Just a quick introduction to QR Codes.
Firstly, you’ll need a smart phone!
Secondly, you’ll need to download an app that can translate the QR code into the link embedded within it.
For iPhone we recommend QRReader
For Android we recommend QR Droid
For Windows we recommend Scan
Once you have this installed on your phone, just open the app, point the camera at the image and you’re done!
