The Difference of ID Card, IC card, CPU card & M1 Card
The ID card is called the Identification Card. It is a non-writable proximity card with a fixed number, mainly SYRIS's EM format in Taiwan, and HIDMOTOROLA in the United States. Like as magnetic card, the ID card only uses the "card number". In addition to the card number, the card has no security function, and its "card number" is open and bare, So the ID card is "inductive magnetic card." The specification of the ISO standard ID card is: 85.5x54x0.80±0.04mm (height/width/thickness). There are also some thick, thin or special cards on the market.
An IC card with a memory is also called a memory card or a memory card. An IC card with a microprocessor is also called Memory card or smart card. Memory cards can store large amounts of information; smart cards not only have memory capabilities but also have the ability to process the information.
The IC card can store car expenses, telephone charges, subway ride fees, canteen dining expenses, highway tolls, shopping tours, and trade services conveniently. Another kind of card with similar function to IC card is called M1 card. M1 is the abbreviation of chips produced by NXP, a subsidiary of Philips. At present, the company's M1 chip is compatible with domestic chips. In fact, M1 card also belongs to non-contact IC. card.
M1 card, the advantage is a multi-function card, can be read and write, the disadvantage is: the price is a little expensive, sensing distance is short, suitable for non-fixed consumption system, parking system, access control and attendance systems.
You can choose CPU card, CPU card chip is a microprocessor, If you want to achieve more advanced features and the security level is particularly high, its function is equivalent to a microcomputer. CPU cards can be applied to many fields such as finance, insurance, traffic police, and government industries etc.
The advantage of the CPU card is the characteristics of large storage space, fast reading speed, support for multiple functions of one card, etc. The CPU card is not much different from the ordinary IC card and RF card in appearance, but its performance is greatly improved, compared with ordinary IC cards, the number of cards is increased. Generally, the CPU card contains random number generators, hardware DES, 3DES encryption algorithms, etc., and the COS operating system on the CPU card chip can achieve a financial-grade security level.
