Abstract: A device is provided as part of a fuel cut-off system which includes a switch for selectively opening and closing the flow of fuel to an engine. Verification actuation information is received from an external source and compared with stored, predetermined actuation information and, provided there is a correspondence between the received and stored actuation information, selectively actuates the switch to shut off or open the flow of fuel to an engine. Moreover, the device may have the ability to cut off the flow of fuel at any time as controlled from an external source. The device may further include a clock to identify when the flow of fuel is to be shut off.
