What are the connections and differences between IC card, M 1 card, CPU card, SAM card and PSAM card?

IC card: IC card is the full name of Integrated circuit card (integrated? Circuit? Card), also known as? Smart card (smart? Card). Read and write, large capacity, encryption function, reliable data recording, more convenient to use, such as all-in-one card system, consumer system, etc. ? France Roland? It was invented by Moreno in 1970. 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.

M 1 card: M 1 chip refers to the abbreviation of the chip produced by NXP, a subsidiary of Philips. The Mifare 1 series commonly used in S50 and S70 models has been compatible with domestic chips by 20131.4.

M 1 chip and induction antenna are encapsulated by PVC, and then the card made by pressing molding is the M 1 card in smart card industry, which belongs to non-contact IC card.

CPU card: CPU card: also known as smart card. The integrated circuit in the card includes microprocessor CPU, storage unit (including RAM, program memory ROM(FLASH), user data memory EEPROM) and chip operating system COS. The CPU card with COS is equivalent to a microcomputer, which not only has the function of data storage, but also has the functions of command processing and data security protection. There is an operating system that can store data and has its own ID number. The CPU card sends a string of data to the device, and the device performs operations with the SAM card. The device sends another string of data back to the CPU card for confirmation, and then carries out transaction or identity authentication.

SAM card (secure access? Module):? It is a special CPU card; Stored keys and encryption and decryption algorithms.

At present, there are many kinds of SAM cards:

PSAM card: terminal security control module, generally used for small payment deduction;

ESAM: SAM card of the manufacturer (system) for equipment certification;

ISAM: used for charging;

PSAM card (purchase? SecureAccess？ Module): point-of-sale terminal security access module? , embedded in all kinds of terminal equipment, to provide them with 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, network terminal, direct connection terminal 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.

-the above comes from the network.

IC card, card with integrated circuit chip

Cpu card, advanced IC card, with CPU microprocessor in the chip, used for payment verification, with high security.

When the CPU card interacts with the terminal, the PSAM card is used. PSAM is embedded in the terminal and plays an authentication role. For example, our bus card is a CPU card, and the terminal of bus card swiping is equipped with PSAM. When swiping a card, we can verify whether the card is a bus card, and then deduct the balance. Everyone can only take the bus if they buy a bus card at the authorized outlets of the bus company. At the same time, only the legal equipment allocated by the bus company can deduct money from the bus card.
