  "faq": [
    {
      "question": "Does an NFC ring work with iPhone and Android?",
      "answer": "Yes for reading: NTAG213 is an NFC Forum Type 2 tag, and both Android and iPhone (iPhone XS and newer) read it natively - iPhone background-tap opens the URL or profile payload. For door readers, compatibility depends on your reader's configuration, so send us the reader model before ordering."
    },
    {
      "question": "Is the ring waterproof?",
      "answer": "The epoxy seal is water-resistant for daily life - handwashing, rain, showers. It is not dive-rated. If your use case involves sustained submersion (swimming programs, pools), tell us and we will specify a suitable construction explicitly rather than overstate this one."
    },
    {
      "question": "How much data fits on the ring?",
      "answer": "144 bytes of usable NDEF memory - a URL, a vCard, a review-link payload or a short command. It is not a data vault; it is a trigger."
    },
    {
      "question": "What is the MOQ and can we get our logo engraved?",
      "answer": "MOQ 500 pieces across your size mix. Laser engraving of your logo is available, and we can pre-write the NDEF payload so the rings arrive tap-ready."
