WHAT ARE QR CODES?
QR codes are two-dimensional barcodes that can be scanned by a mobile
device camera. The mobile device is then prompted to load a Web page or
display text or other data contained in the code. Although this technology is
now starting to catch on in the United States, it has been around for some
time now. The technology was created by Denso-Wave, a Japanese based
Toyota subsidiary, in 1994 as a way to track manufactured parts (http://
www.denso-wave.com/). Denso-Wave holds the patent rights to the QR
code technology but, instead of exercising those rights, decided to make
the technology freely available.
