McDonald’s has created a mobile coupon system that is used in an astounding 15% of all transactions in their stores in Japan. The site has 14 million users, and the coupon/payment application they developed has been downloaded 4 million times.

In this video we give a run through of the mobile site, then head out on the streets and film the mobile coupon app in action. Take a look!
