Amazon's cashierless store scheme is expected to expand to two other U.S. cities, according to recent reports.

Advertisements in search of Amazon Go store managers in both Chicago and San Francisco have recently appeared on Amazon's website, all but confirming suspicions that the stores are being planned for those locations.

In January, the first Amazon Go opened to the public in Seattle where customers using the Amazon Go smartphone app can swipe their phones upon entering the store. Once inside, the customer can shop for items while the Amazon system "follows" them with cameras and sensors tracking what they select. As soon as the customer finishes, they simply leave the store with their selections, which they are eventually charged for.

So far, it is unclear when and where construction for the new stores will take place or when the stores are expected to open.
