Microsoft's retail ambitions are shaping up: American chain Kroger is testing its digital shelves and artificial intelligence in two stores. In addition, it wants to sell the technology to other retailers.

Microsoft is working on its own technology that should render checkouts in stores obsolete. The American company says it wants to be an ally for the retail sector, mostly in its struggle against Amazon Go.

Google's parent company Alphabet and Microsoft have failed to meet the first quarter expectations. Microsoft received the biggest blow, with a sizeable profit drop compared to the year before.
