Sends an EMP (Electro Magnetic Pulse) out and destroys the RFID (Radio Frequency Identification) tag.
Looks like a good thing to do to those “Big Brother” type tags that are in passports and licenses. I don’t buy the whole “it saves valuable time” excuse. Whats wrong with passports still using bar codes, or various other look up methods that don’t emit short range broadcasts of information?
The flashing light and sounds effects are a nice touch.
Definitely something you wont find in RFID for Dummies
