  "faq": [
    {
      "question": "Can I mix Classic and DESFire cards in the same hotel?",
      "answer": "Yes, as long as each lock is configured to accept the chip type of the cards being issued for that zone. Many properties run DESFire on renovated floors and Classic on legacy wings during a phased migration. The PMS encoder must support both chip families and the front-desk agent needs a way to select the correct card type at check-in."
    },
    {
      "question": "Is MIFARE Classic still safe enough for hotel use?",
      "answer": "Classic's Crypto-1 encryption has known vulnerabilities, but real-world hotel card cloning attacks are rare because the attacker needs physical proximity and knowledge of sector keys. For budget-limited properties with low security risk, Classic remains functional. However, brand standards and insurance requirements increasingly mandate AES-level encryption."
    },
    {
      "question": "What is MIFARE Plus EV2 and when should I use it?",
      "answer": "MIFARE Plus EV2 is a bridge chip that emulates Classic 1K at the command level while supporting AES-128 internally. Use it when you need Classic compatibility today but plan to upgrade locks to AES mode within 1-3 years. It avoids buying Classic stock that will become obsolete after the lock upgrade."
    },
    {
      "question": "How much more does DESFire cost than Classic?",
      "answer": "At MOQ 10,000, DESFire EV3 cards typically cost $0.25-$0.45 per unit compared to $0.08-$0.12 for Classic 1K. The $0.15-$0.35 premium adds up at hotel volumes, but the cost is offset by stronger security, multi-application capability and longer platform relevance."
    },
    {
      "question": "Do I need a new encoder to switch from Classic to DESFire?",
      "answer": "Not always. Many modern desktop encoders from HID, Elatec and ACS support both Classic and DESFire via firmware update. However, some older serial-port encoders are Classic-only and require hardware replacement. Check with your lock vendor before ordering DESFire stock."
    },
    {
      "question": "What is the practical difference between DESFire EV2 and EV3 for hotels?",
      "answer": "All three (EV1, EV2, EV3) implement AES-128 and the file-system memory model. EV3 adds: Common Criteria EAL5+ certification (banking-card tier), transaction MAC for tamper detection, transaction timer for man-in-the-middle defense, proximity check for relay-attack defense, improved NFC Forum Type 4 implementation for Apple/Google Wallet provisioning, and slightly improved transaction speed (~10-15%) over EV2. For most hotel applications, EV2 is functionally sufficient — but properties planning Apple/Google Wallet keys, casino integration, or operating in jurisdictions with strict cardholder authentication rules should specify EV3 to avoid a re-spec later. Cost premium of EV3 over EV2 is typically $0.05-0.08/card at MOQ 10K."
    },
    {
      "question": "What is SUN (Secure Unique NFC) and why does it matter for hotels?",
      "answer": "SUN is a feature that lets the chip generate a unique cryptographic authentication code on every tap, verifiable by the back-end without storing the card key. For hotels this enables provable, per-tap audit trails for door openings — useful for liability disputes ('who entered Room 412 at 03:14?'), casino floor security, suite-level VIP audit, and forensic investigations after theft incidents. SUN is supported on DESFire EV3 (and on NTAG 424 DNA chips). It does not displace the AES authentication that opens the door; it adds a cryptographically signed event log per tap. For luxury, casino and conference properties this becomes a material differentiator. For limited-service properties it is overkill but does not add cost on the chip side."
    },
    {
      "question": "How do I detect if a 'MIFARE Classic' card is actually a Fudan FM11RF08/FM11RF08S clone?",
      "answer": "Three checks. (1) Tap the card with NFC TagInfo by NXP (free Android/iOS app). The 'Manufacturer' field should read 'NXP Semiconductors' for genuine Classic. Fudan clones identify as 'Fudan Microelectronics' or have anomalous ATQA values. (2) Check the SAK (Select Acknowledge) byte and ATQA pattern — Quarkslab and other security researchers have published clone-detection signatures publicly. (3) Demand the NXP authorized-distributor certificate of origin from the supplier; Fudan-sourced supply chains cannot produce this. The Fudan FM11RF08S backdoor compromises sector keys regardless of diversification, so any clone in your stock is a security risk that brand audits will flag."
