## FAQ
- Q: How does the label detect if the bottle has been opened or refilled?
  A: NFC antenna is designed as a bridge spanning the bottle cap and neck. When cap is twisted or removed, the antenna trace permanently breaks. On next NFC scan, chip either fails to respond (antenna fully broken) or responds with 'tampered/opened' status code (TT variant). Provides physical proof that bottle closure has been disturbed. The mechanism defeats the 'genuine bottle refilled with inferior product' attack that bypasses tax-stamp verification.
- Q: Can a counterfeiter clone the NFC chip?
  A: No. NTAG 424 DNA contains factory-programmed secret cryptographic keys that generate a unique time-based digital signature with every tap. Keys cannot be extracted from chip; signature algorithm cannot be reproduced without them. Even with physical access to a genuine chip, a counterfeiter cannot produce a second chip that generates valid signatures. Replay attacks fail because each tap's URL contains a monotonically increasing counter; brand backend rejects URLs with previously-seen counter values.
- Q: Does the consumer need to download an app to verify the bottle?
  A: No — tapping the NFC label with any NFC-enabled smartphone (iPhone XS+ iOS 14+ or Android with NFC) opens a mobile web page directly in the browser. Page displays verification status (authentic / counterfeit / opened), bottle details, GI-protected provenance, tasting notes, cocktail recipes. No app download or account creation required. Branded page auto-localises by phone locale for travel-retail / duty-free.
- Q: Can NFC authentication coexist with government-mandated tax stamps or duty stamps?
  A: Yes — two layers solve different problems and are complementary. Government duty stamps (HMRC UK DS5, EU member-state under 92/83/EEC, Russian EGAIS, US TTB strip-stamps where applicable) attest excise duty paid — they're a fiscal control, not authenticity guarantee, and themselves counterfeited by sophisticated operations. NFC authentication label sits on top as cryptographic bottle-level authenticity layer with tamper-evident opening detection. Most brand programmes place NFC on cap/neck bridge so it doesn't interfere with regulator tax-stamp placement on bottle neck or main label area.
- Q: How does per-bottle serialisation help with age-stated whisky and rare-expression counterfeiting?
  A: Age-stated whisky (18, 25, 30-year), vintage cognac, rare limited-release expressions carry the highest counterfeit premium globally — a 25-year single malt commands 10-30× retail price of standard expression. Per-bottle NFC serialisation records cask number, bottling date, master-blender signoff, proof, and (for GI-protected spirits) producing distillery's appellation certification at bottling. On consumer tap, backend verifies bottle serial against master-bottling database and displays full per-bottle provenance. Counterfeiters cannot reuse a serial (backend flags duplicate scans in geographically implausible locations); cannot fabricate a new serial (NTAG 424 DNA AES-128 cannot be reproduced without factory-provisioned secret key). Provides authentication assurance that secondary-market collector pricing has historically relied on paper certificates of authenticity to deliver.
- Q: Does the bridge-antenna NFC label survive standard bottling-line application?
  A: Yes — bridge-antenna geometry is adapted to standard cap shapes (screw-cap, cork-and-capsule, swing-top, T-cork) and applies on standard bottling-line equipment. No process change for the spirits producer. Premium-substrate label design (metallic foil, soft-touch laminate, embossed textures, hot-foil stamping) matches the aesthetic of high-end spirits packaging. Tag chip rated for cellar conditions across decades-aged whisky / vintage cognac (200,000 write cycles + 50-year retention per NXP datasheet).
