MIFARE DESFire Light vs ICODE SLIX2

MIFARE DESFire Light offers 640 bytes memory with AES-128 + LRP security, making it ideal for transit tickets, loyalty, micro-payment tokens. ICODE SLIX2 provides 2560 bits with 64-bit password security, suited for library management, industrial tracking, pharmaceutical.

MIFARE DESFire Light vs ICODE SLIX2

DESFire Light is an AES-secured proximity ticket chip for single-application transit deployments. ICODE SLIX2 is an ISO 15693 vicinity tag for item-level logistics. Different RF protocols, different industries.


Overview

MIFARE DESFire Light: ISO 14443-4 (NFC-A partial), AES-128 + LRP, 640 bytes, 0–10 cm. Cost-optimized AES-secured single-application chip for disposable transit tickets.

ICODE SLIX2: ISO 15693 (NFC-V), 320 bytes, 64-bit password, EAS, up to 1 m range. Dominant in library and pharmaceutical item tracking.


Key Differences

  • Protocol: DESFire Light uses ISO 14443-4 (NFC-A). SLIX2 uses ISO 15693 (NFC-V).
  • Security: DESFire Light uses AES-128 authentication/" class="text-cyan-600 dark:text-cyan-400 underline decoration-dotted decoration-cyan-300 dark:decoration-cyan-700 underline-offset-2 hover:decoration-solid transition-colors">mutual authentication. SLIX2 provides a 64-bit password — no mutual authentication.
  • Range: DESFire Light: 0–10 cm. SLIX2: 0–100 cm.
  • EAS: SLIX2 includes Electronic Article Surveillance. DESFire Light does not.
  • Memory: DESFire Light 640 bytes; SLIX2 320 bytes.
  • Use case: DESFire Light is a transit ticket chip; SLIX2 is an item-tracking chip.
