Description:
NXP has developed the MIFARE® MF1 IC S20 to be used in contactess smart cards according to ISO/IEC 14443A. The communication layer (MIFARE® RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. The security layer sports the field proven CRYPTO1 stream cipher for secure data exchange of the MIFARE® Classic family.
This specification describes electrical, physical and dimensional properties of sawn wafers.
Features:
