You Can Now Shop on Amazon by Taking Photos

Amazon.com's app for iPhone this week added "Flow," an image recognition tool designed to allow consumers to add a product to their shopping cart by merely pointing their phone's camera at it. Flow, as its name suggests, aims to make it as seamless as possible to shop. MarketWatch carried out its own "showrooming" with the app. Scanning a three-bottle package of the hair growth serum Rogaine, Flow immediately found the item on Amazon for $43.85, 30 percent cheaper than the $62.99 price in a Duane Reade store.
