The authentication unit 3433 transmits electronic device information S20 to the unmanned aerial vehicle 60 in response to the successful authentication. The unmanned aerial vehicle 60 performs authentication processing based on the electronic device information S20. For example, when the identification information of the electronic device 34 matches the identification information of the electronic device 34 included in the flight plan information, the unmanned aerial vehicle 60 determines that the authentication has been successful. The unmanned aerial vehicle 60 transmits power supply request information S22 to the electronic device 34 in response to the successful authentication.

[0033] The control unit 3431 outputs power supply command information S24 to the power supply device 37 in response to receiving the power supply request information S22 by the wireless communication unit 342A. The power supply device 37 supplies power based on the power supply command information S24. The power supply unit 64 of the unmanned aerial vehicle 60 can be charged by power supply from the power supply device 37.

The user terminal device 70 presents the billing information S32 to the user, and executes payment based on the user's operation.

[0035] Fig. 8 is a sequence diagram showing an example of a processing procedure between the unmanned aerial vehicle 60 and the user terminal device 70, and the electronic device 34 in the embodiment. In the processing shown in Fig. 7, the unmanned aerial vehicle 60 flies to the electronic device 34 to supply power, but is not limited to this. For example, when the unmanned aerial vehicle 60 owned by a user is charged by the electronic device 34, power supply may be controlled by communication between the electronic device 34 and the unmanned aerial vehicle 60 and the user terminal device 70.

[0036] First, the unmanned aerial vehicle 60 outputs activation trigger information in response to approaching the vicinity of the electronic device 34 (step ST100).
