## FAQ
- Q: How does the tamper-evident mechanism work electronically?
  A: The NFC antenna is printed or etched on a brittle substrate that fractures when peel force is applied. When the antenna circuit breaks, the NFC chip can no longer harvest energy from the reader's RF field, so it becomes permanently unresponsive. A genuine sealed label responds to an NFC tap; a tampered label does not. This binary alive / dead status is impossible to fake — you cannot repair a fractured printed antenna.
- Q: Can the NTAG 424 DNA chip prevent sophisticated cloning attacks?
  A: Yes. The NTAG 424 DNA chip generates a unique, rotating SUN (Secure Unique NFC) message code with every tap, using AES-128 cryptographic keys stored in the chip's secure memory. Even if an attacker intercepts one tap's data, the code changes on the next tap. The cloud server validates the rotating code, detecting replay attacks and cloned UIDs immediately. This is the highest level of NFC authentication available.
- Q: What happens if the label is damaged accidentally (not tampered)?
  A: Accidental damage that fractures the antenna will trigger the same tamper-evident response — the chip becomes unreadable. This is by design — the system errs on the side of security. Products with accidentally damaged labels can be verified through alternative channels (batch / lot lookup, customer service) and relabelled by authorised personnel. The false-positive rate from accidental damage in normal handling is typically under 0.1%.
- Q: Can I use tamper-evident NFC labels to satisfy FDA DSCSA and EU FMD anti-tampering requirements?
  A: NFC labels alone are not an approved serialisation data carrier for FDA DSCSA or EU FMD; both regulations require a printed 2D data matrix (GS1 DataMatrix or EAN-13 equivalent) as the serialisation carrier. NFC tamper-evident labels satisfy the separate EU FMD anti-tampering device (ATD) requirement under Delegated Regulation (EU) 2016/161, Article 5 — the ATD is independent of the serialisation data carrier and must clearly signal tampering on the pack. Most EU pharma programmes combine a printed 2D DataMatrix (serialisation carrier) with a tamper-evident NFC or adhesive seal (ATD); the NFC layer adds patient-facing authentication and supply-chain anomaly detection value beyond ATD compliance.
- Q: How long does the tamper-evident seal retain its function in storage?
  A: Shelf life of the unapplied label is 12 months under standard warehousing conditions (15-25 °C, <60% RH). The NFC chip itself has >10-year data retention and >100,000 write-cycle endurance per NXP datasheet. Once applied to the finished product, the tamper-evident function remains active for the product's shelf life provided the pack stays within the label's rated environmental envelope: standard PET face stock is rated −25 to +70 °C; for cold-chain pharma (<−20 °C) specify a low-temperature adhesive variant, and for high-temperature supply-chain (>70 °C industrial spare parts) specify a high-temperature polyimide face stock. Field reports on wine-bottle capsule seals show 5+ year tamper-function retention in typical wine-cellar storage (10-18 °C).
