QR Codes: What are QR Codes?

QR codes (Quick Response codes) are two dimensional codes that can be read by mobile devices that are equipped with a camera and a browser.  The device's camera can 'read' the code and perform numerous tasks including linking you to a website, displaying text, or displaying contact info, amongst other tasks.

To scan the code you need to have a QR code reader installed on your mobile device.  Some mobile devices will come with readers already installed otherwise there is a wide variety of code readers you can install yourself.  The video below describes QR codes and suggests some free mobile QR apps to read the codes.
