Professional Build ic Card

A: the technical data:

IC card from its use methods are divided into two kinds:

(1) contact IC card: must IC card plugs into a bayonet, card reader inside, through the cable way to transmit data to a kind of IC card. Such as 4442 card, SLE4442 card, Siemens 4442 card, contact 1 c card, Internet card, 4428 CARDS, 5542 CARDS, 7442 CARDS, 24 c02 card, 24 c04 card, 24 c08 card.

(2) the non-contact IC card (induction card) : host no bayonet, IC card without and host contact, through the wireless way can transmit data of a kind of IC card (such as M1 card, S50 card, S70 card, T5557 card, T5567 card, CPU card). Because of its for the whole package, not afraid of oil pollution and wear, so long service life.

IC card from its function is divided into three kinds:
(1) memory card.
(2) with encryption logic memory card: there were COS (card operating system) of a memory card.
(3) CPU smart card: there were CPU (central processing unit) of a memory card.
These three card and are divided into contact and non-contact.
Non-contact IC card also called radio frequency card, induction card. In the card hidden inside tiny integrated circuit chip and coil. Corresponding card table or card reader in a circuit, such as seat can transmit and receive wireless signal miniature station. When radio frequency card work, first in a very short in the moment, the card table emission electromagnetic wave in the radio frequency card in electromagnetic induction to form a low voltage power supply, radio frequency card also become a tiny radio, and the card table high speed on a series of complex data exchange and information transfer, instant, data exchange is finished.
Rf card is through the radio frequency signal to transfer data, its life depends mainly on the life of the chip. And contact IC card life depends not only on the life of the chip, and mainly depends on the life of the card. Because of its contact repeated plug, some poor quality products, put a few times will damage the integrated circuit chip. And radio frequency card without contact and friction, so relatively speaking, radio frequency card's life is much longer
