MIFARE DESFire EV1 vs ICODE SLIX2

MIFARE DESFire EV1 offers 2-8 KB memory with 3DES + AES-128 security, making it ideal for transit, campus cards, access control. ICODE SLIX2 provides 2560 bits with 64-bit password security, suited for library management, industrial tracking, pharmaceutical.

MIFARE DESFire EV1 vs ICODE SLIX2

DESFire EV1 is a secure proximity card chip for credential applications. ICODE SLIX2 is a vicinity item-tracking chip. They operate on different RF protocols, serve different industries, and are not substitutes for each other.


Overview

MIFARE DESFire EV1: ISO 14443-4, AES-128 / 3DES, 2–8 KB, 0–10 cm range, NFC-A. Designed for secure access control, transit, and campus card credentials.

ICODE SLIX2: ISO 15693 (NFC-V), 320 bytes, 64-bit password, EAS function, up to 1 m range. Designed for item-level tracking, library management, and pharmaceutical serialization.


Key Differences

  • Protocol: DESFire EV1 uses ISO 14443-4 (NFC-A). ICODE SLIX2 uses ISO 15693 (NFC-V). Readers must explicitly support the target protocol.
  • Security: DESFire EV1 provides 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 — sufficient for basic write protection, not for strong authentication.
  • Range: DESFire EV1 operates within 10 cm. SLIX2 reads at up to 1 m.
  • Memory: EV1 (8 KB) vs SLIX2 (320 bytes).
  • EAS: SLIX2 includes an Electronic Article Surveillance function for anti-theft detection. DESFire EV1 has no equivalent.
