How Amazon Thinks It Can Get You to Hit 'Buy' in 2 Seconds or Less (Using Augmented Reality)

Amazon's recently released mobile app came with a new feature that's meant to make you buy your entire shopping list with as few clicks as possible.

The new app for the iPhone (Amazon hasn't announced plans for any other devices yet) comes with an augmented-reality scanner. Dubbed Flow, it's the new iteration of a feature called "Snap It," which let users search for items—mostly things like books, video games and CDs—by taking a photo of them.
