  "faq": [
    {
      "question": "Is DESFire EV3 always the better choice for new projects?",
      "answer": "No. DESFire EV3 is the better choice when multi-application, per-file access control, or EAL5+ certification is required. For single-application credentials at volume (enterprise employee badges, single-operator transit), Plus EV2 is often the right pick because it delivers AES-grade security at roughly half the silicon cost. Match the chip to the application complexity and the volume tier, not to the bigger feature list."
    },
    {
      "question": "Can Plus EV2 and DESFire EV3 be mixed in the same reader fleet?",
      "answer": "Yes, with a reader that implements both command sets. Most access-control readers sold since 2020 (HID Signo, Assa Abloy Signo, SALTO XS4) support the superset. Transit readers often support both by design because the installed base always contains a mix. Confirm with your reader vendor that their firmware reads both AES-encrypted Plus SL3 and DESFire EV3 AuthenticateAES flows."
    },
    {
      "question": "What's the migration path from MIFARE Classic to Plus EV2 in practice?",
      "answer": "Three phases. Phase 1: reissue the card fleet as Plus EV2 cards personalized in SL1 mode — existing Classic readers see them as Classic-compatible and nothing changes operationally. Phase 2: upgrade reader firmware to support Plus SL3 AES authentication, deploy gradually across the reader estate. Phase 3: migrate cards from SL1 to SL3 at next encounter (often coincident with annual card reissue). NXP AN1305 is the canonical reference for this recipe."
    },
    {
      "question": "Does DESFire EV3 require a different reader from Plus EV2?",
      "answer": "Not necessarily. Both are ISO 14443-A Part 4 (T=CL) chips. A reader that speaks T=CL and implements DESFire's AuthenticateAES and file-access command set can read both. Readers that only support Classic-style sector authentication cannot read DESFire. These are increasingly rare in 2026, but legacy hotel-lock installations from pre-2015 are worth checking before specifying DESFire."
    },
    {
      "question": "What's the practical difference between DESFire EV3 2K, 4K, and 8K?",
      "answer": "Memory only. All three have identical command sets, crypto, and performance. Choose 2K for up to ~5 small applications (badge + cafeteria + printer), 4K for medium multi-application loads (badge + cafeteria + printer + parking + access-log cache), 8K for heavy multi-use credentials (full enterprise stack + government-ID overlay). Per-card cost roughly doubles from 2K to 8K, so right-size the memory; overspec pays nothing back."
    },
    {
      "question": "Are there counterfeit Plus EV2 or DESFire EV3 chips to watch for?",
      "answer": "Yes. Counterfeit reports are rarer than for Classic because the personalization chain typically runs through NXP-authorized distributors, but re-marked silicon has appeared in budget-sourced card stock. Verify Originality Signature on a statistical sample of each batch (both chips support it) and demand distributor chain-of-custody documentation from any supplier pricing significantly below the NXP list price. Proud Tek's Plus EV2 and DESFire EV3 inventory sources exclusively through NXP-authorized channels."
    },
    {
      "question": "Can I do NFC phone HCE (Host Card Emulation) for Plus EV2 or DESFire EV3?",
      "answer": "Yes on Android (Android 4.4+ with HCE); yes on iPhone (iOS 13+ with Core NFC reader mode; HCE-as-card-emulation is limited by Apple's wallet-only restriction). For corporate mobile-credential use cases the industry norm is to use NXP's Applet SDK or a third-party mobile-credential platform (HID Mobile Access, Allegion Engage, SALTO JustIN) rather than build HCE from scratch. These are DESFire-native and work on recent iOS and Android."
