A system and apparatus for preventing unauthorized access to a trigger of a firearm comprises a database of PIN numbers associated with a plurality of trigger locks and access tokens, each corresponding trio being represented by a common identification code. At a point of purchase, a consumer receives a two-piece trigger lock secured about the trigger of a purchased firearm as well as an access token. Each token includes a unique number or configuration of ferro-magnetic wires. Each trigger lock includes a magnetic read head which generates voltage pulses when a token is positioned in close proximity thereto. This positioning causes the ferro-magnetic wires to switch magnetic states, thus invoking electromagnetic impulses. If a background check of the firearm purchaser, initiated at the point of purchase, is approved, a central computer coupled to the database and to a computer network displays a personal identification number (PIN). Entry of this PIN into a keypad on a corresponding trigger lock actuates the read head and a token may be positioned thereby. A processor coupled to the read head is able to determine if the trigger lock and token match and, if so, to actuate a release of the trigger lock from about the trigger.

1. An electronic trigger lock for preventing unauthorized access to a trigger of a firearm, comprising:a housing having a first section and a second section, said first section defining an interior space; means for releasably coupling said second section to said first section of said housing; a token having a token body and at least one ferro-magnetic wire disposed in said token body; a read head disposed in said interior space of said first section and adapted to generate a plurality of output pulses in response to a switch in magnetic state of said at least one ferro-magnetic wire of said token upon said token being proximately aligned with said read head; a processor mounted in said interior space and coupled to said read head for receiving said plurality of output pulses, said processor adapted to calculate an actual value representing the number and duration of said plurality of output pulses and to compare said actual value with a predetermined value, said processor adapted to deliver a signal to said coupling means when said actual value matches said predetermined value so as to release said second section from said first section; a numeric keypad disposed on said housing for receiving a manually input personal identification number from a user; and comparator circuitry disposed within said interior space of said first section and coupled to said keypad for comparing said personal identification number with a predetermined access number, said comparator circuitry adapted to energize said read head when said personal identification number matches said access number.
