"wear" you going?

Well, looks like someone one-upped Admiral Poindexter. RFID (radio frequency identification) tags are miniscule microchips, which already have shrunk to half the size of a grain of sand. They listen for a radio query and respond by transmitting their unique ID code. Good if you want to nab shoplifters. Bad if they keep in radio contact after you've purchased something.
