The itinerary data includes one or more checkpoint times when the RFID module is expected to receive a data transmission. The processor is further arranged, when not detecting a data transmission at a checkpoint time of the itinerary data corresponding to the current time, to activate the positioning sensor to collect the location of the tracking device, and activate the wireless connection module to connect. |
