What is it.
A QR code is a two-dimensional code that depict data in a square that is made up of black and white dots. QR codes contain textual information or URLs that direct users to sites on the Internet. In order to read the information contained in a QR code, you will need two items: mobile camera phone and decoding software. Software applications are available as free downloads or for purchase.

How do I read a QR code?
You will need a mobile camera phone that has QR code reader software. You can download a free scanner by navigating to i-nigma.mobi on your mobile phone. Aim your cell phone camera toward the QR code and the program will scan the image. The software interprets the code and the cell phone will either display a text message or ask you to launch a specific web page.

How do you generate a QR code?
You will need a QR code generator which can be found free at the bottom of this page and other places online. Users enter in the data that needs to be translated and the generator creates the code. The code can be used in printed materials or presented electronically.
