The Chaos Communication Congress, held later this month in Berlin, will feature Open Attendee Meta-Data (OpenAMD) RFID badges that will track attendees' every movement, simulating life in the high-tech totalitarian state that many of the world's "free" nations are busy erecting.
Growing from the success of the OpenAMD Project at The Last HOPE in New York City this past summer, the CCC will be joining forces with SocioPatterns.org to add a real time proximity detection system so users can know what other users are nearby.
