Scanned items do not appear in the shopping cart
If the device scans but the desired items do not appear in the shopping basket, this indicates that the barcode scanner has not been correctly connected to the iPad or iPod via Bluetooth. In this case, try to reconnect the scanner.
Barcodescanner ist verbunden, aber scannt nicht
If the iPad / iPod keyboard no longer appears due to the use of the POS Hand Scanner or if items cannot be scanned correctly, it may be because the scanner is no longer in iOS mode. Follow the instructions here to put the barcode scanner back into iOS mode.
