The difference between psam card and ic card

1, PSAM (purchase of secure access module): the secure access module of the point-of-sale terminal is embedded in various terminal devices to provide IC card-level security protection. SAM has not only the function of user card, but also the function of calculation. PSAM has added a calculation key. Scope of application PSAM is mainly used for commercial POS, outlet terminals, direct connection terminals and other equipment. It has security control and management functions, supports multi-level card issuing mechanism, and is suitable for multi-application environment. Including ordinary PSAM cards and high-speed PSAM cards.

2.IC card is the full name of integrated circuit card, also known as smart card.

In the same year, Japanese inventor KunitakaArimura obtained the first smart card patent, which has a history of nearly 40 years. With the development of VLSI technology, computer technology and information security technology, smart card technology is becoming more and more mature and widely used. IC card refers to a card that encapsulates an integrated circuit chip in a plastic substrate. It is an electronic card with various functions and wide uses. The substrate of the card is made of PVC hard plastic and contains integrated circuit chips. Because the English abbreviation of integrated circuit is IC, it is called IC card. It can be connected with various terminal devices and has multiple functions. The popular name of general contact IC card is IC card.
