## Description
A European multi-day music festival deployed 180,000 single-use UHF RFID wristbands across a four-day event for gate access control, age verification,...

## FAQ
- Q: Why not multi-use silicone bands?
  A: Single-use Tyvek is roughly 5× cheaper than silicone and the festival's procurement model treats wristbands as a per-attendee disposable rather than a multi-event credential. For a customer running a 12-event annual festival circuit, silicone wristbands can be reused at three or four events with the appropriate cleaning cycle, and the math flips. This case study customer chose Tyvek because the event is once-yearly and brand artwork changes annually.
- Q: How is cashless top-up handled on the wristband?
  A: The wristband EPC is the credential identifier; the cashless balance lives in the festival's back-office payment system, not on the chip. At the POS terminal the cashier scans the wristband (HF / NFC reader on a separate small surface area of the band, NTAG213 chip), the terminal looks up the balance over Wi-Fi, deducts the transaction, and shows the new balance. The UHF chip on the same band handles the gate-access read; the NFC chip handles the POS-payment read. The festival's POS partner is responsible for the offline-fallback flow when Wi-Fi drops.
- Q: What is the chip-clone resistance for a UCODE 9 wristband?
  A: UCODE 9 carries a unique 96-bit factory-programmed Serialized TID. A cloned chip would need both the matching EPC and the matching TID, and TID cloning requires factory-level silicon access. In this case study the gate-portal software does TID-vs-EPC cross-validation on every entry, which is how the 47 cloned-credential attempts were caught — they had matching barcodes from photographed legitimate bands, but no matching TID. Note: UCODE 9 does not implement on-chip AES-128 cryptographic authentication — that's a UCODE DNA (UHF) or NTAG 424 DNA (HF) feature. The clone-detection here is TID-based lookup, not cryptographic challenge-response.
- Q: What about read range when attendees are wearing the band under a sleeve or jacket?
  A: UHF reads through clothing without measurable degradation in the lane portal setup used here (Impinj R700 readers, 4× Times-7 A6034 antennas in a 1.8 m portal). Read range falls only when the band is pressed flat against a watch, phone or other metal-bodied wearable. Operations briefed attendees to wear the band on their non-watch wrist; less than 0.3% of entries needed a retry.
