For Korean commuters, going super market shopping is just another time consuming chore on their daily route. But what if things were made more fun by combining ambient marketing and mobile commerce? This is what Cheil Worldwide set out to do for Home Plus (what Tesco is known as in Korea).

An image that resembled a super market fridge was put up on a subway wall, with QR codes where prices normally go. Simply scan the QR code and products get added to your online cart. The best part of all? Your order will be delivered by the time you get home.

The results? A 130% increase in online sales between November 2010 and January 2011.

This project has won Grand Prix in Media, and Gold Lions for Direct and Outdoor.
