I was watching an episode of CSI: NY and learned something new. One of the clues to solve a crime was a partial "qr code". They showed how to use a qr code enabled cell phone to unscramble the code. The code is linked to a specific website. Ok, maybe I am not explaining this well.

I also found this definition....A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes.
