"The world's smallest and thinnest RFID tags were introduced yesterday by Hitachi. Tiny miracles of miniaturization, these RFID chips (Radio Frequency IDentification chips) measure just 0.05 x 0.05 millimeters. "

So small they can be made into powder. They would be very difficult to physically find and get rid of.

(I've left the topic heading more vague in case people have content related to other devices to add.)
