During Computers in Libraries 2010 we used QR Codes as an easy way for attendees to grab the URL’s for the many bloggers at the conference. For some folks, this use of the two dimensional encoding squares was old hat, and for others it was their first time seeing this 16 year old technology in action.
After years of use in Asia, QR Codes use is increasing in the US as a direct result of widespread adoption of smart phones with bar code scanning capabilities like Android powered phones and the Apple iPhone. The simple codes we used are just the beginning of what QR Code technology can express. The code on the right provides a link to the website of one of the Bloggers@CIL2010 – if you don’t have a phone with a barcode scanner, you can use one of the free online decoders like this one from ZXing.
Mark Sprague has written a very comprehensive post outlining QR technology and its many extensions and uses. Some of the designer codes he showcases are very cool. There are even QR codes with embedded graphics or company logos. I’d like to also thank Paula Hane, one of the LibConf bloggers and News Bureau Chief at Information Today, Inc. for featuring Mark’s post on Facebook since that is where I first saw it.
