Amazon is breaking into physical retail(零售) in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

    The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code. They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt(收据).

    The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e­commerce company would expand its dominance(主导地位) from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest(大胆的) bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

    However, the company could be thought of as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. And Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos, “He's using the Washington Post for power so that the politicians in Washington don't tax Amazon like they should be taxed.”

    “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in 2017.
