Here Come Smartphone Barcodes

The British bank’s Barclaycard division is testing out a Grab+Go app that will eliminate the need to wait in long lines at the store by turning the user’s smartphone camera into a barcode reader. This pocket checkout works by having the shopper scan each item being purchased and then checking out via the smartphone app.  Barclaycard believes the app will “work best in independent shops and smaller convenient stores – the kind of places customers dive in to for just a few items.”
