Abstract: There is provided a monitoring device for a tracking system adapted for use in at least one vehicle. An exemplary monitoring device comprises a communication circuit adapted for communication with at least one radio frequency identification (RFID) tag on an article to be transported by the vehicle and a position system (PS) circuit adapted for determining a location of the vehicle. The exemplary monitoring device also comprises a control circuit having a microprocessor and a memory, the control circuit being electrically connected to the communication circuit and the PS circuit, the microprocessor being adapted to acquire the RFID tag data and the location data in the memory, to operate the communication circuit to interrogate the RFID tag, to operate the PS circuit to determine a location of the vehicle, and to associate the RFID tag data with the location data of the vehicle. The exemplary monitoring device additionally comprises an alarm electrically connected to the microprocessor.
