An apparatus for selecting, monitoring, and controlling electrically
powered devices is disclosed. In one embodiment, the apparatus includes
an electrically powered device having a key operating line and switching
control circuitry to control usage of the electrically powered device by
interrupting continuity of the key operating line. In another embodiment,
the apparatus monitors usage of an electrically powered device. The
apparatus includes a circuit which is coupled to the device to provide a
power output of the device, an analog to digital converter coupled to
receive the power output and convert the same to digital form, and a
controller to receive a user input, process the user input by
establishing communication with a remotely located device to request
approval of a financial transaction, and generate control signals in
response to receiving approval. The controller receives the digital form
of the power output and monitors the operation of the electrically
powered device.
