Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
No historic HITCON PCB hardware, controller, firmware, game, connector, display, or BadUSB claim is carried forward into the narrower 2026 NFC attendee-badge record.
Evidence
HITCON's official events page says every attendee badge embeds an NTAG215 NFC chip and describes the phone-tap card-exchange activity. It does not publish tag configuration, payload format, application details, access-control behavior, privacy terms, security model, or a 2026 PCB/firmware specification.
HITCON's official conference page gives the planned August 21-22, 2026 dates and the Humanities and Social Sciences Building at Academia Sinica venue. It establishes event context, not badge construction, allocation, firmware, or image rights.
The organizer-linked KKTIX page identifies HITCON 2026 ticket-package conditions and explicitly names an attendee badge. It does not establish a complete all-tier allocation ledger, final physical form, credential behavior, or completed handoff.
Source trail
Primary organizer-linked ticketing source whose published package conditions name an attendee badge. It does not prove a final allocation ledger, all-ticket-tier eligibility, physical construction, or access-control role.
Primary official source for the planned August 21-22, 2026 conference at Academia Sinica. It supports event context only and does not provide attendee-badge technical specifications.
Primary official programme source stating that every attendee badge embeds an NTAG215 NFC chip and that a phone-to-badge tap exchange unlocks collectible cards. It does not disclose tag contents, application protocol, privacy/data processing, security design, or a 2026 PCB/firmware platform.
