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.
