Microsoft TAG connects real life with digital world

http://www.microsoft.com/tag/

„Microsoft Tag connects real life with the digital world. Microsoft Tags are small, colorful codes that can be printed, stuck, or displayed just about anywhere. When you snap a Tag with the camera on your internet-enabled phone, additional information or experiences are automatically opened on your phone. There is no fumbling with URLs or texting short codes. Microsoft Tags can make product packages, posters, print-based ads, magazine articles, exhibit signage, billboards, storefronts, business card, or just about anything else, interactive.“
