4428/5528 chip cardThe SLE4428 is a standard, low-cost EEPROM memory smart card 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. SLE4428 is now replaced with SLE5528. SLE5528 is 100% functional compatible to SLE 4428.
