      "question": "Which chip should I specify for a festival cashless-payment wristband?",
      "answer": "The two industry defaults are MIFARE Ultralight C (3DES mutual authentication, 192 B user memory) and NTAG424 DNA (AES-128 SUN authentication, 416 B). Ultralight C is cheaper and is the long-standing choice for Coachella-class 3-day events. NTAG424 DNA is preferred where a SUN URL is read by phones at backup POS terminals, giving a tamper-resistant wristband that also works as a proof-of-purchase URL. Avoid MIFARE Classic 1K for any new cashless-payment deployment. CRYPTO-1 is broken and the wristband can be cloned in seconds."
    },
    {
      "question": "Are RFID wristbands waterproof?",
      "answer": "Silicone, PVC and vinyl wristbands are all IP67 or IP68 — fully submersible for 30 minutes at 1 metre depth. Silicone adjustable wristbands with snap-button closures are the dominant choice for waterpark and pool applications. Tyvek paper wristbands are splash-proof but degrade in sustained rain; woven fabric wristbands are splash-proof but should not be submerged. Reusable silicone wristbands that go through commercial laundry (uniform pools, hospital reprocessing) require IP69K with sonic-welded seams."
    },
    {
      "question": "How long does an RFID wristband last?",
      "answer": "The chip and antenna are rated for 100,000+ EEPROM writes and 10+ years of retention. Field lifetime is driven by the band material. Tyvek and paper wristbands last a single event (1-5 days). Vinyl and PVC strip bands last 1-7 days. Silicone adjustable bands last 2-5 years with normal wear; sonic-welded silicone (prison, long-stay hospital) lasts for the duration of the detention or admission. Woven fabric bands last 6 months to 2 years depending on closure and use."
    },
    {
      "question": "Can hospital wristbands carry both RFID and printed patient data?",
      "answer": "Yes: that is the standard configuration. A hospital patient-ID wristband is a soft PVC or medical-grade silicone strap with an RFID (NTAG213/216 or MIFARE Ultralight EV1) inlay laminated inside plus a thermal-print area on the outside where the admissions printer prints the patient name, medical record number, date of birth and barcode. This satisfies Joint Commission National Patient Safety Goal 01.01.01 which requires two patient identifiers (name and medical record number) printed on the band, while the RFID enables hands-free lookup, specimen labelling and medication scanning at the bedside."
    },
    {
      "question": "What is the read range of an RFID wristband?",
      "answer": "HF 13.56 MHz wristbands (NTAG213, MIFARE Ultralight, MIFARE Classic 1K, MIFARE DESFire EV3) read 0-6 cm from a proximity reader at the bar, gate or bedside. UHF 860-960 MHz wristbands with a body-tuned PIFA antenna read 1-4 m at a race-timing mat and 2-4 m at a waterpark gate. The free-space UHF range of 3-8 m drops to 50-70% when the band is worn against the wrist due to body-water absorption; specify an on-body UHF inlay (not a standard apparel UHF inlay) for any wrist-worn UHF application."
    },
    {
      "question": "Can RFID wristbands be reused across events?",
      "answer": "Yes, but only silicone, woven fabric and elastic wristbands with adjustable closures. A re-issued wristband is collected at the gate, industrially cleaned or wiped, and re-programmed with a new EPC, UID or AES-128 key set at the next event. Tyvek, PVC strip and paper wristbands with one-time adhesive clips are designed for single use. The clip breaks when cut, preventing resale. Large event operators (Live Nation, AEG) run reusable silicone programmes at corporate and VIP tiers while issuing one-time Tyvek or woven fabric at general admission."
    },
    {
      "question": "Do RFID wristbands work through a gloved hand or a pocket?",
      "answer": "Yes for HF — 13.56 MHz signals pass through textile, leather, latex gloves and thin plastic without attenuation, so a wristband under a long sleeve still taps reliably. UHF 860-960 MHz signals pass through textile and leather but are strongly absorbed by water and human tissue. An RFID wristband hidden behind the wrist (reader on the wrist-bone side, band on the radial-artery side) reads at roughly 30% of its worn-side range. Readers should be positioned so the wearer presents the wristband on the side where the inlay sits."
    },
    {
      "question": "Is cashless payment on an RFID wristband PCI-compliant?",
      "answer": "Closed-loop cashless wallets (festival top-up, cruise on-board accounts, resort all-inclusive) keep card data out of the wristband. The wristband carries only a unique UID that looks up a balance in the event operator's backend, so the card data entered at the top-up kiosk is processed under normal PCI-DSS v4.0 scope and the wristband itself is out of scope. Open-loop EMV Contactless integration (wristband-as-payment-card) is possible with certified EMVCo vendors and requires a specific wristband chip (SIM-based or secure-element) plus full merchant acquiring integration. This is usually out of scope for a standard wristband project."
