Amazon’s much-heralded convenience store of the future, Amazon Go, may seem like a crazy experiment. But the company plans to open as many as six more of these storefronts this year. Some of the new high-tech stores are likely to open in Amazon’s hometown of Seattle, where the first location is based, as well as Los Angeles. Amazon spent four years crafting a system — dubbed Just Walk Out Technology — that allows shoppers to scan their phone upon entrance, grab desired items off a shelf, and automatically get charged the right amount after exiting without the need to stop at a cash register to pay. Amazon is hoping that by making convenience store trips even faster, it will raise the bar for brick-and-mortar shopping in much the same way that Amazon Prime did for online shopping and delivery. If successful, the initiative would help Amazon become even more ingrained in the daily lives of consumers and grab a greater chunk of the giant food and beverage industry that still predominantly lives inside brick-and-mortar stores.
