Online retailer Amazon has unveiled a new kind of store with no checkout lines. The store, which is located in Seattle, Washington – where Amazon is headquartered – sells “grocery essentials,” according to a video about the store posted by Amazon. Shoppers simply use the Amazon Go app, which the company claims can track items you want to purchase. Once you are done with your shopping, you simply walk out. Amazon says that by not having much of the staff of a normal store, it can keep prices low. Amazon Go will also allow the company to collect a treasure trove of data about shopping habits, both in real life and online. "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?" according to a statement on the Amazon Go website. Amazon Go is not the first foray into physical shops. The company experimented with brick and mortar book stores a year ago. But it may be a while before an Amazon store pops up near you. For now, the Seattle store is only open to Amazon employees, but plans to open to the public early in 2017.
