Abstract
A system for preventing unauthorized access to a firearm trigger includes a database of PIN numbers associated with a plurality of trigger locks and access tokens, each corresponding trio represented by an identification code. At purchase, a purchased firearm includes a two-piece trigger lock along with an access token. Each token includes a unique configuration of ferro-magnetic wires. If a background check of the firearm purchaser 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 a read head therein 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 release of the trigger lock.
