A firearm safety enhancement system is provided for enabling use of a firearm only by an authorized individual. At least one electrically activated preventer is provided having a first position for preventing use of firearm and having a second position for enabling use of the firearm. An electrical activation circuit is operatively connected to the preventer to move the preventer between the first and second positions. A portable power supply is carried in said firearm and is coupled to the activation circuit for providing power. A power signal transmitter is operatively connected to the power supply for transmitting an electromagnetic power signal at a regular frequency. A passive identification tag is mounted to a personal adornment to be carried or worn by an individual and is preprogrammed with an authorized identification code preselected from a large number of available identification codes. The passive identification tag is responsive to the power signal to impose a coded return signal on the power signal. The return coded signal is representative of the preprogrammed authorized identification code so that the power signal acts as a carrier of the imposed coded return signal. A reader circuit is connected to the power signal transmitter and to the electrical activation circuit. The reader circuit is responsive only to an authorized identification code to activate the electrical activation circuit to provide power from the portable power supply to move the at least one preventer between the first preventing position and the second unblocked position for enabling use of the firearm.

[ What is claimed is:] [1.]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; andf. 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.
