I think you are right in what you are saying but that means that QR codes would have to be widely adopted to make them native to the device you are looking at them on. And as the other commenter noted, what if the device dies? Airlines have been using QR style codes for years for bags etc so they can probably find a use for them. I'm all for advancements in technology but I somehow feel that this is a fad that will pass quite quickly unless they find an actual use for it
