A major South Korean retailer owned by British giant Tesco has opened a virtual store in a busy Seoul subway station, for increasingly sophisticated smartphone users to order groceries and more.
Seven pillars and six platform screen doors have been plastered with images of life-size store shelves filled with goods — such as milk, apples, a bag of rice or school backpacks — which each carry a small barcode.
Shoppers download a related application on their smartphone and make purchases by taking photos of the barcodes.
