Why It Mattered
It keeps a passive identifier artifact distinct from the active BLE tag at the same completed conference. The source supports a specific UHF/QR demonstration tag and a non-personal identifier claim, not a battery-powered badge, admission credential, attendee-tracking system, or a detailed technical implementation.
Hardware
The official source calls the artifact a custom-printed passive RAIN RFID/UHF tag with an associated QR code and a unique 96-bit identifier. It does not identify the inlay, integrated-circuit model, memory map, antenna design, substrate, dimensions, adhesive or lanyard format, print process, read range, QR payload, event-unit quantity, serial allocation, final artwork, test results, certification, production lot, or any active electronics. The record therefore remains a passive physical tag rather than a reconstructed electronic board.
Software & Apps
The source says the identifier is a custom conference/demo value, sequential, and not personal attendee information. It does not publish QR destination behavior, reader/backend software, data model, identifier assignment policy, scan logging, account linkage, authentication, access control, consent workflow, data retention, source code, software licence, or a deployed service. The record describes the published identifier framing without inferring analytics, tracking, entry permission, or participant-data practices.
Lore
The official badge page says Uniform Direct UK supplied passive UHF RFID labels for the twentieth-anniversary IEEE RFID conference and frames them as practical objects to compare and discuss. The event and its technical programme are confirmed as completed in Santa Fe, but the available sources do not state who accepted a tag, whether every attendee was offered one, whether the passive tag was issued with the active BLE tag, or whether it granted conference access.
official described identifier model
official badge documentation
The official page says each passive tag used a unique 96-bit custom conference/demo identifier, sequential rather than GS1 retail EPC, and not containing personal attendee information.
Compatibility: Source-described identifier model only; no source establishes identifier assignment, scan collection, backend records, owner linkage, QR destination behavior, access rights, or retention practices.
Source
official passive conference tag
official badge documentation
The official badge page identifies a custom-printed passive RAIN RFID/UHF tag associated with a QR code as the second conference artifact.
Compatibility: IEEE RFID 2026 passive badge as documented; the page does not identify the inlay, antenna, QR payload, physical dimensions, unit count, final artwork, or individual receipt.
