  "faq": [
    {
      "question": "Can UHF wristbands be used for cashless payment?",
      "answer": "UHF is not recommended for payment. The long read range means a reader could debit the wrong wristband, and UHF chips lack the strong encryption needed for financial transactions. Use HF/NFC chips for payment and combine with UHF on a dual-frequency wristband if you also need long-range tracking."
    },
    {
      "question": "What read range can I expect from a UHF wristband on a human wrist?",
      "answer": "Typically 2-5 meters with a standard fixed reader. This is significantly less than the 10+ meter range achievable with UHF tags on non-body-proximate applications because the human body absorbs UHF energy. Wristband-specific antenna designs with body-decoupling ground planes maximize range."
    },
    {
      "question": "Can UHF readers distinguish between multiple wristbands in the same area?",
      "answer": "Yes. UHF readers use anti-collision protocols (EPC Gen2 standard) that can identify 100+ tags per second. Each wristband's unique EPC code is read individually, even when dozens of wristbands are in the reader field simultaneously."
    },
    {
      "question": "Do UHF wristbands work in rainy conditions?",
      "answer": "Rain reduces UHF performance because water absorbs 900 MHz RF energy. Wet wristbands on wet skin may see read range reduced by 30-50 percent compared to dry conditions. Waterproof encapsulation protects the chip and antenna but does not prevent the RF absorption effect. Plan for reduced range in outdoor wet-weather events."
    },
    {
      "question": "Should I deploy UHF on a fabric, silicone or PVC wristband?",
      "answer": "Silicone is generally the best UHF wristband material because it can accommodate the thicker antenna stack and ground plane needed for body-decoupling without becoming uncomfortable. Fabric is possible but the rigid antenna module sewn into the band creates a noticeable bump. PVC works for short-duration applications where comfort is less critical. Tyvek is generally not recommended for UHF — the thin form factor cannot accommodate the antenna and ground plane needed for usable on-body read range."
    },
    {
      "question": "How does UHF wristband design differ from a standard UHF asset tag?",
      "answer": "Standard UHF asset tags are designed for free-space mounting on cardboard, plastic or pallet wrap — they assume no body or water nearby. Wristband-specific UHF designs add a thin metallic ground plane between the antenna and the skin to redirect radiation outward, plus thicker encapsulation to maintain antenna-to-skin spacing. Without this body-decoupling layer, a standard UHF inlay loses 50-80% of its read range when mounted against skin. Always source UHF wristbands from suppliers who publish on-body read range numbers, not just free-space numbers."
    },
    {
      "question": "Can UHF wristbands track attendees outside the venue (privacy concern)?",
      "answer": "Passive UHF wristbands can only be read by readers within 2-5 m on the wrist, so tracking outside the venue requires an attacker to install their own UHF reader infrastructure within that range. The privacy risk is real but bounded — it's not 'continuous global tracking.' Mitigations include (1) decommissioning the chip post-event by writing a kill code (UHF Gen2 supports this), (2) instructing attendees to remove the band at exit, (3) running the chip in a privacy mode that only responds to authenticated readers. GDPR / CCPA compliance is the binding requirement for any deployment with EU or California attendees."
