A radio frequency identification (RFID) system and method for tracking and locating an RFID tag is disclosed. The system includes a reader, an identification tag, at least one sensor-tag and a data processing element. The reader is used to initiate a query for an object with an RFID tag. The identification tag is attached to the object. The RFID tag responds to the query. At least one sensor-tag is positioned near the RFID tag. The at least one sensor-tag functions to receive the response of the RFID tag. The sensor-tag determines whether the identification tag is within a predetermined sensor-tag range. Based upon this determination, the at least one sensor-tag communicates a response signal to the reader when the at least one sensor-tag receives a predetermined request signal from the reader. Based on the responses of the sensor-tags, the location of the object with the responding RFID tag can be calculated.
