Amazon announced on Monday that it will start selling payment technology without used box officials at Amazon Go stores to other retailers.

Just Walk Out technology allows shoppers to shop without having to queue to pay the box, as cameras and other sensors through the store monitor the goods that shoppers take and deduct their money when they leave automatically from their Amazon account.

Amazon has already signed several contracts with retailers interested in providing this technology with their stores, according to Reuters. It is not clear who are the companies planning to use this technology or the value of these contracts.

It will take a few weeks for Amazon to install digital technology in retail stores, depending on whether it is to be operated in a new or existing store, Amazon said. On current stores, Amazon said it would "work with the retailer to install technology while minimizing the impact on current operations."

Unlike Amazon Go stores, where users pass the Go app on a point to a revolving door when they enter, shoppers pass their credit card on a point to a revolving door in a store using the "Just Walk Out" technology.

Amazon said if shoppers need a receipt, they can visit a designated office in the store to enter their email address, and the receipt will be sent automatically to their email address the next time they visit any store and use the technology.

The move comes as Amazon continues to build its network of 25 Goo stores across America. Last month, it launched its first full-fledged supermarket (supermarket) without cash called "Go Groseri" near its headquarters in Seattle. Amazon is considering providing this technology at airports and cinemas.

In the company's 2018 message to shareholders, Amazon spoke of the growing importance of Go stores, where CEO Jeff Bezos said it was the biggest example of Amazon's efforts to "delight" customers, and described payment queues as "the worst thing in physical retail."

This marketing risk comes at a time when the world is witnessing a state of panic because of the rapid spread of the Corona virus around the world, as the use of cash and grouping of shops is one of the most common factors for its spread.
