Apple is planning to update its retail store iOS app so consumers can utilize self-checkout for purchases of accessories and other shelf-stocked items at the company’s retail stores, according to “MacRumors” (http://www.macrumors.com). The self-checkout purchases will be charged via the Apple Store app to the customer’s iTunes Store account, the article notes.

It is not entirely clear what will happen once a user has checked out via the app, although store employees will of course be on the lookout for store visitors walking out with merchandise in hand, as they are already. Customers who have made a purchase through self-checkout will be able to show an emailed receipt to any employee, confirming their purchase.
