Locations and conditions of objects within a working environment may be tracked using RFID signals. A working surface within the environment may include a plurality of RFID antennas, and the objects to be tracked may include RFID tags. When one of the objects passes within an operational range of one of the antennas, an RFID signal is transmitted from the tag on the object to the antenna, and the location of the object may be determined based on the location of the antenna. Additionally, where a plurality of tags that are specially associated with a different aspect of a condition of an object are provided thereon, the condition of the object may be determined based on a number of the tags from which RFID signals are received, and the aspects of the condition with which each of such tags is associated.
