I wish Apple (and Android) would build QR code/barcode scanning into all phones, either in the camera app or as a dedicated scanning app.

QR codes are so helpful for connecting the physical and digital worlds:  imagine scanning the bottom of a product to see the current owner’s manual, or to get reorder information.  Or scanning codes at a museum or park to get more information about an exhibit.  Or scanning the “missed delivery” door tag that FedEx left, to figure out your delivery options.

It’s not a new idea, but for the first time we’ve all got scanners in our pocket.  However, QR codes are still a little geeky:  you need to know what they are, and install an scanning app.  It’s a chicken-and-egg problem, and including scanning as a built-in phone feature would go a long way to seeding things.
