Amazon may be facing new competition from Microsoft on its cashierless, automated store technology, according to a new report from Reuters out this morning. The report claims Microsoft is in the process of developing its own systems for tracking what people place in their shopping carts, but doesn't offer the details of how Microsoft's technology operates, or how it may differ from others on the market. Presumably, it would be similar to existing systems, like Amazon's. The Amazon Go convenience stores utilize a complex network of sensors on shelves, cameras, and A.I. to track what people pick up and place in their bag. Other startups are working on their own machine vision-powered checkout systems, as well, like Standard Cognition, AiFi, and AVA Retail, for example.
