1. An electronically controlled safety system for use in firearms comprising:
a trigger mechanism interface connected to, or otherwise incorporated into a firearm's trigger mechanism wherein the trigger mechanism interface comprises a point of connection;
a shape memory actuator module comprising at least one shape memory wire and a mechanical locking interface actuated by at least one shape memory wire wherein the mechanical locking interface is designed to connect to the point of connection of the trigger mechanism interface and immobilize the trigger mechanism when the mechanical locking interface is connected to the point of connection of the trigger mechanism;
a radio frequency identification module comprising a radio frequency identification reader configured to send a radio frequency interrogation signal and to receive a predetermined activation code;
a radio frequency identification tag configured to transmit the predetermined activation code when subjected to the radio frequency identification reader's interrogation signal received at or above a predetermined signal strength;
a control module configured to allow a current to flow to the shape memory actuator module when the radio frequency identification reader receives the predetermined activation code; and
a magazine and battery module configured to provide an electrical current to the shape memory actuator module, the radio frequency identification module, and the control module wherein the control module is configured to activate a vibration motor when the firearm is armed and ready to fire.
