RFID-Zapper

I ran across a neato technology today: a pocket EMF pulse gun, aka, the RFID-Zapper. Since it's been reported that the U.S. e-Passport technology standard has been demonstrated as insecure in the Netherlands, destroying your RFID in order to protect your identity may become important while you're overseas in a year or two.

Strangely, I can't find anything at the U.S. State Department which says for sure if a passport with a busted RFID tag is still valid for re-entry, though I expect that the human-based interview will get you across the border with only a little extra hassle.
