Hardwear.io documents leaving the badge's presentation mode around the 6:30 mark and uploading pictures afterward, turning the attendee object into a reusable e-paper display target.
Operational history
Issues & Camp Impact
No Hardwear.io Netherlands 2023 E-paper Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The Netherlands record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The badge was a reused e-paper price tag rather than a custom conference PCB.
The compendium treats it as a badge-hacking object and post-event firmware target while avoiding unsupported claims about custom hardware design.
Public details found in this pass describe the e-paper tag workflow but not a complete bill of materials, radio protocol teardown, or production team list.
Future work should add chip-level tag models, packet captures, firmware forks, and attendee writeups if they are published.
