The global retailer Tesco is the third largest retailer in the world measured by revenues and the second largest measured by profits but it is the first in the world to publish its QR Code campaign statistics in real time. In what can only be called a stroke of genius Tesco has QR Coded print ads (image below) for “Call of Duty – Black Ops” with the bit.ly url shortener so that anyone can see the campaign statistics (image below). The QR Code resolves via the biy.ly url to a page were the game can be preordered. See how the campaign is progressing here. Thanks to Tesco’s Nick Lansley for the heads-up.
