Britain Amazon Contactless Shop

The Amazon Fresh grocery store opens to the public in London, Thursday March 4, 2021, where shoppers will be able to pick up items and walk out of the store, contactless, without the need for a till. Customers will scan a QR code on their way into the store, with cameras and technology identifying the items that shoppers take from the shelves and their account automatically paid.
