You're not paranoid if they actually are out to get you! Look at this article about RFID tags in new $20 bills. That's right, folks, the government IS actually tagging your money with electronic signatures! No longer is this the worry of the paranoid, but the worry of us all. According to the article, the right eye of Andrew Jackson in every bill was where the burning started. RFID technology is a unique chipping methodology that reacts to radio signals and transmits an identifying number when hit at the right frequency. Are these folks paranoid, or is this merely due to a smudge of metallic anti-counterfeiting in the bills? Looking at a $20 bill in my own pocket shows a rather strong smudge just above Andrew's right eye, but it looks way too small to be hiding a chip in there. I think it's more likely that what these folks have burned was a small metallic deposit used for anti-counterfeiting.
