A ticket is only worth what it protects. If a screenshot can get someone through the door, the person who actually paid is the one who loses. Today every ticket sold on TicketIt carries a cryptographically signed QR pass that can only be used once.
What a signed pass does
When a ticket is issued, we sign it with a key only our systems hold. At the gate, the scanner verifies that signature offline and marks the pass as used. A forwarded screenshot carries the same code — but the first scan wins, and every scan after it is rejected in real time.
- Single-use — once scanned, the pass is spent. No re-entry on the same code.
- Tamper-proof — edit a single pixel of the payload and verification fails.
- Offline-ready — scanners validate without a signal, then sync when they reconnect.
“We wanted the honest buyer to always beat the screenshot. Signing the pass makes that the default.”
— David Okoro
Nothing to turn on
This is live for every event, at no extra cost, with no setup. If you sell tickets on TicketIt, your gate is already protected. Fans keep their pass private until they are ready to enter, and organizers stop arguing with people holding duplicate codes.
