A QR (Quick Response) code is a two-dimensional barcode that is readable by smart phones. It allows you to encode over 4000 characters in a two dimensional barcode. QR codes may be used to display text to the user, to open a URL, contain a link to a Facebook page, contain discounts at your local grocery store or to compose text messages. They can be printed out and used for tagging any real-word object. See http://en.wikipedia.org/wiki/QR_Code for information on QR codes.
