At this time, the control unit 50 stores the image photographed by the camera unit 20 for a preset time.

Further, the control unit 50 controls the reader 10 to emit a beam toward the tag of the traffic card 60. The reader 10 then irradiates the beam toward the tag in a plurality of directions (S20).

In this case, the reader 10 irradiates the m × n beams in the boarding and landing areas of the door 72, ie, the boarding direction and the door opening / closing direction, so as to perform RF communication with the traffic card 60 of the entire boarding passenger .

When the beam is irradiated, the reader 10 combines the signals received from the tag to acquire beam steering information in the direction of the tag, and then, through the beam steering information and the tag information of the tag, (S30), and continuously tracks the position of the detected traffic card 60 (S40).

In this case, the controller 50 receives the position of the traffic card 60 detected and tracked by the reader 10.

Meanwhile, in the above process, the DCU 30 receives the door control command from the vehicle control computer, closes the door 72, and inputs the state of the door 72 to the control unit 50.

The control unit 50 checks whether or not the door 72 is closed in the above-described process (S50).
