Rfiddler – A SciFi-Gun that destroys RFID
Really funny video, shows Rfiddler devices in action, destroying RFID.
Codeninja developed this gadget that emmits a strong electromagnetic field which destroys sensitive electronics in RFID chips and some electronic devices (like usb-sticks).
All you need is to buy a plastic gun, some leds, an old mp3 player, microcontroller and "optional" LED display. Important notice, there is no touch screen (capacitive nor resistive) :)
