Access control system inside the IC card, ID card, M1 card, CPU card What is the difference between them?
???IC card, also known as integrated circuit card, it is the size and common credit card on the same plastic card embedded in one or more integrated circuits. The integrated circuit chip can be either a memory or a processor. IC card with memory, also known as memory card or memory card, with a microprocessor IC card, also known as smart card or smart card. Memory card can store a lot of information; smart card is not only has the memory ability, but also has the function of dealing with information. IC card can be very convenient to save the car fee, telephone charges, subway ride, canteen dining fees, road to pay and shopping travel, trade services.
CPU card chip is popular means that the chip contains a microprocessor, its function is equivalent to a microcomputer. People often use the integrated circuit card (IC card) on the metal chip is the CPU card chip. CPU card can be applied to finance, insurance, traffic police, government and other fields, with user space, read speed, support a card and other features, and has been through the People's Bank of China and the National Chamber of Commerce certification. CPU card from the appearance and the general IC card, the RF card is no difference, but the performance has a huge upgrade, security and general IC card than to improve a lot, usually CPU card contains random number generator, hardware DES, 3DES Encryption algorithm, with the operating system that is on-chip OS, also known as COS, you can achieve the financial level of security level.
????M1 card is a subsidiary of Phillips NXP produced chip abbreviation, are currently compatible with domestic chips, are non-contact IC card. M1 card, the advantage is readable and writable multi-function card, the drawback is: the price is slightly expensive, the sensor distance is short, suitable for non-fixed consumption system, parking system, access control time and attendance system.
ID card is called ID card (Identification Card), is a non-writeable card, with a fixed number. Card number in the card before writing can not be changed, absolutely ensure the uniqueness and security of the card number. Card in the weak system as a general access control or parking system user identification, because the ID card without key security authentication mechanism, and can not write a card, and now the basic consensus within the industry ID card is not suitable for making a card, nor Appropriate to do the consumer system.
