Using QR Codes to play a video as a moving overlay on a larger image is not a new idea, for example Victor Petit’s CV, Reporters Without Borders and Valiant Comics to name but a few. However using static images as an overlay never seemed a useful ecommerce option, until now. Tchibo is one of Germany’s biggest shop chains and they are advertising watches with a QR Code (image below). Scanning the code takes you to a mobile site where the watches can be ‘tried on’ by holding your mobile over your wrist. If you like what you see you can put the watch in a shopping cart and purchase it right away.
