## FAQ
- Q: Does the blocking card affect my transit pass or building access card?
  A: Yes — the blocking card shields every 13.56 MHz card nearby, including transit passes, access badges and contactless payment cards. The usual deployment pattern is a two-slot wallet with the blocking card on one side and a single 'ready-to-tap' card on the opposite side; the user turns the wallet around to tap. Some users carry two blocking cards (one each side) and remove one when they need to tap. Phone-based payments (Apple Pay, Google Pay) are unaffected because the token lives on the phone, not in the wallet.
- Q: How do I know it is working?
  A: Active blocking cards with LED indicator windows light the LED during a detected reader burst. Passive blocking cards can be tested by trying to tap a protected card at a POS terminal or test reader while the blocking card is in the same slot — the transaction should fail; remove the blocking card and it should succeed. Our per-batch test report includes the 13.56 MHz attenuation curve measured on an ISO/IEC 10373-6 reference reader — attenuation of ~30 dB at 2–3 cm is the typical passive spec.
- Q: Is RFID skimming a real threat?
  A: It is a real physical capability but the practical threat varies by credential type. EMV contactless payment cards tokenise the PAN, cap single-tap amounts (EUR 50 / GBP 100 / USD 100 typical) and authenticate the merchant — UK Finance and FTC data show contactless payment fraud is rare relative to card-not-present and magstripe fraud. The more substantive threat sits on legacy access badges with static UIDs (MIFARE Classic, HID Prox, EM4100) and transit cards where UID enumeration links to a holder's movements, plus cross-border e-passport privacy. Position the product on those threat models rather than payment-fraud marketing copy.
- Q: What is the MOQ, lead time and packaging option?
  A: Passive blocking cards: MOQ 500, lead time 10–15 business days. Active blocking cards with coin-cell + LED: MOQ 1,000, lead time 15–20 business days. Packaging options from 500 units: blister pack with shelf-ready header, individual card sleeves, branded gift box, or multi-pack carton (3 / 5 / 10 cards) for travel-accessory retail. Per-batch 13.56 MHz attenuation test report (ISO/IEC 10373-6 reference reader) + ISO/IEC 10373-1 durability report + FTC advertising-substantiation data ship with every order.
