Guinness wanted to provide you with relevant solution to interact with social media platforms like Facebook and Foursquare while enjoying a tasty pint of black gold, thus the Guinness QR Cup was born. When the pint glass is empty, the QR code is unreadable, and when it's filled with ordinary beer, the same results remain. But, fill the glass with Guinness and the black liquid completes the code, transforming your drink into both a delicious beverage and interactive social media experience.
