Amazon is trialling its cashier-free store concept in larger locations than its existing Go stores, according to the Wall Street Journal.
This comes on the heels of a report in October, which claimed that Amazon was seeking to acquire UK retail sites as much as three times larger than its first Go store in Seattle.
Amazon Go outlets use computer-vision technology and a form of AI to monitor people entering the store. Their selections are also monitored as they walk around and they are automatically charged when they leave.
According to a source speaking to the WSJ, the technology functions well in a small space, but is more difficult to use in large sites with higher ceilings and more production.
Amazon is said to be considering using the technology in its Whole Foods supermarket chain, which specialises in selling organic food. There are almost 500 in the USA and UK, although the majority are in the USA. All seven of the UK stores are in London.
Amazon has built three Go stores in its hometown of Seattle and two in Chicago, with others planned in New York and San Francisco. Some reports claim that Amazon wants to open as many as 3,000 branches across the US by 2021.
A lengthy testing and evaluation process delayed the launch of Amazon's first Go store in Seattle, but it eventually opened in late 2016.
Since then Amazon has opened several new stores this year, as well as officially ending the beta period on its first location. It will need to speed up that rollout if it hopes to hit the 3,000-outlet target and compete with other cashier-less concepts like Zippin, however.
