Day 70 - Virtual shopping (1)

It is already a while ago since Tesco opened a virtual supermarket on a subway platform in South Korea. Recently, they opened a larger version of this concept in Seoul. The concept is the same: pictures of products are posted on a wall, with QR codes underneath. Shoppers use their smartphones to scan the codes of the items they want to buy.  With 500 more or less 'familiar products in the store, this is a real time-saver.
