Abstract
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.
