What are they?, Think of QR codes as a virtual right mouse button, anything you want ‘more information about’ you just point and click with your mobile phone and then you'll be instantly directed to content such as audio, mobile sites, videos and more..

What can these codes be used for?

1. Quickly transport users from print materials to digital
2. Help users save information on their mobile devices for later use
3. Allow consumers to quickly take action or learn more
4. Create intrigue and a viral buzz for your cam­paign by providing something new and fresh
