What technology does Samsung Pay use?

Samsung Pay Use

Samsung Pay uses NFC and MST technologies.

Near Field Communication (NFC) allows two devices placed within a few inches of each other to exchange payment information. For Magnetic Secure Transmission (MST), a magnetic signal is sent from a compatible device to the payment terminal’s card reader (to emulate swiping a physical payment card).

Samsung Pay uses both NFC and MST to send payment information to the terminal. The transaction is seamless, whether using NFC or MST, allowing for a better user experience.

Both technologies are equally secure, using a unique digital card number in place of your actual card number. Your information is kept private and secure, and only your bank and the card's payment network will have information on the transaction.
