INTERNATIONAL NEWS - In a move that could revolutionise the way we buy groceries, Amazon opens its first supermarket without checkouts - human or self-service - to shoppers on Monday.
Amazon Go, in Seattle, has been tested by staff for the past year.
It uses an array of ceiling-mounted cameras to identify each customer and track what items they select, eliminating the need for billing.
Purchases are billed to customers' credit cards when they leave the store.
Before entering, shoppers must scan the Amazon Go smartphone app. Sensors on the shelves add items to the bill as customers pick them up - and deletes any they put back.
