MIFARE® DESFire EV1

 

MIFARE DESFire EV1 contactless IC card 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 the mutual three-pass authentication, a MIFARE DESFire EV1 card can hold up to 28 different applications and 32 files per application. An automatic anti-tear mechanism is available for all file types, which guarantees transaction oriented data integrity.

 

It is fully complies with the requirements for fast and highly secure data transmission, flexible memory organization and interoperability with existing infrastructure.

 

Key Features:

 

  • Operating frequency: 13.56 MHz
  • Compliant with ISO/IEC 14443 Type A standard
  • Momery optional with 2KB, 4KB, 8KB
  • Up to 28 applications simultaneously on one PICC
  • Up to 32 files in each application
  • Support to create standard data file, back-up data file, value file, linear record file and cyclic record file
  • Mutual three pass authentication
  • Support DES/3DES/AES encryption algorithm
  • Authentication on application level, 1 card master key and up to 14 keys per application
  • Optional “RANDOM” ID for enhance security and privacy
  • Transaction oriented automatic anti-tear mechanism

 

 

MIFARE® DESFire EV2

 

MIFARE DESFire EV2 contactless card 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.

 

 

New features on MIFARE® DESFire EV2

 

  • 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)
