  "faq": [
    {
      "question": "Is Ultralight C secure enough for transit?",
      "answer": "Yes — Ultralight C runs 3DES mutual authentication (TDEA per NIST SP 800-67, 112-bit effective key), which has no published practical break. With per-card key diversification per NXP AN11136 the master key never leaves the issuer, so compromising one card reveals nothing about any other card in the batch. That is why Ultralight C is the default for disposable fare. When the credential is reusable or carries stored value, DESFire EV3 with AES-128 is the right answer instead."
    },
    {
      "question": "What is the difference between MIFARE Ultralight, Ultralight EV1, and Ultralight C?",
      "answer": "Ultralight (MF0ICU1, 64 bytes) and Ultralight EV1 (MF0ULx1, 48-128 bytes) use only a 32-bit password — brute-forceable, acceptable only for static NDEF records like a brochure URL. Ultralight C (MF0ICU2, 192 bytes) adds 3DES mutual authentication with a 112-bit key, making card cloning and replay significantly harder. For any programme with a security requirement — fare, access, ticket, pass — Ultralight C is the Ultralight-family choice."
    },
    {
      "question": "Can Ultralight C store monetary value?",
      "answer": "For low-value disposable use (single-ride fare, day pass, one-time loyalty claim) — yes. The 3DES-authenticated decrement counter and authenticated user pages support tear-off-style value tracking. For higher-value reusable stored-value (transit purses, campus cashless payment, loyalty wallets), DESFire EV3 with AES-128 and the on-chip transaction MAC is the right tier — its higher per-card cost is absorbed by the reusable lifecycle."
    },
    {
      "question": "Can a standard smartphone read Ultralight C cards?",
      "answer": "Yes — any NFC-enabled iPhone (XS or later) or modern Android reads public pages and NDEF records without authentication, because Ultralight C is ISO/IEC 14443-3 Type A + NFC Forum Type 2 Tag compliant. The 3DES authentication is used by the reader infrastructure — gates, terminals, turnstiles — to verify the card is genuine before reading authenticated pages. Consumers only tap; the cryptography stays in the reader."
    },
    {
      "question": "What MOQ and lead time should we plan around?",
      "answer": "MOQ 500 for blank white Ultralight C; 1,000 for custom-printed stock. Lead time is 10-15 business days for custom printed batches and 2-3 business days for blank stock from Proud Tek's factory inventory. Per-card key diversification, UID manifests, NDEF pre-encoding, thin 0.3 mm PET, and paper / Tyvek inlay variants are all available without MOQ uplift."
    },
    {
      "question": "Do you supply NXP chip-authenticity certificates with the order?",
      "answer": "Yes. Every Proud Tek Ultralight C batch ships with the NXP chip-authenticity certificate and a spot-check 3DES-authentication log confirming the feature is present and responding on every sampled card — specifically to address the documented failure mode where another supplier substituted non-authenticated Ultralight (no \"C\") into a bulk order."
