Abstract
(EN)
A method of operating a radio frequency identification (RFID) reader device is presented. The method begins by operating the RFID reader device in a read-only mode, during which the RFID reader device does not generate tag interrogation signals. The method continues by receiving a tag response signal generated from an RFID tag being interrogated by an interrogator device that is distinct and separate from the RFID reader device. The tag response signal is received by the RFID reader device while it is operating in the read-only mode. The method continues by determining a location of the RFID tag, wherein the location is determined based at least in part on information associated with the received tag response signal.

L'invention concerne un procédé de fonctionnement d'un lecteur d'identification par radiofréquence (RFID). Le procédé commence par le fonctionnement du lecteur RFID en mode lecture seule au cours duquel le lecteur RFID ne génère pas de signaux d'interrogation d'étiquettes. Le procédé se poursuit par la réception d'un signal de réponse d'étiquette généré par une étiquette RFID interrogée par un dispositif interrogateur qui est distinct et séparé du lecteur RFID. Le signal de réponse d'étiquette est reçu par le lecteur RFID pendant qu'il fonctionne en mode lecture seule. Le procédé continue en déterminant un emplacement de l'étiquette RFID, l'emplacement étant déterminé d'après au moins en partie les informations associées au signal de réponse d'étiquette reçu.
