Abstract: This invention is a firearm automatic locking system and method using an emitter that produces an alternating electromagnetic field to induce an eddy current in an encoder presented by an authorized user of the firearm. A sensor in the firearm detects a unique signature of the eddy current, which unique signature is based on any combination of the size, weight, composition and shape of the encoder, which is typically a ring worn by the authorized user. The eddy current signature is then compared electronically to a pre-determined value. If the signature and value are equivalent, a power circuit is closed providing an electrical current to an electrical device, thereby mechanically enabling the firing mechanism of the firearm. As long as the encoder is in adequate proximity to the automatic locking system, the weapon can be fired. To conserve battery power, the automatic locking system is activated only when a magnetic reed switch is activated.
