They work on par with the standard built-in chip and can also transfer data between devices.

How to embed a chip into a device? It’s very simple: The SIM card or tag is inserted into a regular SIM and memory card slot. The NFC antenna is carefully attached to the active SIM-card and remains with it inside the case.

NFC antenna cannot be connected to the smartphones with a side hole for SIM-cards or with a fixed back cover.

The easiest way is to contact the operator of cellular communication and ask to replace the usual SIM card with a card with a built-in chip. However, there are a couple of nuances to consider:

• Replacing the SIM card may change the phone number;
• A bank account should be attached to the SIM;
• The choice of the bank is up to the operator.

After an NFC SIM-card is installed, the user can make payments with the smartphone. The amount of the purchase will be deducted from the bank account attached to the SIM. After each transaction the phone will receive an SMS-notification from the bank with the specified payment.

One more way of sticking a sticker with built-in NFC chip on the body of the device. Each sticker has a unique identification number and certification.

To use the module, you just need to open the back of your smartphone and attach the sticker to the device. Then it is necessary to install the NFC Tools application on the phone, which allows you to configure the external module and to make the payment.

How to enable NFC on Android?

Setting up NFC on Android with a ready-built chip is much easier. On all smartphones of the given operating system the setting is the same.

To activate NFC you need to open the standard settings of the phone and go to the section. It can be found directly in the main menu or in the Wireless Connections tab.

This section contains the contactless payment option. Next to it, it is necessary to put a tick for activation or move the checkbox to the right (depending on the model of smartphone).

You should also pay attention to the Android Beam feature. It, too, must be active in order to send data to another device.

On the Contactless payment tab select application, through which payment will be performed by default.

If the user does not have such settings in his smartphone, his model does not support NFC data transfer.

How to connect a payment tool?

After successful activation of NFC service you should download the contactless payment app. Google Pay is most often installed on Android, since you can attach multiple cards from different banks to it for payment. Some users like apps from specific banks, such as Yandex.Money. Samsung owners prefer Samsung Pay as it is optimized for their smartphone.

To learn how to pay with NFC on an Android phone, just follow a couple of steps:

Let’s consider the actions in detail on the example of Google Pay.

How to download Android Pay to your phone? Open Google Play and enter the app name into the search box. Select the desired option among the offered ones and press the Install button.

App will load in a couple of minutes. After that you should press the Open button.

The program will request access to the location and data from your Google account. Then you will be asked to add a bank card as the primary means of payment. The system accepts Visa, Mastercard or Maestro cards. The user needs to enter:

Next, you should enter your phone number to confirm the data. SMS with one-time password will be sent to your mobile phone, and you’ll need to enter it in the application.

Then you need to activate the custom lock screen. As the app contains sensitive data, it requires additional protection from intruders.

To activate the password, open your smartphone settings and go to the Lock screen. Here, the user can choose a picture key, fingerprint, pin code, or Face ID to unlock.

After blocking you should reopen Google Pay. The main page with the added card will appear on the screen.

If the owner of the smartphone for some reason does not have a plastic card, he can use the virtual card for contactless payments. It can be opened in any application of the bank online.

The emulation card has the same data as a normal plastic card. The only difference is that you can pay with it only through online applications.

Yandex.Dengi, for example, initially offers all new users to open a contactless card for free. This is done in minutes, and then you can immediately make purchases with it.

To find out how to add a virtual card, simply go to the Payment section and click on the Payment Method tab. The data of the card will need to be entered manually.

Google Pay also has a Cards section where you can add travel cards, loyalty cards, and gift certificates. This section is especially useful for those who pay with NFC phone in the subway.

Almost every resident of Moscow and Moscow region has a personal fare. The Troika card on Android NFC is easily attached through the Cards section of Google Pay. After that it can be automatically recharged through the app and used on any public transport with a smartphone.

How to unmount a card from the system?

To deactivate the card in Google Pay or any other app, just open the Pay section and select the desired card. In the right top corner there will be an icon which, when clicked, will give you the option to disable contactless payment. Through the option you can also delete the card from the system completely.

The app or NFC does not work what to do?

If NFC Android has malfunctioned, or the app has stopped responding to contactless payment, it is recommended to contact Support.

On the official site of Google Pay there is a section Help and support, where the standard questions of users are located:

• NFC and payment what the function is?
• How to install NFC module into your device?
• How to activate the card in the app?
• What does the error during payment mean??

In the field Describe the problem you should enter a suitable request and find the answer option. Or fill out the request form on the site with a detailed description of the problem.

NFC on Android allows you to exchange data between devices and make contactless payments. Many smartphones have a built-in NFC chip. An external module can be installed on the gadget, which will work on a par with the standard chip. To pay for purchases with a smartphone, all you need is an active NFC module and contactless payment application with a bank card tied to it.

How it works?

The technology behind NFC is similar to RFID, which uses radio waves to send and receive data. The difference is that Near Field Communication uses a new set of protocols for wireless communication, and limits it to only a specific 13.56 MHz frequency.

The sender and receiver must be in close contact with each other. about a few centimeters. to initiate the transmission. Once this has occurred, the data is encrypted. Electromagnetic fields are engaged to transmit actual data. The recipient may then need to send back the encrypted data, repeating the cycle until the transaction is complete. The entire process takes a few seconds.

One of the best features of NFC is support for passive devices that do not require a power source. Instead, they are activated by the electromagnetic field of an active device that comes into range. The generated power is sufficient to receive the data from the sender.

Near Field Communication supports three modes of operation depending on the situation:

• Peer-to-peer, which facilitates two-way data transfer between two devices. Smartphones use peer-to-peer mode during transactions.
• Read/write mode describing one-way communication pattern. In this mode, one acts as a transmitter and the other as a receiver.
• Card emulation, when the active device acts as a Smart card that can be connected to the terminal.

How to set up NFC for payment: step by step guide

First of all, it is worth making sure that the following conditions are met:

• Phone with NFC chip. You can find out about its availability on the manufacturer’s web-site, in the instructions for the phone, or by searching the “NFC” point in the “Wireless networks” section of the settings or by installing the “NFC Check” application.
• Suitable operating system: Android from version 4.4, iPhone version 6 or later.
• The possibility should be supported by the bank. It shouldn’t be a problem right now: all major financial institutions have enabled contactless payment via smartphone.
• Requires that there is no additional intervention in the phone: you need the original firmware, no root rights, Bootloader turned off. All of these options could only appear if you set them up and turn them on yourself, so you need to know how to turn them off. I will not dwell on this in detail.

If everything is OK with these items, you can set up the payment. To give you an example, here’s how to set up NFC to pay with a Sberbank card on an Android phone. The procedure for other banks will be similar, but I will outline the iPhone nuances below.

enable NFC on your smartphone

Before enabling NFC on your device, you need to check if you have the module as described above. Next, you should configure it: go to “Wireless Networks” or “Advanced Features” and click on the appropriate switch.

select a payment application

This option could be in the “Advanced Features” or NFC settings. Usually one of the three applications is used: Google Pay, Apple Pay and Samsung Pay. The latter is only available for top-of-the-line Samsung models. In our Android example, the app needs to be downloaded and installed on your device (we usually choose “Google Pay”). Remember that it is set by default).

Start adding your card

Now to set up NFC payment on Android you need to enter your payment data once. I’ll tell you about the full version of this step. However, if you have the bank app (in this case, Sberbank) installed, things are much simpler. I’ll tell you about it below.

In general, open the Google Pay app. You will see a “”. Tap on it.

Scan the card or enter the data manually

The app will ask you to scan (take a photo) the map. It’s very convenient because it takes a few seconds. If for some reason the procedure does not work, then click on the caption at the bottom of the screen and enter the data manually. At the very end you need to double-check the data and enter the CVV2/CVC2 code located on the back of the card.

/

Confirm

Google will show you the terms of using the service which you will have to accept by pressing the button at the bottom of the screen. After that the application will ask for confirmation from the bank. Usually it comes in the form of a code in an SMS. Afterwards, you will receive a code in SMS, which you will need to enter in the appropriate field.

check and set up the card by default

The bank will send a confirmation via SMS, and in some cases a small amount (up to 15 depending on the bank) will be deducted from the account, which will then return to your account.

After confirmation, setting up NFC on your phone for payment is complete. You will see a list of cards, one of which you can set by default. Now you can start paying!

payment

Internet connection is not required to make the payment, but NFC must be set up (enabled) on the smartphone beforehand.

Advise at the cash desk that you will pay by card. Unlock your phone and bring it to the payment terminal provided to you. For small amounts (up to 1,000-3,000, depending on the bank) you won’t have to perform any additional steps. You will see a green checkmark and know that the transaction was successful. No card, and the procedure takes seconds!

Note: adding a card through the bank app

This option is much faster and more convenient. You will install the official application, authorize in it, and click “Add to Google Pay” in the properties of the desired card. After confirmation you can go to the store and pay with your smartphone, you don’t need to set anything up additionally.

Enabling the NFC function

The first step the Android device user must take is to check if the contactless option is available on his or her phone, and then activate it. Verification and activation will be carried out according to the following algorithm:

• Turn on your device.
• Find the “Settings” menu (gear) or call from the notification panel.
• Go to “Wireless network” subsection and choose “”.
• Swipe through the actions and find the NFC line.
• Under the line activate checkbox “Allow information transmission”.
• Wait for activation.
• Find the Android Beam bar and tap it with your finger to turn it on.

Contactless communication function is connected, but its interface is not enough for financial transaction processing.

You should perform the next step. install the payment service.
