ICODE SLIX2: ISO 15693ISO 15693Standard for vicinity-range smart cards, 1+ meter read rangeView full → (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 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 — 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.
