The unique MIFARE RF (Radio Frequency) non-contact interface standard of Mifare 1 RF Card has already been adopted as an international standard - ISO/IEC 14443 TYPE A. The standard operational range of an RF card is 100mm (with MCM500 as the core module of the reader) and 25mm (with MCM200 as the core module of the reader). The communication rate with the card reader is 106k bits/s. Mifare 1 IC (RF) Card has an advanced data communication encryption system and a two-way verification password system. It provides protection against overlap by simultaneously processing multiple cards that overlap in the effective working range of the card reader antenna.
