Why do people go to music festivals? The music of course! But we all know how much fun mingling can be, especially when beer is involved.
Heineken has used a QR code as the basis for a campaign to help music fans mingle at the Open’er Music Festival in Poland.
A station was created where festival goers could create a personalised QR code with a message attached as a means of breaking the ice. They called it the U-Code.
