Makes me think of this idea I had: the receipt printer developers should just add a feature to allow printing of a QR code that contains all relevant information on the receipt in CSV format. Customers could choose whether they want one and be charged a small fee or if they're fine without. Unless there's some pressure through government regulation to implement this, it won't happen though ... because who's least interested in customers comparing prices and having transparency in their spendings? The retailers obviously.
