A QR code works in the same way as a barcode at the supermarket. A machine-scan able image instantly read using a Smartphone camera. Every QR code consists of a number of black squares and dots, which represent certain pieces of information. When your Smartphone scans this code, it translate that information into something that can be easily understand by humans.

QR codes can be read by any mobile phone with a camera, internet access and an application for reading QR codes. Some phones come with this application already installed, but for others, there are many applications available for free downloading online.
Usage is simple: when the application is activated, a screen similar to a camera will appear. Fit the QR code into the screen, photograph it and the application will automatically connect you to the web address or display the text contained in the code. One click and you are there!
