Amazon.com Inc. has developed a smart shopping cart that will ring up purchases and let consumers check out more speedily. Equipped with a flat screen, the Dash Cart will debut at a new kind of supermarket Amazon is opening later this year in the Woodland Hills neighborhood of Los Angeles, the company said Tuesday. The e-commerce giant has been trying to stand out in the competitive physical retail market, most notably with its Amazon Go convenience stores that automate the checkout process. Installing Amazon Go technology in existing stores would require shutting the location down for an extended period. By contrast, smart carts can be deployed without disrupting operations. It’s unclear if Amazon plans to license the Dash Cart to other retailers, but it already has competition: Caper and Veeve both sell carts that let shoppers scan products as they roam the aisles. Caper, for instance, is used in Ctown and Foodcellar in Long Island City, New York. source
