QR codes and augmented reality

Over the last couple of days, some of the librarians on the ILI-L discussion list are wondering about the use of QR codes in libraries. Some say it hasn't caught on yet, so why bother? I think QR codes - or something similar - are bound to become more ubiquitous. QR codes are showing up everywhere. The "wait until later" attitude was enough to get me to sign up for the March 16 session at http://www.trendytopics.info/schedule.htm Lori Bell and Tom Peters are involved. That's an excellent endorsement - and ought to be enough of a cue to make sure you know about QR codes and augmented reality right now.
