Guinness Takes on the QR Code
Guinness has done it again. They have taken the QR code to new heights with their new glassware.
The concept is simple - if the glass is full of Guinness, then the QR code is readable. If it is empty, or if an amber beer is in the glass, then it is not readable.
Another clever way to use the QR code to leverage your brand, as scanning the code with your smartphone will tweet, update your Facebook or check you in with FourSquare....genius....
My quest is to find this glass - let me know if you find it!
