QR Codes - Journey Continues
My personal journey on QR codes continues. Since ALD joined the Handheld Librarian IV virtual conference I logged in for the session "Libraries and QR codes". A lot of information was presented such as where they were originated from, history behind them, the benefits and challenges associated with using QR codes, how they could be used both in libraries and outside libraries, and a lot more. Did you know that conventional barcodes could hold 20 to 40 characters while QR codes could hold up to 7,089 characters? Did you know that conventional barcodes could store information only horizontally while QR codes could store information both vertically and horizontally? Did you know that in Canada they started to use dynamic QR codes for passport applications? These dynamic codes change instantly before your eyes while you typing your application. At Kentucky State University library they have already started to use QR codes. They are also considering using them for library directory and as a tool for Reader's Advisory - for example, scan the book's QR code and get attached information on similar books. I enjoyed the session very much.

QR codes are everywhere! Last night while watching a political debate on CNN they had a QR code on the screen and told the audience to take a picture of the code and it would give them more information about the candidates. I also noticed that they failed to tell the television audience that you needed to have a QR code reader!
