  "faq": [
    {
      "question": "Is MIFARE Classic still safe for hotel key cards in 2026?",
      "answer": "For specific property profiles, yes. For others, no. Classic is acceptable at budget-tier properties where guest-key cloning has limited reputational and financial consequence, and where the reader fleet cannot support a newer chip without capital expenditure. Classic is NOT acceptable at luxury properties, corporate-hospitality flagships, or properties with compliance exposure (ISO 27001, government-guest programs). When in doubt, specify Plus EV2 — it reads on Classic-era readers via SL1 mode and upgrades cleanly to AES when the reader estate is ready."
    },
    {
      "question": "Does Plus EV2 require lock replacement in our existing property?",
      "answer": "Usually not. Plus EV2 in SL1 mode presents to legacy readers byte-for-byte as MIFARE Classic. An existing Saflok MT or Onity Advance reader reads Plus SL1 cards without firmware change. Confirm this with your lock vendor on your specific firmware version. There are edge cases on very old reader generations (pre-2008) where even SL1 doesn't work. For the vast majority of post-2010 installed bases, Plus EV2 is a drop-in card replacement."
    },
    {
      "question": "When is DESFire EV3 clearly the right chip over Plus EV2?",
      "answer": "Three cases. (1) Multi-application cards. The card needs to serve room access AND spa access AND F&B charging AND loyalty AND parking on one credential; DESFire's file-system model is the correct architecture. (2) Compliance requirement: the property's compliance framework mandates EAL5+ hardware; Plus EV2's EAL4+ is insufficient. (3) Greenfield or full lock replacement. When you're installing new locks anyway, DESFire is the future-proof choice. For drop-in migration from Classic without lock replacement, Plus EV2 is the pragmatic pick."
    },
    {
      "question": "Can we mix Classic, Plus, and DESFire cards across our portfolio?",
      "answer": "Yes, but plan the encoder infrastructure. The lock readers speak the union of chip types their firmware supports, so a reader that speaks DESFire also reads Plus and Classic. The issuance-side complexity is in the front-desk encoder: one encoder SKU that speaks all three chips is available from all major vendors, but legacy encoders from the 2010s may only speak Classic. Verify the encoder fleet's chip support before standardizing cross-property."
    },
    {
      "question": "How does the CRYPTO1 break affect our Classic-based properties?",
      "answer": "Practically, any attacker with €100 of hardware (Proxmark3) and physical access to a Classic card for ~30 seconds can clone it. The operational mitigation is re-encoding cards on every check-in and checkout. A cloned card expires with the guest stay. For properties where a guest-stay-scoped cloning window is acceptable (most hotels), Classic remains operational. For properties where the threat model extends to multi-night cloning (extended-stay, timeshare, high-value suites), specify Plus SL3 or DESFire EV3."
    },
    {
      "question": "Do NFC mobile wallets work with these hotel cards?",
      "answer": "Different question. NFC mobile credential for hotels (HID Mobile Access, Salto JustIN Mobile, Assa Abloy Mobile Access) is a separate credential-delivery mechanism that works alongside physical cards. The phone emulates a DESFire-family credential over HCE or BLE. None of the three physical card chips (Classic, Plus, DESFire) is 'replaced' by mobile; they coexist. Properties with mobile-credential as the primary guest path typically standardize on DESFire EV3 for their physical-card backup fleet because the readers already support DESFire for the mobile integration."
    },
    {
      "question": "What if our chain has 500 properties with mixed lock vendors. How do we standardize?",
      "answer": "Two practical patterns. (a) Standardize the card fleet on Plus EV2, standardize the lock-vendor spec for new builds on DESFire-capable hardware, and migrate the card fleet to DESFire EV3 over 7-10 years as property refurbishments converge the lock estate. (b) Segment the fleet. Luxury brands on DESFire EV3, mid-market on Plus EV2, economy on Classic. The second pattern reflects the reality of multi-brand portfolios; the first pattern is simpler operationally but costs more in the near term."
