Wired's Quinn Norton reports today that Berlin's Chaos Communications Congress is allowing visitors (for a fee of 10 euros) to permit themselves to be tracked via RFID "CCC Sputnik" tags, which report their positions every few seconds to an array of 35 monitoring stations.

"The idea was that most of this surveillance technology slowly faded into our lives, and we accepted them," says project leader Milosch Meriac. "[We want to] make it possible to bring it into people's heads."

"The designs are part of a full surveillance suite that Meriac plans to release under GPL and Creative Commons licenses called OpenBeacon," Norton writes. "The suite includes not just transmitters, but receivers, a small configurable button, outputs for a piezoelectric speaker and the ability for tinkerers to reflash the firmware with other dedicated programs."
