Key Features:

 

  • MIsmartApp (Delegated Application Management)
  • Memory reuse in DAM applications (Format Application)
  • Transaction MAC on application level
  • Multiple Key Sets per application with fast key rolling mechanism (up to 16 sets)
  • Accessing files from any two applications during a single transaction
  • Multiple keys assignments for each file access right (up to 8)
  • Virtual Card Architecture for enhanced card/application selection on multi-VC devices with privacy protection
  • Proximity Check for protection against Relay Attacks
  • Originality Check for proof of genuine NXP’s product
  • New EV2 Secure Messaging based on AES (similar with MIFARE Plus’s secure messaging)

Chip type optional:

    MIFARE DESfire EV1 2K (D21)

    MIFARE DESfire EV1 4K (D41)

    MIFARE DESfire EV1 8K (D81)

    MIFARE DESfire EV2 2K (D22)

    MIFARE DESfire EV2 4K (D42)

    MIFARE DESfire EV2 8K (D82)

 

 

MIFARE DESFire EV2 contactless IC is the third generation of the MIFARE DESFire series product, which features fast and highly secure data transmission and flexible application management. It is functionally backward compatible with both MIFARE DESFire EV1 and MIFARE DESFire D40 (MF3ICD40) and it can hold as many different applications as the memory size supports.

 

Compared to MIFARE DESFire EV1 a MIFARE DESFire EV2 chip can hold as many different applications as the memory size supports and new applications can be loaded after the card has been deployed into the market. A purse can even be shared between applications, for greater interoperability.
