Self Checkout the Apple way | New Apple Store App Launches
According to BI, Apple has introduced its own self check out that is facilitated by an iPhone app.
The app allows you to make orders from your iPhone 4 or 4S and pick them up in store within an hour. You can also make purchases within the store just by scanning an item’s barcode and paying within the app. There’s no need to interact with an Apple Store rep if you don’t want to.
Download the app at the itunes store
