If your scanner is not scanning correctly, a useful troubleshooting step is to reset the scanner's configuration. Resetting the configuration of your scanner could prevent barcode scanning for your device, so preceded with caution.
1. Scan the Above QR code. (You may have to print this page if you cannot scan the screen)
2. Scan the barcodes in order (you might have to cover the other barcode with your hand), then tap Continue.
On rare occasions, some venues will need advanced configuration. Do NOT scan these bar codes and exit the screen by tapping Done. (If your business does need an advanced scanner configuration, contact our Help Center)
