NFC Expert What devices and phones does the system work on
Samsung Pay is a mobile payment system of a Korean company. Its main feature is the ability to make payments through terminals equipped to interact with magnetic tape cards that are familiar to many. To do this, in modern Samsung smartphones that support working with the service, MST technology is implemented.
With its help, the phone generates an alternating current, thereby creating a field that can change dynamically. It operates approximately at a distance of 8 centimeters from the reader. At the same time, the terminal is sure that the payment is made with a conventional magnetic card, so there is no need to re-equip it.

The owner of a Samsung smartphone with service support adds credit card data to the application, which subsequently enters Samsung Knox and remains there in encrypted form. Before making a payment, he selects the desired card, gains access to it by providing his fingerprint or entering a PIN code, brings the device to the terminal and waits for the transaction to complete.
During payment, the smartphone does not send the card data to the device for payment, but a 16-digit code called a token, so attackers will not be able to intercept them during the “communication” of the mobile device and the terminal. If they manage to get hold of the token, then they are unlikely to be able to do anything with it, since the system will immediately block it when reused.
Example of making a payment using Samsung Pay
You can now pay with Samsung Pay on one of the following Samsung Galaxy models: S7, S7 Edge, A3(2017), A5(2016/2017), A7(2016/2017), Note 5, S6 Edge , S6 Edge and S6. Interestingly, on the last two devices, payment is made only using NFC technology. Versions of Samsung Galaxy A3 and A5 2015, as well as S5 and Note 4, the service is not available.
List of devices supporting Samsung Pay
Samsung provides full access to the payment system only to owners of its smartphones. Owners of mobile devices from other manufacturers cannot use it. At least for the reason that their firmware lacks Samsung Knox technology, which stores all credit card data in encrypted form.
The Samsung Pay app is not available for devices without updated firmware and smartphones from other manufacturers
How to connect Samsung Pay
On Samsung J6
Despite the rather conflicting information on the net, the Samsung Galaxy J6 smartphone does not have a contactless NFC chip, so it is not possible to connect Samsung Pay.
On samsung J8
The Samsung Galaxy J8 also does not have an NFC module, so neither Samsung Pay nor Google Pay are supported.
On Galaxy Watch
Only NFC payments are available on the Galaxy Watch. It is not known why Samsung abandoned the main competitive advantage – the use of MST technology – in this gadget. Therefore, Galaxy Watch can only be used in terminals with contactless payment. The Galaxy Wearable app is used to link the watch to a smartphone.
- Launch the Galaxy Wearable app on your mobile device.
- To complete card registration, select “open Samsung Pay” and follow the instructions on the screen.
- To make a payment using your Galaxy Watch, press and hold the back key.
- Scroll through the list of cards, select the one you want, then select “Purchase”.
- Bring your Galaxy Watch to the terminal. After the information is recognized by the terminal, the payment will be made.
On Gear S3
Samsung Gear s3 smart watch fully supports Samsung Pay functions. Even if you do not own a Samsung smartphone, you can use Samsung Pay by purchasing such a watch. The main thing is that your device works on Android 4.4 and above. You need to install the Samsung Gear application on your phone, through which the watch will be tied to your smartphone.

After completing the payment, you will feel a vibrating alert, and then you will receive a receipt, as with a regular purchase in cash or by bank card.
