A system tracks assets using RFID tags. A plurality of RFID readers use different frequencies to read RFID tags. A plurality of assets each have a RFID tag coupled to them. The RFID tag changes a response frequency as a function of a next RFID reader scheduled to track the corresponding asset. Assets may be components in an assembly line, patients in hospitals, containers, or other things that need to be tracked at different locations.
