This image is the QR image for this blog's URL created at
Active Print. QR images store a link in an image format. Reader Applications are available to enable devices to read the link within the image. I downloaded "Glass", created by HP labs in Bristol, from the Active Print site to my Nokia N70.
By printing the image in hard copy or to a screen, a mobile phone user can be taken straight to a www without the need to type it in.
A great idea with a world of applications... Thinking caps on.
