1. An apparatus configured for receiving inductive energy and providing power to a host device, comprising:

  • a memory for storing computer readable data relevant to receiving the inductive energy;

    a processor unit for processing the computer readable data and for processing data communications with a computer system, wherein the processor unit is programmed to operate in a polling listening mode;

    a coil controlled by the processor unit to receive an inductive data communication by listening for an inductive source to alternate between an energized and a de-energized state at regular intervals while in the polling listening mode and configured for receiving the inductive energy;

    a power supply operatively coupled to the coil and receiving the inductive energy from the coil, the power supply configured to convert the inductive energy from the coil to a direct current; and

    a power port for receiving the direct current from the power supply and outputting the direct current from the power supply to a host device.
