1PCS Smart IC Cards SLE 4428 Chip Blank PVC Contact IC Cards

The SLE4428 is a standard, low-cost EEPROM memory smartcard with 1K bytes of available storage, with an irreversible write protection feature and a 2-byte programmable security code. Additionally to the above functions this version has a PSC verification logic. All the memory, except for the PSC, can always be read. The memory can be written or erased only after PSC verification. The error counter can always be written. After eight successive incorrect entries the error counter will block any subsequent attempt at PSC verification and hence any possibility to write and erase.
