It can recognize more than 100 million items, with consumers simply taking a picture of a book, DVD or other product to link back to Amazon’s store. The phone will also have audio recognition for movies and TV shows, which Amazon also carries. “I’m going to buy a whole lot more things with this technology than I ever have before,” said Ralph De La Vega, head of AT&T’s mobile business, at the event.
