Samsung Pay uses leading edge tokenization and authentication methods to secure payment information. Samsung Pay also uses biometrics as a security measure, enabling users to authenticate Samsung Pay via fingerprint or Secured PIN. In addition to the security measures implemented by Samsung Pay, Samsung’s KNOX service constantly monitors suspicious activity within the device to protect from any malicious attacks
Tokenization is a method of replacing your sensitive payment card information (Card Number, Expiration Date, Security code, etc.) with a device-specific ‘Token’ which acts as a surrogate value. In mobile payments, Tokens are used to protect payment information and to reduce the security risks inherent to plastic cards.
