South Korean grocery chain Tesco connects with busy people through an innovative new concept, Home Plus that they launched in South Korea. They created billboards the subway stations that feature a range of products that customers can then select and scan using QR codes with their cell phones, only to have the selected groceries delivered later to their doorstep. The displays are set up just like aisles in any grocery store, so while you’re waiting for the train, you can get that pesky chore out of the way. I would love to see this expanded to other markets.
