Amazon unveils plans for grocery shop with no checkouts

Amazon has revealed plans for a shop where no checkout process is necessary. Customers will instead pay for the goods they have selected via an app. The Just Walk Out shopping experience uses the same types of technologies found in self-driving cars. The system detects when items are taken or returned to shelves and tracks them in a virtual shopping trolley. Once the shopper leaves the store, their Amazon account will be charged and receipt sent to them.
