Abstract: A system for identifying a carrier vehicle and piggyback vehicles positioned thereon. Each of the vehicles is equipped with an information-coded label, the information encoded in the carrier vehicle label and in the piggyback vehicle labels including features distinguishing the two types of labels and, therefore, the two types of vehicles, from each other. As the carrier and piggyback vehicles move through a label-reading area, a scanning apparatus senses the information encoded in the various labels and produces successive signals representative of the information. These signals are then processed by signal processing circuitry and applied to and stored in succession in a main data register. The signals stored in the main data register are examined by detection logic circuitry to determine the nature thereof, that is, whether carrier vehicle information or piggyback vehicle information, and, based on these determinations, selectively steered into a ''''carrier'''' register or into a ''''piggyback'''' register and stored therein. Each signal applied to and stored in the ''''piggyback'''' register is read out therefrom shortly after being stored therein but prior to the departure of the carrier and piggyback vehicles from the labelreading area. The signal stored in the ''''carrier'''' register is read out in response to the departure of the carrier and piggyback vehicles from the label-reading area. Timing circuitry is also provided in the system for preventing multiple readings of a piggyback vehicle label.
