Secure Access Module (SAM) is based on SmartCard Integrated circuits and is designed as a general cryptogram computation module or as a security authentication module to enhance the security and cryptography performance in devices, commonly in devices needing to perform secure transactions, such as paying terminals. It can be used for cryptographic computation and secure authentication against smart cards or contactless EMV cards. Physically a SAM card can either be a SIM card and plugged into a SAM slot in a reader, or a fixed integrated circuit in a housing directly soldered on a Printed circuit board.
