    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]
