The way from the use of IC cards is divided into two types:

(1) Contact IC card: must be plugged into a mount IC card, card reader, through a wire to transmit data of a IC card details are as follows:

A: Siemens: SLE4442 card, 5542 card, 7442 card, 4428 card, 5528 card, 7428 cards, etc.;

B: Fudan University: FM4442 card, 5542 card, 7442 card, 4428 card, 5528 card, 7428 card, FM24C02 cards, FM24C04 cards, FM24C08 cards, FM24C16 cards, FM1108 cards, etc.;

C: ISSI: IS4442 card, 5542 card, 7442 card, 4428 card, 5528 card, 7428 card, IS24C02 cards, IS24C04 cards, IS24C08 cards, IS24C16 cards, etc.;

D: Bei Ling: BL4442 card, 5542 card, 7442 card, 4428 card, 5528 card, 7428 card, BL24C02 cards, BL24C04 cards, BL24C08 cards, BL24C16 cards, BL1108 cards, etc.;

E: Atmel (atmel): a common non-encrypted data card: AT24C01A, AT24C02, AT24C04, AT24C08, AT24C16, AT24C32, AT24C64, AT24C128, etc., common logic, memory card encryption: AT88SC102, AT88SC1604, AT88SC1608, AT88SC153 and so on.

(2) non-contact IC card (radio frequency card): Host-free bayonet, IC card and the host without contact will be able to wirelessly transmit data through an IC card (such as the M1 card, MF1 Card, S50 cards, S70 Card , UTRLIGHT ultra-thin cards, ID cards, TK4100 card, T5557 card, T5567 card, CPU cards, etc.). Because of its overall package, not afraid of oil and wear, so long service life.

  IC card is divided into three kinds of their functions:

(1) memory card.

(2) with a cryptographic logic, memory card: There COS (Card Operating System) is a memory card.

(3) CPU smart cards: A set of CPU (central processing unit) of a memory card.

It is divided into three kinds of cards are both contact and contactless.

  Non-contact type IC card is also called radio frequency card, proximity card. On the card containing a tiny integrated circuit chip and coil. Corresponding to the card reader within a table or a set of circuits, such as the one to transmit and receive radio signals of micro-radio station. When the radio card work, the first in a very short moment, by the card table in the radio frequency electromagnetic waves emitted by electromagnetic induction card to form a low-voltage power supply, RF card also turned into a mini-radio stations, with the card table to conduct a series of complex high-speed data exchange and messaging, instant, the data that the exchange is completed.

   Radio frequency card is through radio frequency signals to transmit data, and its life expectancy depends largely on the life of chips. The contact-type IC card chip, the service life depends not only on life, and depends mainly on the life of the card. Because of its repeated contact plug, and some poor quality products, insert a few will not damage the chip integrated circuits. The RF card without contact and friction, so relatively speaking, radio frequency card much longer life span
