Beschreibung
Zusammenfassung:	L'invention concerne les techniques d'identification de personnes ou d'objets. Un dispositif d'identification comprend une étiquette (24), pouvant être fixée par exemple à une personne (12), et qui contient un transpondeur (26) qui génère et émet un signal d'identification RF sous l'effet de la réception d'une interrogation émise en RF; une station d'identification (16) comportant une antenne (33.1) et un capteur RF qui génère l'interrogation et qui reçoit le signal d'identification RF provenant du transpondeur et produit une indication de sortie représentant l'identification du transpondeur; et des moyens de commande qui commandent au capteur de générer sélectivement le signal d'interrogation, et qui reçoivent l'indication de sortie. Application à l'identification d'utilisateurs de systèmes informatiques. Apparatus identifying an instrumentality such as a person's hand or an article of merchandise, wherein the instrumentality carries a tag incorporating a transponder generating and transmitting a radio frequency identification signal in response to a radio frequency transmitted inquiry, a nest comprising an identifying station and incorporating a proximity sensor sensing the presence of the instrumentality at the identifying station and producing an indication of the presence or absence of the instrumentality, the identifying station comprising a radio frequency sensor portion generating a radio frequency transmitted inquiry transmitted to the transponder in response to sensing the presence of the instrumentality and receiving the radio frequency identification signal from the transponder, the proximity sensor terminating generation of the radio frequency transmitted inquiry when a clear and reliable output indication identifying the tag has been produced, and the proximity sensor also preventing, after producing a clear and reliable output indication, generation of a subsequent radio frequency transmitted inquiry until the proximity sensor has subsequently produced indications of the absence of the instrumentality at the identifying station.
