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 15693ISO 15693Standard for vicinity-range smart cards, 1+ meter read rangeView full → vicinity tag for item-level logistics. Different RF protocols, different industries.
Overview
MIFARE DESFire Light: ISO 14443ISO 14443Standard for contactless smart cards at 13.56 MHz (Types A and B)View full →-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 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 →. SLIX2 provides a 64-bit password — no mutual authentication.
- Range: DESFire Light: 0–10 cm. SLIX2: 0–100 cm.
