12.1 Auto-Sync In Jan. 2015 this special feature was added. Choose this option on the Advanced tab if you are not sure if Internet connectivity will be fast and stable throughout the event. You need to have selected the On-Device service type when creating the service.
Scans from all devices are automatically uploaded (‘posted’) to a shared online database and the synced database is automatically downloaded to each device. The default setting for posting scans is every two (2) seconds. The default setting for downloading databases is every two (2) minutes.
Both processes are completed in the background so the person scanning tickets can keep scanning without interruption. If connectivity is completely lost, then the scans are queued and synced when connectivity is restored.
