At family mart in China, some of the pastries are in bags with a QR code and a bar code. If it accidentally scans the QR code the self checkout (not in English) goes into a weird mode and I have to get help. So I just learned to cover the QR code for any packaging that had both it and a bar code on the same side.
Yeah. But this is a problem this can fix, in theory. Instead of having multiple codes you could just have one with the info for every piece of the chain that needs it.
