A master controller for managing items tagged with radio-frequency identification (RFID) tags includes a transceiver to transmit interrogation signals to the RFID tags and to receive response signals from the RFID tags. The master controller may also include a processor to determine the proximity of tagged items based on signal levels of the response signals, and to notify a user when certain ones of the tagged items are in a predetermined relation to a proximity threshold.
