MIFARE DESFire EV3 vs ICODE SLIX2
DESFire EV3 is a high-security proximity card chip for credential applications. ICODE SLIX2 is a vicinity item-tracking chip for logistics and library management. Different RF protocols, different industries, not interchangeable.
Overview
MIFARE DESFire EV3: ISO 14443ISO 14443Standard for contactless smart cards at 13.56 MHz (Types A and B)View full →-4 (NFC-A), AES-128, SDM, Proximity Check, 2–32 KB, 0–10 cm. NXP's current flagship secure card IC.
ICODE SLIX2: ISO 15693ISO 15693Standard for vicinity-range smart cards, 1+ meter read rangeView full → (NFC-V), 320 bytes, 64-bit password, EAS, up to 1 m range. Dominant in library RFID and pharmaceutical item tracking.
Key Differences
- Protocol: EV3 uses ISO 14443-4 (NFC-A). SLIX2 uses ISO 15693 (NFC-V).
- Security: EV3 provides AES-128 authenticationauthenticationIdentity verification of NFC tags/readers via passwords or cryptographyView full →/" 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 authenticationmutual authenticationTwo-way identity verification between reader and tagView full → with relay attack protection and SDM. SLIX2 provides a 64-bit password — no mutual authentication.
- Range: EV3 operates within 10 cm. SLIX2 operates at up to 1 m.
