    {
      "question": "What is the difference between MIFARE Plus SE and MIFARE DESFire EV3?",
      "answer": "Plus SE is a drop-in Classic replacement. It keeps Classic's 16-sector memory layout and can operate on existing Classic readers in Security Level 1, then switches to AES-128 at Security Level 3 once readers are firmware-upgraded. DESFire EV3 is a new architecture. An AES-128 file system with up to 28 firewalled applications, ISO/IEC 7816-4 APDU commands and Common Criteria EAL5+ certification. Choose Plus SE when you have a large installed Classic reader base and need phased migration. Choose DESFire EV3 for new installations or when you need multi-application architecture and EAL5+ assurance."
    },
    {
      "question": "Do our existing Classic readers need hardware changes for Plus SE?",
      "answer": "For Plus SE in Security Level 1 (Classic-compatible mode), no reader change is needed — Plus SE cards are recognised as Classic cards. To enable Plus SE Security Level 3 (AES-128), your readers need a firmware update that understands the Plus SE AES command set. Most readers manufactured after 2012 from HID, SALTO, dormakaba and ASSA ABLOY support this firmware upgrade; confirm with the reader vendor against your exact reader part number and firmware version."
    },
    {
      "question": "Can we mix Classic 1K and Plus SE cards on the same reader estate during migration?",
      "answer": "Yes — that is the point of the Plus SE phased model. During migration, Classic 1K cards continue to work on all readers, Plus SE cards in Security Level 1 also work on all readers, and once individual readers are firmware-upgraded they accept Plus SE at Security Level 3. No user experiences an access gap and no dual-credential parallel estate is needed."
    },
    {
      "question": "What is the difference between Plus SE, Plus S and Plus X?",
      "answer": "All three are in the MIFARE Plus family and support the Security Level ladder. Plus SE is the entry-point Standard Edition, with the Classic-compatible 1 KB layout and the four-level security model. Plus S adds a proximity check (distance-bounding protocol) to defend against relay attacks. Plus X adds SL2 command multiplexing and can run DES / 3DES / AES on a mixed reader estate. For most Classic migrations, Plus SE is the right answer; specify Plus S when relay attacks are in the threat model and Plus X only for specific legacy reader mixes."
    },
    {
      "question": "Once a card is switched to Security Level 3, can it be reverted to Security Level 1?",
      "answer": "No. The Security Level transition is one-way (SL0 → SL1 → SL3). Once a Plus SE card is committed to Security Level 3, it cannot be downgraded. This is intentional — it prevents an attacker from coercing the card back into CRYPTO-1 mode. Plan the level switch for the reader-upgrade cycle, not earlier."
    },
    {
      "question": "What is the MOQ and lead time for MIFARE Plus SE cards?",
      "answer": "Blank white Plus SE cards: 200-piece minimum, lead time 5–7 business days from stock. Custom 4-colour printed Plus SE cards with overlay lamination and sector-key encoding: 500-piece minimum, 12–15 business days from artwork approval. Every order ships with migration planning documentation and sector-key configuration templates so the issuing team can line up the encoding workflow with the reader-upgrade plan."
    },
    {
      "question": "Does Plus SE support NFC tap-to-URL on a smartphone?",
      "answer": "No — Plus SE's memory layout is Classic-style sectors, not NDEF. iPhones and Android phones will read the UID but not the sector content without specific SDK code. For smartphone tap-to-URL workflows (marketing, authentication, DPP) pair Plus SE with an NTAG 424 DNA or DESFire EV3 SKU — both are NFC Forum Type 4 tags and open URLs natively. (For low-cost tap-to-URL without authentication, NTAG 213 / 215 / 216 are NFC Forum Type 2 tags that also work.)"
