Offline scanning uses attendee data downloaded to the staff device. Prepare each device while it has an internet connection.

​
Before losing connectivity

  1. Sign in to the mobile app and select the correct site and event.
  2. Open the event’s attendee list and choose Download for offline scanning.
  3. Wait for the download to finish successfully. If it reports Download incomplete, reconnect and try again.
  4. Refresh the download close to the event so recent sales and cancellations are included.
  5. Check each scanning device separately; a download on one device does not prepare the others.

​
Scan and reconnect

Use the normal mobile check-in flow. While disconnected, the app displays Offline — downloaded tickets only. It cannot rely on purchases or changes that arrived after the download. When connectivity returns, allow queued check-ins to synchronize. Review any failures or conflicts and confirm the attendee’s final check-in record before treating the reconciliation as complete. Two offline devices cannot immediately share a new scan with one another. Plan separate entry lines or ticket allocations when duplicate-entry prevention across disconnected devices matters. Handle an unknown ticket with an online staff device rather than assuming it is valid because its QR code can be read. Keep membership admission and other live eligibility decisions online unless the app explicitly confirms it can validate that record offline.

​
Confirm synchronization and resolve failures

Wait for Attendees saved on this device for offline scans before leaving connectivity. While offline, the banner reports scans saved locally. Reconnect with the app open or choose Sync; if the session expired, sign back into the same account. Saved scans survive an app restart. Use Review for rejected uploads and read the reason before changing the attendee’s status. Failed uploads remain available for retry or review. Do not clear the app’s data while uploads are pending. Offline mode currently supports one admission per attendee. Re-entry and tickets with check-in time restrictions require an online connection.

​
Keep checkpoint redemption online

For the checkpoint release, downloaded checkpoint tickets and accounts assigned to checkpoints cannot redeem entitlements offline. Reconnect before scanning; the scanner must check the current assignment and once-only redemption records. See Ticket checkpoints for the release prerequisites.
