Tesco’s mission in South Korea has been to become the number one retailer without increasing the number of stores. In order to achieve this, the company implemented a virtual shop, making use of QR-codes. Shoppers can easily select, order and pay for their products while waiting for the metro. Displays on the platforms represent the virtual stores and are actually replacing the shop itself. Your groceries are delivered to your door, just after you arrive at home.
The concept works for Tesco in South Korea. It is an excellent example of how shopping habits change using modern technologies that integrate the online and offline worlds. See video below.
