Holly sh... !!!  I think what we really need is a RFID Jammer ! I'm
not exactly thrilled by haveing any government agency (specially
a foreign one) being able to track my movements.
But than, aren't these things powered by the reader ? I guess
they would have to Emmit some sort of energy beam from low
orbit to activate a particular (or all) RFIDs in an area ...
Scary though ...
