Offline scanning
Venue Wi-Fi and mobile signal can be unreliable at exactly the wrong moment. The scanner is built so a dropped connection never stops the queue at the door.
How it works
When you open an event in the scanner, it downloads a secure copy of that event's tickets to the device. The copy is stored locally and encrypted, so the scanner can validate a QR code even with no connection at all.
Any scans you make while offline are queued on the device. As soon as you're back online, the scanner:
- Syncs your queued scans up to Cleartix, automatically, about every 30 seconds.
- Pulls any new tickets down, so last-minute sales bought online still check in.
Load the event before doors open
Because the device needs to download the event's tickets first, open the event in the scanner while you still have a connection — ideally before doors open. Once it's loaded, you can keep scanning through patchy or absent Wi-Fi without interruption.
Note: While a device is offline, two devices can't see each other's scans yet. The same ticket scanned at two doors within the offline window may both show ✓ until they sync. Where this matters, keep at least one device online, or rely on a single gate per ticket.
