ATtiny402 UFO PCB badge with source-described activity material
An electronic PCB badge identified by Punk Security's public source archive as the UFO badge for BSides Cheltenham 2024. Its repository preserves EAGLE, Gerber, Arduino firmware, vector-art, 3D-case, and activity-booklet material, and names an ATtiny402, button, CR2032 clip, and 5050 NeoPixel. The archive says the activity booklet was given out on the day. Punk Security's historical event timeline separately says it was the badge sponsor and had UFO badges, but currently renders that entry with an inconsistent early-2023 timestamp; the record therefore uses the repository's explicit 2024 badge identity without inventing an exact date or venue. The reviewed sources do not establish organizer-side 2024 confirmation, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, activity participation or outcome, safety validation, or reusable image provenance.

Flutter & Friends' organizer-published conference-app source added a Friends Badge editor on August 30, 2025: users could select an image, preview it with dithering, and write it to the conference badge through NFC. The companion `friends_badge` package explicitly describes control of the Flutter & Friends e-paper conference badge, and its implemented target profile is a passive four-color e-paper device. The source-backed record establishes a real event-linked electronic artifact at the completed Stockholm conference, but does not establish that every attendee received one, that it served as admission, or what final physical units contained.
Swiss ESP blinking attendee badge with SAO invitation
A source-backed Area41 2026 attendee electronic-badge record. The official event page said each attendee would receive an ESP-based blinking electronic badge and invited badge owners to bring Shitty Add-Ons (SAOs). The organizer's post-event recap identifies Technische Fachschule Bern as the badge designer and assembler, while the school's own update says it developed and manufactured the hardware; the recap also reports attendees soldered more than 300 SAO badge extensions.

Planned app-issued venue-access identity artifact
Barcelona Cybersecurity Congress 2026's official app page tells visitors to download the official app and secure a digital badge, calling it the essential key for venue access. The same page says the app will be available in September 2026, before the November 3-5 Barcelona event. This record models a planned app-issued access identity artifact only; it does not infer a physical badge, a PCB, a ticket entitlement, an account or credential format, or a final access workflow.
Planned printable networking identity artifact
Barcelona Cybersecurity Congress 2026's official app page says that, with the event digital badge, visitors can print a Networking Badge to facilitate connections with fellow attendees. It names the registration desk and the Hall 2.1 info point as print locations. This record captures that planned printable networking artifact without assuming its physical medium, design, personal-data fields, access rights, or relationship to the separate digital venue-access badge.
Planned student-pass conference identity artifact
Black Hat Europe's official 2026 registration and pass-comparison pages say Student Pass badge pickup is Thursday, December 10 only.

SemiTO-V Developer Zone RP2350/GW1N-9 electronic badge project
SemiTO-V's RISC-V FPGA Badge was a limited Developer Zone electronic PCB badge project for RISC-V Summit Europe 2026 in Bologna. Primary team sources name an RP2350 MCU, a GOWIN GW1N-9 FPGA, custom firmware, and a default RV32I core; they say NextPCB produced the boards and planned to bring 25 to the developer workshop. A logistics update then delayed intended June 8 distribution. The source record supports real physical boards and a 2026 event association, not a final unit count, completed recipient delivery, or the precise current post-event design revision.
Spanish ESP32 PACMAN CTF badge with project-builder and community-reversal evidence
RootedCON 2026's PACMAN-themed attendee CTF badge is documented by both community reversals and a first-hand TechFrontiers project-builder write-up. David Melendez Cano reports original colored Ghost boards that attendees could choose, an ESP32-WROOM-32 platform, ESP-NOW game-server interaction, per-badge NVS identity/key material, and digitally signed questions and answers. Community reversals independently identify an ESP32-D0WD-V3, 1.77-inch ST7735 128x160 display, directional controls, and native quiz-server CTF protocol for the March 5-7 sixteenth edition at Kinepolis Madrid.

Maker-documented ESP CTF challenge badge
A public maker archive explicitly titled Women's International Cybersecurity Challenge Badge 2026 links itself to WICC and documents a hackable serial-CLI CTF badge with ESP8266 and ESP32 target trees, challenge activities, a two-part protective case, and a repository photo of a physical cased device. WICC's official site and Cyber Ireland's post-event recap confirm the completed July 9-10 Dublin competition, but neither organizer source names this exact project. TOG separately reports building 15 ESP8266 hardware flags for the same CTF without identifying them as this archive, so this is a maker-documented event-linked electronic badge—not an organizer-issued credential, general attendee badge, or claim of equivalence to the flags.
Madrid Hackplayers electronic development-board CTF badge
A source-backed Spanish hacker-conference electronic badge record: the official h-c0n post says Hackplayers finally produced an electronic badge for the sixth 2026 edition, describes it as a fully functional development board, and ties pickup to the February 6 conference registration and CTF start; the public `therealdreg/hcon2026hwctf` repository and Hackplayers post-event write-up document RP2350/RISC-V firmware, tooling, named co-creators, and winner write-ups.

leHACK's official 2026 workshop schedule and the French National Cybersecurity Agency's leHACK listing present Badge Hackropole as a novice-accessible workshop in which participants assemble a capacitive light-up badge, solder a microcontroller and eight SMD LEDs, and program preconfigured WLED firmware. FCSC-FR's public hackropole-badge repository supplies the PCB source, assembly instructions, firmware binaries/configuration, and per-file licensing. The programme lists ten 55-minute workshop sessions across June 26-27, but the source trail does not prove final attendance, completed builds, or a conference-wide handout.
Polish conference-floor identity badge
A conservative x33fcon 2026 identity-artifact record: the official conference page documents the June 11-12, 2026 Gdynia edition and currently says registration is closed at full capacity, while the terms require all people on the conference floor to have a visible badge at all times. The official afterparty instructions separately tell attendees to bring a physical x33fcon ID or ticket to enter either venue.
