Lanyard reuse and donation workflow
The FAQ asks visitors to bring a reusable lanyard or donate lanyards so the event can reduce waste while still issuing wearable badges.

GPN23 Identity Badge
note
No local GPN23 identity-badge image is published because the public how-to, FAQ, awareness, and orga pages document the badge workflow but do not provide a rights-cleared original badge photo or official reusable raster render with complete attribution and processing provenance.
The record remains image-free rather than copying wiki images, badge-design screenshots, attendee photos, placeholder art, or generated approximations.
GPN23 Identity Badge
note
The public record supports a printed identity badge and lanyard workflow, not an electronic PCB badge for GPN23.
The dossier keeps GPN23 discoverable while preventing false firmware, microcontroller, app-store, or hardware claims.
GPN23 Identity Badge
note
The FAQ describes GPN23 as having no classic tickets while still requiring registration and noting that capacity exists.
Badge pickup and identity workflow should be read alongside the event's registration and capacity-control model.
