General Description

MIFARE DESFire EV2 (MF3D(H)x2) is the latest addition to the MIFARE DESFire product family introducing new features along with enhanced performance for best user experience. The MIFARE DESFire EV2 is Common Criteria EAL5+ security certified which is the same security certification level as demanded for smart card IC products used e.g. for banking cards or electronic passports. It fully complies with the requirements for fast and highly secure data transmission and flexible application management. This makes it the ideal product for service providers and service operators who want to offer aneasy, convenient and secure access to a wide variety of different services.

MIFARE DESFire EV2 is the third generation of the MIFARE DESFire products family succeeding MIFARE DESFire EV1. It is functionally backward compatible with both MIFARE DESFire EV1 and MIFARE DESFire D40 (MF3ICD40).

MIFARE DESFire EV2 can be used as a MIFARE DESFire EV1 in its default delivery configuration. Every new features would required an activation and/or the use of new commands.
