A locating system for locating a specific subject among a number of possible subjects having an RFID tag attached to subjects which, when interrogated by an RFID reader, provides a unique identification code. A database containing information about subscribers including a list of RFID tag codes associated with the subjects of interest is included in the system. Transceivers having an RFID reader and a processor responsive to the transceiver and the RFID reader are also included in the locating system for locating a subject of interest. When the transceivers receive RFID code transmitted via the communications network, the transceiver is activated to transmit data to any nearby RFID tags. Upon receipt of a response from the RFID tag, the transceivers transmit the tag data to the communications network so that the subject of interest can be located.
