Beer glass reveals scannable code when filled with Guinness
Posted on July 23, 2012 by molly
This is not an ordinary beer glass. It has Guinness QR code on the glass and only when it is filled up with Guinness beer will the code become readable. When you scan it with your smart phone, “it tweets about your pint, updates your facebook status…” With water and pale beer, the code is not scannable. Another example of creative marketing campaigns!
