I'm a big fan of QR codes. A few years ago, I did some work for a major UK retailer who wanted to put QR codes on some of their DIY products. Rather than ship expensive instructions with each item, there would be a QR code on the packaging which linked directly to a video explaining how to use whatever it was you'd just purchased. The idea was a success and is now helping them cut costs - even in their after-sales service.
It's always nice when other companies imitate your success - and it's always amusing when they fall slightly short of the mark.
Lots of items in stores have QR codes on them. There's a limit to how much information you can cram onto packaging. It gives the customers more information, helps them buy the right product, and reduces the number of questions they ask a sales assistant. QR FTW?
If you look closely at the above package, you'll see a QR nestled in the corner. Sadly, the plastic around is is deforming it.
This, of course, renders the code completely unscanable.
