NXP MIFARE® DESFire® EV3 Chip

The newest chips in the market in 2020!

Based on open global standards for both RF interface and cryptographic methods, our MIFARE DESFire product family provides highly secure microcontroller-based ICs. Its name DESFire references the use of DES, 2K3DES, 3K3DES, and AES hardware cryptographic engines for securing transmission data.

This family is ideally suited for solution developers and system operators building reliable, interoperable, and scalable contactless solutions. MIFARE DESFire products can be seamlessly integrated into mobile schemes and support multi-application smart card solutions in identity, access control, loyalty, and micropayment applications, as well as in transport ticketing installations.Featured Products

The features of the MIFARE DESFire EV3 IC reflect NXP’s continued commitment to secure, connected and convenient contactless Smart City services. As part of the MIFARE DESFire family, the latest family member combines enhanced performance with a greater operating distance and improved transaction speed compared to its predecessors, including:

  • IC hardware and software certification according to Common Criteria EAL 5+
  • Broad choice of open crypto algorithms based on DES, 2K3DES, 3K3DES, or AES
  • SUN message authentication for advanced data protection
  • Transaction Timer to mitigate man-in-the-middle attacks
  • Seamless integration of mobile services in combination with MIFARE 2GO
