  "faq": [
    {
      "question": "Can counterfeiters clone an NFC authentication tag?",
      "answer": "Not with cryptographic chips like NTAG424 DNA. The AES-128 key stored in the chip's secure memory cannot be extracted through any known attack. A counterfeiter can copy the tag's UID but cannot generate valid rolling authentication codes without the secret key."
    },
    {
      "question": "Do consumers need an app to verify product authenticity?",
      "answer": "No. NTAG424 DNA tags store a URL that opens in the phone's default browser. The verification happens on the brand's cloud server, and the result is displayed as a web page. No app installation is required."
    },
    {
      "question": "How much does NFC authentication add to product cost?",
      "answer": "NTAG424 DNA tags cost $0.15-$0.30 per unit at volumes of 10,000+. Including integration labor and cloud verification platform fees, total per-unit cost is typically $0.25-$0.50. For products with margins of $10 or more, the anti-counterfeiting ROI is strongly positive."
    },
    {
      "question": "Can the same NFC tag serve both authentication and marketing purposes?",
      "answer": "Yes. The verification landing page can include authentication status alongside product information, loyalty program enrollment, warranty registration and promotional content. This dual-purpose approach maximizes the value of each embedded tag."
    },
    {
      "question": "What happens if the cloud verification server goes down?",
      "answer": "If the server is unreachable, the phone will display a connection error. Best practice is to include a static fallback indicator (such as the tag UID) that consumers can reference against a published list, though this provides weaker assurance than real-time cryptographic verification."
    },
    {
      "question": "How do we manage AES-128 keys for NTAG 424 DNA at scale without exposing them?",
      "answer": "Use NXP's Trust Provisioning Service for chip-individual keys derived from Master keys held in FIPS 140-2 Level 3 HSMs at NXP's secure factory. Your verification backend only ever sees per-chip keys after they're written to silicon — the master never leaves the HSM. For brands that prefer to control key generation in-house, partner with a HSM-backed SaaS (Authena, Arianee, Kezzler, Scantrust) that performs key derivation and signing inside their HSM cluster. Avoid storing AES-128 keys in plaintext databases or application config; standard pattern is HSM-protected key vault with role-based access on the verify endpoint."
    },
    {
      "question": "Should we pick Authena, Arianee, Kezzler or build it ourselves?",
      "answer": "Volume and security maturity are the decisive variables. <100K units/year and limited security team: pick a SaaS — Authena and Arianee dominate luxury, Kezzler and Scantrust dominate FMCG/pharma, EON dominates textile + DPP. 100K-1M units/year: SaaS is still usually right but negotiate per-active-item pricing aggressively (target $0.05-0.15/item/year). >1M units/year with a mature security team and existing HSM infrastructure: a build-it-yourself stack on NXP TapLinx SDK + your own HSM-backed verify endpoint amortises better. Most brands underestimate the operational burden of HSM key management — if you don't already operate HSMs for payment or PKI, default to SaaS."
