Each ticket has a cryptographically signed QR, valid for a single check-in. Brighten your screen and have the code ready before you reach the door.
The organizer scans the QR in their door console. Used, expired, or forged codes are rejected.
If an organizer cancelled the event, do not travel — every booking is refunded in full automatically.
Organizers may deny entry where a ticket has already been used, is invalid, or was obtained against the Terms of Service.
