TESCO store has opened the world’s first virtual shopping store in Seoul, Korea. All the Shelves are LCD Screens, and buyers choose their desired items by touching the LCD screen. At checkout after shopping, they have all their ordered stuff packed in bags waiting for them.
Also, for those who could not make it to the store, TESCO has pasted the virtual screens at subway stations. There, the buyers scan items of their choice with their smart phones, and the selected items are delivered to their homes upon their arrival.
