1. A firearm safety enhancement system for preventing use of a firearm except by an authorized individual comprising:

  • a. at least one electrically activated preventer having a first position for preventing use of said firearm and having a second position for permitting use of said firearm;

    b. an electrical activation circuit operatively connected to said preventer to move said preventer between said first and second positions;

    c. a portable power supply coupled to said activation circuit for providing power thereto;

    d. a power signal transmitter operatively connected to said power supply for transmitting an electromagnetic power signal at a predetermined regular frequency;

    e. a passive identification tag mounted to a personal adornment carried or worn by an individual and preprogrammed with an identification code preselected from a large number of available identification codes, said passive identification tag being responsive to said power signal to actively impose a return signal on said power signal representative of said preprogrammed identification code so that said power signal acts as a carrier of said imposed code signal; and

    f. a reader circuit connected to said power signal transmitter and to said electrical activation circuit, said reader circuit responsive to said return signal to activate said electrical activation circuit, to provide power from said portable power supply to move said at least one preventer between said first preventing position to said second position for permitting use of said firearm, when the reader circuit determines that the identification code represented in the return signal matches an authorization code stored in the reader circuit.
