South Korean Tesco is reinventing how people shop for groceries online. Instead of logging onto a computer and staring at small thumbnails of foods to buy groceries, Tesco has Koreans use their smart phones to scan for barcodes off many groceries images that got pasted onto walls of various places (e.g., subway station); foods bought this way could arrive home in the same day, I think! Tesco uses the Home Plus brand to refer to its new grocery system. Do you like to see South Korean Tesco’s Home Plus system to be adopted by grocery stores within United States?
