Multiple readers have written to let us know that an experiment at the upcoming Hackers on Planet Earth (HOPE
) conference will use RFID to track the movements of at least 1,500 registrants
for the duration of the conference. Those movements will be transmitted onto screens which "show in real-time where people go, with whom they associate, for how long and how often." The system will also be used for games which involve manipulation of the available data. Meanwhile, researchers at the Georgia Institute of Technology have developed a method for testing large quantities of RFID tags
, which may serve to greatly speed distribution.
