Fullsix Group has brought the Facebook “Like” button off of your computer screen and into the real world. In the UK, visitors at Diesel stores can now scan a QR code associated with a particular product, “Like” the product, and post it to their Facebook walls. This is another interesting development for the usage of QR codes in marketing. As Fullsix explains, Facebook “Like” buttons are clicked 3 billion times a day, so “why not [do it] in the real world?”  Check out the video below to see the campaign in action.
