A program that parses an arbitrary shelf label and then displays a large-print normalized representation (like the nutrition label) would be valuable.
The format of the URL is defined by the standard, so it can contain the EAN for the POS as well as additional data such as expiry date. Almost all 'barcode' scanners in use today can read QR codes so it just needs a software change on the POS.
The nutrition labels are pretty good (though sometimes the serving size is bogus — that should be normalized by the program). Also the unit cost (price per oz or whatever) is manipulated by the seller or mfr, and that should be usefully normalized too.
