Living in densely populated areas where millions of people visit grocery stores a day can make grocery shopping very tiresome and painful. Luckily for the residents of South Korea, Tesco has created a virtual grocery store using machines at subway stations. Users simply have to scan the QR code of the product they desire and the groceries will be delivered to their home.
Although there are already plenty of online shopping alternatives that users may go through, the appeal of Tesco's system comes from the fact that it is located in subway stations, a place where residents often wait to get around town. These virtual grocery stores allow users to do some quick and easy shopping right before coming home, without having to worry about crowded lines or lugging a bunch of grocery bags along. Of course customers who prefer to pick out their groceries by hand will still be able to visit one of their many local stores.
