Amazon is opening a second cashier-less Go store in Seattle this fall

Amazon is expanding its Go cashier-less supermarkets, with the company now confirming a second store coming to Seattle this fall, via a report from GeekWire.

The new location will continue the gradual roll out of Amazon’s experimental new retail stores, with locations also in the works for Chicago and San Francisco (although there’s no date yet on when those stores will be opening.) The new Seattle store is said to be almost twice as large as the current one, measuring in at 3,000 square feet, compared to the existing 1,800 square feet location.

The first Amazon Go location opened earlier this year, and has customers scan their phones when entering the store. Then, through the use of sensors and cameras, Amazon is able to automatically track what customers are purchasing and charge them accordingly, without ever needing to check out.
