When the goods are accepted, customers print a label with readable barcode. We make our labels look exactly the same, with the only exception being that we add a little chip with information relative to that piece, which can be read by antennas in the ceiling. CargoAware is passive, so the antennas just track the movements of any RFID chips that move through a facility in three dimensions. With the data on chip, we know where it's been and we can message it back to the customers warehouse to tell them that the goods have been seen on the export dock, and that they are now in the storage area awaiting buildup. And we also develop rules-for instance, if you tender goods for a specific flight time, and we have not seen these goods yet at the buildup by a certain deadline, then the system will send out a warning. These are all things that we can do with the real-time tracking.
