## FAQ
- Q: What is the difference between ICODE SLIX and NFC (ISO/IEC 14443)?
  A: Both operate at 13.56 MHz but use different air-interfaces. ISO/IEC 14443 (NFC) is short-range (5–10 cm), single-card selection — the transit, building-access and payment interface. ISO/IEC 15693 (ICODE SLIX) is vicinity (30 cm – 1 m), slotted-ALOHA anti-collision — the library, inventory and shelf-sweep interface. Most Android phones with NXP controllers read both; iPhone 7+ on iOS 14+ reads both via Core NFC, but the phone antenna limits 15693 to 1–3 cm. Dedicated ISO/IEC 15693 readers achieve the full range.
- Q: Can ICODE SLIX cards be read by NFC phones?
  A: Yes, on Android with NXP NFC controllers (PN544 onward) via android.nfc.tech.NfcV and on iPhone 7+ with iOS 14+ via Core NFC ISO15693ReaderSession — but only at 1–3 cm because the phone antenna is small. For library-gate (30 cm) and shelf-sweep (50 cm – 1 m) ranges you need a dedicated ISO/IEC 15693 reader such as FEIG ID ISC.LR2500 or Bibliotheca / D-Tech workstation kits.
- Q: How does SLIX compare to SLIX2, and when is the upgrade worth it?
  A: SLIX2 adds 2,528 bits of user memory (vs 896), privacy mode that stops arbitrary readers enumerating the UID, an originality signature and per-block password protection. For ISO 28560-2 library deployments SLIX is usually sufficient. SLIX2 is worth the premium when the programme has a privacy obligation under GDPR / EU DPA guidance, stores extended item metadata that does not fit 896 bits, or needs chain-of-custody signatures on document-tracking cards.
- Q: What is the MOQ and lead time?
  A: Blank white ICODE SLIX cards: MOQ 200, lead time 5–7 business days. SLIX2 cards at the same MOQs with a modest per-card premium. Custom-printed cards with pre-encoded AFI / DSFID / user-data blocks: MOQ 500, lead time 12–15 business days from artwork approval — the extra time is for the pre-encoding sample pass against the customer's ILS vendor reference reader.
