Pay confidently knowing each Samsung Pay transaction uses a unique randomized set of numbers to keep your card number secure and is authenticated by your fingerprint, PIN number or iris scan. When the phone is held against the terminal, the phone emits a magnetic signal that works like the magnetic strip found on the back of your card to complete the purchase.Ĭhecking out with Samsung Pay is fast inside mobile apps – just select Samsung Pay at checkout and authenticate the purchase with your fingerprint, PIN number or iris scan.
NFC technology communicates with the contactless/NFC compatible terminals while MST works with most all magnetic strip only terminals. Samsung Pay uses near-field communication (NFC) technology AND magnetic secure transmission (MST) to process payments. Samsung Pay allows you to pay at merchants that do not accept contactless payments because it makes payments two ways. Using your Gear smartwatch, long press the Back key to bring up Samsung Pay. Using your smartphone, open Samsung Pay by swiping up on your screen and authorize the payment with your fingerprint, PIN or iris scan. Simply hold your Samsung smartphone or Gear smartwatch near the merchant’s card reader.
