Apparatus () and a method for rendering a weapon () incapable of use unless authorized by a specified individual. More than one person may be authorized to use the weapon, however only one person may be authorized to use it at any one time. Each authorized person carries a badge () or other device which includes an rf transmitter (TAU) capable of transmitting a coded signal to a receiver (REU) installed in the weapon in response to a coded query from a unit (EU) installed in the weapon. If a properly coded transmission is received by the weapon, it becomes capable of being fired by the person who authorized its use. However, the weapon will not fire unless the person using the weapon is also standing behind the weapon. This prevents the weapon from being turned on the person authorized to use it. The apparatus stores details of the weapon's use (e.g., who, when, and where). This information is released upon receipt of an authorized code.
