Magnetic Secure TransmissionTM 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. .

Near Field Communication or NFC is a method of wirelessly transmitting data using radio waves. Samsung Wallet uses NFC to wirelessly transmit payment data to payment terminals with NFC readers that have been activated for use.

For Samsung Wallet, 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 Wallet the most accepted mobile payment service on the market.

In the context of Samsung Wallet, MST and NFC have the same level of security. The payment information transmitted by both MST and NFC is protected using tokenization. .

The device must be placed within 5cm of the card reader in order for MST to work.

The fingerprint scanner is very accurate. It has a “False-Acceptance Rate” less than .00002%.
