Contact IC Card

 1.ContactIC Card is short for Integrated Circuit Card, with anintegrated circuit chipthat can store, encrypt and process data sealed on a plastic card. The shapeand size follow ISO 7816 standard. The chip is normally used uneasily volatilememory (like ROM and EEPROM), protection logic circuit or even with amicroprocessor CPU, which makes an IC card a real smart card.

2.Category of contact IC card: general memory card, logic encryption memory card,CPU card and super smart card

3.Read and write principle of contact IC card

ICcard and application system is connected through IC card reader and writer,which is called IFD (Interface Device) in the ISO international standard. TheCPU inside IFD identifies and activates the IC card inserted through theinterface circuit, and provides a stable power supply and clock signal to thecard through contact, and finally completes read and write operations throughparallel communication, half duplex serial communication or I2C communication withIC card.

4.Main features of contact IC card

1)Large storage capacity 2)Safe and secure 3)Small size, light weigh 4)Good anti-interferenceability, easy to carry and use. 4) Long service life. 5) Doesn’t have muchdemand for network, convenient to use in low network connection environment.

5.Specification of contact IC card

1)Standard card: size 85.5x54mm, thickness 0.9±0.05mm, can be offset printing,silk screen printing and digital printing

2)Other customized size
