uQR.me is a free social utility that gives users the ability to share web content out in the real world via a QR (Strange pixelate squares that graphically reproduce a URL).
People can register to get a free personal QR and link it to any photo, video, webpage, Facebook page, Twitter, Flickr, a resume, a "For Sale" sign or anything they desire. uQR.me members have the freedom to print and post their QR anywhere, like a wall, a t-shirt, a wine bottle, a business card... literally anywhere. People who "spot" the QR with their cell phones are automatically directed to that persons or companies online content.
This online content could be a video related to what you're reading, it could be a contest powered by the brand advertised at a bus stop or detailed info about artwork at an exhibition. In short, QR codes link objects in the "real" world to the web, introducing a new dimension to everyday life.
