Guinness QR Code Glass
Developed by BBDO, New York, the new Guinness Pint glass brings Beer advertising to a new level.
Once visible and activated, the clever QR code checks you in to Foursquare, tweets about your pint and/or updates your Facebook status. “And in a nice branding twist, you have to use Guinness — or at least another very dark beer. If your beer is filled with an ordinary pilsner like Budweiser, you won’t be able to read the code.”
