Zapped!/Preemptive Media mapped the results of their investigation about RFID use in Tokyo.

Preemptive Media are the guys who presented a video about the development of RFID technology, a display of “awareness” stickers and a cage of Madagascan giant hissing roaches at Thought Crimes: The Art of Subversion a few months ago. Preemptive Media attached reprogrammed RFID tags to the roaches that, if placed in a Wal-Mart store, will taint its RFID database. The group distributed the roaches at the show’s opening, sending them home with gallerygoers in Styrofoam coffee containers.

The idea is not to encourage paranioa, but rather participation and preparation!
