Virtual Grocery Shopping in the Subway
In an attempt to expand its market share in South Korean, the European grocery chain Tesco has come up with a brilliant idea. Tesco has launched a virtual grocery store in the subway. While waiting to commute, customers can purchase food items by scanning QR codes with their smartphones at virtual shelves installed right in the subway station. A delivery service drops off the ordered items at the customer’s door by the time they get home.
