What is a QR code?
(Definition coutresy of Wikipedia)
A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with camera, and smartphones. The code consists of black modules arranged in a square pattern 
on white background. The information encoded can be text, URL or other data. Common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994, the QR code is one of the most popular types of
two-dimensional barcodes. QR is the initialism of Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.
