Inside the Amazon Go store in Seattle.

Amazon is opening additional Amazon Go locations in Chicago and San Francisco as the company expands its cashier-less grocery store concept across the nation.

The Seattle Times spotted job postings for store managers in each city. That followed earlier reports from The San Francisco Chronicle and Curbed Chicago about building permits for Amazon Go locations.

An Amazon spokesperson confirmed with GeekWire that the company is opening Amazon Go locations in Chicago and San Francisco, but did not provide a timetable.

Hands-on with Amazon Go: We tested the tech giant’s experiment in checkout-free retail

Amazon debuted its first Amazon Go location at its headquarters in Seattle in December 2016; it opened to the public in January of this year.

Amazon Go is the online retail pioneer’s attempt to reinvent the physical store with the same mindset that brought one-click shopping to the internet. Any person with an Amazon account and the Amazon Go app can simply grab anything they want and walk out, without going through a checkout line.

After shoppers check in by scanning their unique QR code, overhead cameras work with weight sensors in the shelves to precisely track which items they pick up and take with them. When they leave, they just leave. Amazon Go’s systems automatically debit their accounts for the items they take, sending the receipt to the app.

Recode reported earlier this year that Amazon plans to open as many as six additional Amazon Go stores beyond the original Seattle location.

Amazon Go is part of a broader push by Amazon into physical retail, including its acquisition of Whole Foods, its Amazon Books stores, and AmazonFresh Pickup locations.
