## FAQ
- Q: Does wearing the RFID watch on the wrist affect read range?
  A: Yes — the human body is ~80% water and water dielectric loading detunes a 13.56 MHz antenna, reducing range by 30-50% if not compensated. Our watch antenna designs are tuned on a phantom wrist (ASTM F2182 tissue-equivalent gel) plus live on-wrist validation so the assembled watch resonates at 13.56 ± 0.3 MHz in use. Result: DESFire EV3 watch tag worn on wrist reads at 2-4 cm on standard ISO/IEC 14443 readers, which is sufficient for tap access.
- Q: Can guests keep the RFID watch as a souvenir?
  A: Yes, and many resorts and parks design their RFID watches specifically as branded souvenirs that guests take home. The NFC chip can be programmed with an NDEF URL that opens a memory page, photo gallery or return-visit booking page when tapped on a phone. Turning the souvenir into an ongoing marketing touchpoint. For programs with meaningful stored-value (room charges, spa bookings) prefer DESFire EV3 AES-128 over NTAG so balances survive the trip home securely.
- Q: What is the MOQ and lead time?
  A: RFID watch tags with silicone band and custom branding: MOQ 300, lead time 18-22 business days (includes watch case mold setup if custom shape). Stock round watch case with silicone band in standard colors: MOQ 100, lead time 10-12 business days. Chip encoding and UID management included in standard production.
- Q: Which chip is right for a resort all-inclusive program?
  A: DESFire EV3 with AES-128 is the current reference. It supports authenticated room-access, protected value files for on-watch restaurant/spa/activity charges, and tamper-evident transaction counters for reconciliation. MIFARE Classic 1K is still offered by some legacy suppliers but the CRYPTO-1 cipher has been publicly broken since 2008 — deploying it in a new resort program exposes the operator to counterfeit-credential fraud. NTAG215/216 is fine for pure souvenir/NDEF-URL use cases but does not provide authenticated access control.
- Q: Is the silicone band safe for guests with latex or nickel allergies?
  A: Yes. Our default silicone is platinum-cured medical-grade silicone (polydimethylsiloxane) — latex-free, BPA-free, phthalate-free and passes ISO 10993-5 cytotoxicity and ISO 10993-10 irritation testing. For nickel-sensitive guests, specify 316L stainless steel for all band hardware (buckle, lugs) rather than nickel-plated steel; the upcharge is nominal and eliminates a common rash complaint.
