Using a Square iPad Stand terminal for retail, the rear camera is inaccessible. The iOS app for Memento Database only uses the rear camera for scanning barcodes, rendering this feature inaccessible since hardware barcode scanners do not work on iOS for this feature.

If there was either a setting or a toggle on the view fir switching to the front camera so barcodes could be scanned in this situation, this feature would become accessible again.
