Abstract: An electronic tag device for cargo or baggage comprising a housing, a microcontroller, a memory, a wireless communications module, and a sensor module. The microcontroller is configured to receive itinerary data via the wireless communications module while the microcontroller is operating in a first mode and store the itinerary data in memory. The itinerary data may include at least a place of departure, a departure time, a place of arrival, and an arrival time. The microcontroller is further configured to enter a second mode based on at least one of the departure time in the itinerary and sensor data received from the sensor module, wherein the wireless communications module is disabled in the second mode, and return to the first mode based on at least one of the arrival time in the itinerary and sensor data received from the sensor module. The microcontroller will communicate with a remote system using the communications module while in the first mode and turn off all communication while in the second mode.
