Engineering Brief

The MIFARE DESFire Light is an entry-level contactless IC targeting cost-sensitive closed-loop applications requiring strong security. It features AES-128 and 3DES encryption with 448 bytes of user-configurable memory organized in a flexible ISO/IEC 7816-4 file system. The chip supports transaction MACs, encrypted communication, and NXP's Originality Signature for anti-counterfeiting, making it suitable for access control, transit, loyalty, and event applications where interoperability with the broader DESFire ecosystem is desired at a lower price point.

Typical Applications

  • Access control and building management
  • Public transportation ticketing
  • Loyalty and membership programs
  • Event ticketing and cashless payment
  • Campus ID cards
  • Closed-loop payment systems
