A electronic tag device is provided and includes: a processor; a memory connected to the processor and stored with multiple sets of tag data; a wireless data transmission circuit connected to the processor and used to connect an electronic device; a radio frequency identification (RFID) tag chip connected to the processor; a cellular communication circuit connected to the processor and provided with a subscriber identity module (SIM) interface used to connect a SIM card; and a positioning circuit connected to the cellular communication circuit. When a geographical region where the electronic tag device is located changes, the electronic tag device can automatically select a target set of tag data corresponding to a current geographical region from the multiple sets of tag data for data updating, thereby avoiding an additional expense for toll settlement.
