Bidibooks in Spain have published the first two QR Coded city guides in their multilingual Urban Visions range. London and Paris will be followed shortly by New York, Rome, Barcelona and Berlin. A typical page includes photographs, locations and a QR Code. For example the page in the Spanish language version of the London Guide showing Camden Town Market has a QR Code that resolves to YouTube mobile Camden Town in Spanish.


I found a good website on QR code. You can generate barcodes, decode them with mobiles, etc. for free : http://www.jaxo-systems.com
