SLE4428/SLE5528 Contact IC Card
SLE4428/SLE5528 Contact IC Card

 1.Contact IC Card is short for Integrated Circuit Card, with an integrated circuit chip that can store, encrypt and process data sealed on a plastic card.The shape and size follow ISO 7816 standard. The chip is normally used uneasily volatile memory (like ROM and EEPROM), protection logic circuit or even with a micro processor 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 

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

4.Main features of contact IC card

1)Large storage capacity 2) Safe and secure 3) Small size, light weight 4) Good anti-interference ability, easy to carry and use. 4) Long service life. 5)Doesn’t have much demand 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
