The E-Sylum: Volume 7, Number 11, March 14, 2004, Article 20 FOLLOW-UP: EXPLODING TWENTIES Ronald S. Thompson writes: "The USA Today article on counterfeits and the article on exploding twenties may be related. If there really is an RFID tracking device in the new twenties it should make them easier to separate from the fakes and therefore result in more counterfeits being found. However, I microwaved one new twenty for 60 seconds without any burning." OK, so who else tried microwaving some cash after last week's story? Fess up... Joe Boling writes: "Regarding the web article on RFID tracers in banknotes, you will note when examining the illustrations with the article that they did NOT have the new notes - most of the notes are the 1996-2003 series, with only three or four being the 2004 series (and one of those did not react). Not wanting to find a conspirator in every wallet, I propose that it is the metallic components in the ink that are reacting to the microwaves. It has long been known that US notes include magnetic (or magnetizable) inks. Based on the pre-1996 $20 I have that shows starvation of one of the ink fountains, I don't believe the portrait includes the magnetic ink, but it surely comprises the most concentrated deposit of black ink on the entire note, and if there are metallic ingredients in it, the reaction to microwaves could be predicted to match that experienced by "Dave and Denise." As for the euro notes, I can't find the E50 note that I have lying around here someplace, so I can't examine it for an RFID in the security thread, but I'd rather expect to find that there is a joint in the thread, or some other feature of its visual and electronic properties that would react with microwaves, rather than an RFID device (which I suspect has not been miniaturized to that level yet - for instance, where is the battery?). " [Actually, I don't believe RFID tags require a power source of their own - they pick up energy from the radio waves emitted by the RFID reader. -Editor] Wayne Homren, Editor The Numismatic Bibliomania Society is a non-profit organization promoting numismatic literature.
