Offline Ticket Scanning: What Happens When Internet Connectivity Fails?

Offline ticket scanning keeps an entry operation moving when a device cannot reach the server, but it changes the reconciliation problem. A device can validate against the ticket data it already holds, queue the scan locally, and synchronise later. That data may be stale, and another gate may make a conflicting decision before either device reconnects.

Plan the failure mode

Before an event, test device registration, ticket-data freshness, queued scans, reconnect and replay, pending-sync visibility, battery, and supervisor handling. Decide how staff handle a ticket that was revoked after a device went offline and how two gates resolve the same ticket scanned during the gap.

Nox-Tickets includes offline scanning queues and delayed synchronisation in its private-alpha capability model. The venue, network, and device combination still needs a controlled pilot; offline support should not be presented as a universal guarantee.
