To prevent duplicate orders, theby design does not allow a check to be accessed by more than one at the same time. Additionally, as a cloud-based Point of Sale system, are constantly syncing their check data to the cloud and with each other via the Internet. Attempting to open a check on Terminal B that is already open on Terminal A will yield an "Unable to Access Check" error message.
This constant syncing is maintained while the app is open and running on all. If the app is exited (or "backgrounded") on even a single , or if an iPad goes to sleep, the stops running on that , and syncing to all devices is disrupted. For this reason, we strongly recommend that all operators leverage to ensure the app stays open and running at all times.
“Unable to Access Check” Message
The check being accessed is currently in use on another. Please attempt access again when the check is no longer in use.
If abecomes inoperable (e.g. thrown down a flight of stairs, knocked into a sink, etc.) checks that were in use and/or syncing at that time may become inaccessible on other . In these extreme scenarios, can be used to Force or Override checks from the compromised device. Once is used, a check will never again be accessible on the from which it was recovered.
pulls the last complete version of a given check from the cloud and overwrites any data that was not fully synced to prevent data corruption from a damaged device. This can (and often does) result in some data loss, as the recovered version of the check is not always 100% up to date. Lost data typically includes and that appear to "fall off" the check.
Any data lost during this process cannot be recovered. For this reason,should only be used as a last resort method of recovering check information when a device becomes completely inoperable and checks cannot otherwise be accessed.
A Check is “Locked” on the POS
A check will appear Locked on theand when it has been recovered (Overridden or “Forced”) from a given . is intended for use when a device has been physically corrupted, and the software prevents the from which a check was Overridden from ever accessing that specific check again.
All other terminals will be able to access the check except for the terminal from which it was overridden.
"Check #### is no longer accessible on this Terminal" Error Message
The check being accessed has been recovered (Overridden or “Forced”) from theat which access is being attempted. The from which a check was recovered will never again be able to access the recovered Check.
