Abstract:
In some embodiments, apparatuses and methods are provided herein useful to track objects on a moving conveyor system. In some embodiments, an RFID based tracking system comprises a conveyor system to move and transport objects along a conveyance path, wherein each object includes a near field only RFID tag associated therewith and identifying the object. Each near field only RFID tag is not coupled to a far field antenna such that it is not readable in a far field of RFID communication and communicates only in a near field of RFID communication. An RFID tag reader is positioned to attempt to read the near field only RFID tag of each object. And a control circuit processes reads of the near field only RFID tags by the first RFID reader to determine an order of the objects being conveyed.
