Making these useful is what will help adoption. Right now, they're only being used for marketing purposes. I really like coffee, but I'm not so passionate about it that I will take out my phone, perform seven taps, and watch a bad marketing video about it. One can imagine useful scenarios though. A microwave which scans the QR and sets the desired cooking time. A little magnet on your fridge which, when you hold up a product to it (empty milk carton) adds that product to the shopping list on your smartphone. Things like this could be useful to the end-user and to marketers.
