Given that there are plans to implant very small permanent RFID tags in
just about everything, I've already given some thought to defeating them.
I don't much care to have everything I own become a tracking device once
I get it home. (I'm thinking 'Minority Report' here)
What I was thinking was if you took apart a disposeable camera, and put a
coil wrapped around an iron core where the film can used to be (possibly
with a diode).
Then put a larger cap in the film take-up space. Wire the cap up in place
of the existing one, and wire the coil to the flash output.
Instant mini-EMP device. I wonder how many gauss you'd need to actually
fry an RFID?
Anyone think this would work?

  I've heard the rhetoric on this idea, but I can't imagine it
  actualy ever being implemented. Think about how hard it would be to
  steal something - damage the RFID tag, throw it in the cart, walk
  out. WAY to easy.
