CR80 Printable Contact Smart IC Card SLE4442
A smart card is a device that includes an embedded integrated circuit that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. The card connects to a reader with direct physical contact or with a remote contactless radio frequency interface. With an embedded microcontroller, smart cards have the unique ability to store large amounts of data, carry out their own on-card functions (e.g., encryption and mutual authentication) and interact intelligently with a smart card reader. Smart card technology conforms to international standards (ISO/IEC 7816 and ISO/IEC 14443) and is available in a variety of form factors, including plastic cards, key fobs, watches, subscriber identification modules used in GSM mobile phones, and USB-based tokens.

SLE4442 is the most common chip that used in security area. SLE 4442 provides a security code logic which controls the write/erase access to the memory. For this purpose the SLE 4442 contains a 4-byte security memory with an Error Counter EC (bit 0 to bit 2) and 3 bytes reference data. These 3 bytes as a whole are called Programmable Security Code (PSC). After power on the whole memory, except for the reference data, can only be read. Only after a successful comparison of verification data with the internal reference data the memory has the identical access functionality of the SLE 4432 until the power is switched off. After three successive unsuccessful comparisons the Error Counter blocks any subsequent attempt and hence any possibility to write and erase.
