Thank you for reaching out to the Samsung community! We would like to inform that Samsung pay uses MST and NFC technology for payment. MST-Magnetic Secure Transmission or MST, is a groundbreaking method of sending data using magnetic waves. MST replicates a card swipe by wirelessly transmitting magnetic waves from the supported Samsung device to a standard card reader. MST turns every card reader into a contactless payment receiver. NFC-Near Field Communication or NFC is a method of wirelessly transmitting data using radio waves. Samsung Pay uses NFC to wirelessly transmit payment data to payment terminals with NFC readers that have been activated for use.
For Samsung Pay, either MST or NFC technology can be used to make secure, contactless transactions. The key difference is that almost all merchants can accept MST, which makes Samsung Pay the most accepted mobile payment service on the market.
