Aurasma - Augmented reality that might replace QR codes?
After becoming very popular in Asia and Europe, QR codes are just beginning to gain popularity in North America (for more on QR codes click HERE). However a new technology that recognizes images captured by a smart phone or tablet device can do many of the things QR codes can do - without the QR code itself. In this report by the BBC note how the Aurasma technology brings printed materials to life.

Of course walking around holding out your smart phone as demonstrated in the video may not be a smart idea in some cities.
