Aisles

Wal-Mart is improving customer experience by allowing shoppers to scan and pay for items away from the checkout counter. With Apple’s new EasyPay feature as part of its iOS app, shoppers with an iPhone 4 or 4S can buy some products simply by scanning the barcode, entering their Apple ID, and walking out with the item.

Walgreens may be on the verge of revolutionizing the role of the pharmacist. The pharmacy operator is placing iPads in the hands of "health guides" across 20 pilot stores in Chicago.
