This badass looking weapon won’t hurt a fly – but it will kill any RFID tag you point it at. The Rfiddler gun can be aimed at unsuspecting RFID tags and destroy their data by simply overloading the tags with a very strong electromagnetic field.
Codeninja built this device using a Nerf N-Strike Recon CS-6 loaded up with a 0.6 kilojoule camera flash driving a 50-turn copper spool. Now I have no idea how that works, but it sure sounds nasty. Also under the hood is an MP3 player with a 2-watt amplifier and speaker to crank out some good destructo sounds when the RFID eraser is engaged. As an added bonus, the Rfiddler momentarily blinds those who stand in front of it with a bright flash.
Apparently, it’s also strong enough to kill many USB flash drives. Given the way this thing works, I wouldn’t aim it at your credit cards, hard drives (or the cat) either.
