Authentification and authorization device

Abstract

Authentication and authorisation device of a firearm ( 11 ) that comprises an emitting device ( 20 ) carried by an authorised operator ( 15 ) and a receiving device ( 21 ) that unblocks and blocks the use of the firearm ( 11 ) based upon a selectable electrical characteristic related to the authentication and authorisation signal generated by the emitting device ( 20 ) carried by an authorised operator ( 15 ).
