What're QR codes?

Chances are, if you've been around Wallace Hall lately, you've seen the flyers I've posted about my Fall 2011 HNFE Librarian Office Hours:

I do this every semester.  However, this semester, you may notice a new image on that flyer--a QR (Quick Response) code.  You've probably noticed these little codes popping up in magazines, and all over the place.  Basically, they're used as a quick link from the physical world to the digital world.  You would use your mobile device (iPod Touch, iPhone, iPad, Blackberry, etc.) to scan the QR code, which would then act like a link to a webpage.  If you scanned the QR code on the flyer, it would take you directly to this blog!  

Basically, it's pretty easy to both generate and scan QR codes.  One of the better-known QR code generators is called Kaywa:  You can simply pop in a URL, and generate a code right there. 

Devices usually need a code reader in order to read these codes; some mobile devices come with QR code reader.  Others will require you to download one.  For my iPad2, for example, I needed to visit the app store and select a free QR code reader app.  You can find many lists (like this one) that will detail the pros and cons of various QR code readers.

If you'd really like to play around with QR codes, visit Newman Library to take our self-guided QR code tour!  Don't have a mobile device?  Check out an iPad2 from the circulation desk in order to take the tour!  Just let me know if you have any questions about that.
