They obviously turned on QR code scanning capability on their tills at some point recently(ish) - I can't recall when but I think it was around a year ago. They turned it on, even though their products use 1D barcodes... And now, whenever a consumer item has a QR code too, the till freaks out when it reads the wrong one! They absolutely could ignore the QR code but their dev managers must care so little that this obvious fix is skipped and their continue to annoy customers needlessly.

Today's products require much more information because the devs decided to use XML for their data. It worked fine on their test machines with emulated readers and a QR code can hold 1-2kB of text so what's the problem?

I hate it.
