Stick it to the man with your very own RFID-Zapper

Another Engadget curio. This one is oddly comforting to me: Stick it to the man with your very own RFID-Zapper:

it's fun to see some of the more paranoid types take matters into their own hands and kill those privacy invaders dead with the RFID-Zapper, a hacked up disposable camera that delivers an EMP of sorts to unsuspecting RFID tags, sending them to that great inventory management system in the sky.

It's nice to know that future fascist states won't be able to rely too much on RFID tags, not if we can bear arms like this to neutralize them. I wonder if the new RFID passports are designed with something like this in mind?
