SLE4428 Contact chip cards

SLE4428 chip is a standard, low-cost EEPROM memory smartcard with 1Kbyte storage space. It is a protected smart card that consists of 1,024 bytes of EEPROM memory. After eight successive incorrect entries the error counter will block any subsequent attempt at PSC verification and hence any possibility to write and erase. It is no doubt that gives a sense of secure for the users.

Reading of the whole memory is always possible, and the memory can be written and erased byte by byte.

The typical applications for the memory card includes access control, staff attendance, transport payment, personal identification,etc.
