NXP has developed the Mifare MF1 IC S50 to be used in contactless smart cards according to ISO/IEC 14443A. The Communication layer (Mifare RF Interface) complies to part 2 and 3 of the ISO 14443A standard. The security layer sports the field proven CRYPTO1 stream chiper for secure data exchange of the Mifare Classic family.The Mifare MF1 IC S50 is connected to a coil with a few turns and then embedded in plastic to form the passive contactless smart card. No Battery is needed. When the card is positioned in the proximity of the READ WRITE device antenna, the hig speed RF communication allow to transmit data with 106 kBits/second.
