More great work from AlmapBBDO, Brazil for Antarctica Beer. During the Carnival in Rio de Janeiro, they developed a Beer Turnstile. The turnstile encouraged people to take the train rather that drink drive after the carnival, all people needed for a free train ride was an empty Antarctica beer can. Via optical reading, the can was scanned and the subway turnstile opened for free. They even donated the cans to a can recycling NGO.
