Farpointe Data has migrated to MIFARE DESFire EV1, the next generation of smart card technology by NXP Semiconductors, in its line of Delta smart cards. Access control system manufacturers, integrators and dealers will be able to tout greater security over MIFARE Classic smart cards because MIFARE DESFire EV1 uses 128 AES encryption, the same as used by the U.S. federal government. MIFARE DESFire EV1 is based on open global standards for both air interface and cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A and uses optional ISO/IEC 7816-4 commands.
Featuring an on-chip backup management system and mutual three pass authentication, a MIFARE DESFire EV1 card can hold up to 28 different applications and 32 files per application. The size of each file is defined at the moment of its creation, making MIFARE DESFire EV1 a truly flexible and convenient product platform. Additionally, an automatic anti-tear mechanism is available for all file types, which guarantees transaction oriented data integrity. With MIFARE DESFire EV1, data transfer rates up to 848 kbit/s can be achieved, allowing fast data transmission.
