09 Aug 2011, Shanghai, China — A passenger is scanning QR codes of the products on offer with a cellphone in a subway supermarket in Shanghai, China, 9 August 2011. A new mobile shopping experience is coming to major cities around China with a subway network, and is currently being tested in Shanghai and Beijing. Its basically a rip-off of what Tesco Homeplus has done in South Korea. Subway stations have been converted into virtual supermarkets. What you need to do is to scan the QR codes of the products you want, and once youre done with your purchase, the goods are delivered to your doorstep when you get home and are paid upon receipt. — Image by © Imaginechina/Corbis
