Tesco: Virtual stores
Tesco's Homeplus virtual stores in subway stations have been greatly successful and generated considerable buzz. Users simply scan QR codes with their phones, and the products land in an online shopping cart. When the purchase is complete the products will be delivered same-day. The concept taps a market of hardworking Koreans who have limited time to shop. This QR code project is not only creative, it's very useful, which is rare for QR codes.
