cashtab/src/components/Common/ScanQRCode.js
59 ↗	(On Diff #44453)	How does this work ? This branch will be executed if there is no error, but you will log an error, display an error and stop scanning. My guess is that the error is immediately hidden so you didn't notice.

cashtab/src/components/Common/ScanQRCode.js
69 ↗	(On Diff #44503)	handled also in testing I found another error to ignore. It's the 3 of 3 of subclasses of the ReaderException, so that should be all of them (the types of errors that come from the reader getting a bad scan of the barcode and thinking it is not a QR code, or has a bad checksum, or there is no qr code in the image ... in these cases we want to just keep scanning until we find a good qr code)
