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.
