Wisconsin investigation turns up slot machine jamming device from overseas: CPB
Fox News
U.S. Customs and Border Protection (CBP) officers in Wisconsin recently seized a slot machine jamming device while inspecting a shipment from Hong Kong.
The ElectroMagnetic Pulse (EMP) devices, which are prohibited by the Federal Communication Commission, are used to "jam" the inner workings of a slot machine.
EMP generators create electromagnetic pulses to disrupt electronics from about a meter’s range, according to CBP. The devices send an electric current through a magnetic field – often with a magnetic copper wire.
