A source-backed Czech Security BSides electronic badge record: the official BSides Prague 2025 schedule page announced a PCB badge powered by multiple processors, and a first-hand organizer retrospective documents the first generation of electronic badges, attendee chips, challenge XP, interactive panels, and nickname display.
Lifecycle
The organizer retrospective says each attendee received a chip for event activities, challenges awarded experience points, and the chip software was reversible for hidden discoveries.
The retrospective says the badge started blinking after assembly and displayed the attendee nickname plus other visual material.
Interactive panels were used for CTF signup, answer submission, attendee Sched-profile display, nicknames, profile pictures, and XP points.
The official page describes the electronic badge as a PCB-based, modular artifact powered by multiple processors with two different systems integrated together.
Operational history
The Czechia record remains source-backed and image-free rather than copying all-rights-reserved blog photos, event-site media, or generated badge art.
The catalogue keeps the record useful without inventing part numbers, exact processors, firmware behavior, or board-source availability.
