Electric mobile vehicle, portable terminal device, and wireless communication program

A portable terminal device comprising:

• a wireless communication unit configured to perform short-range wireless communication;
• an obtainment unit that obtains a verification code notified from an electric mobile vehicle, as triggered by an operation performed by a user, wherein
• the electric mobile vehicle, to which a power storage pack is attached, comprises:
• (1) a vehicle-side controller that obtains the verification code from the power storage pack via wired or wireless communication, the verification code being to be used in a process of exchanging an encryption key that is to be used for short-range wireless communication between the power storage pack and the portable terminal device, and
• (2) a notification unit that notifies the user of the portable terminal device of the verification code obtained from the power storage pack and includes a display unit configured to display the verification code;
• and
• a controller that performs a process of exchanging an encryption key with the power storage pack using the verification code, the encryption key being used for the short-range wireless communication with the power storage pack, the power storage pack being attached to the electric mobile vehicle, wherein
• the obtainment unit includes an imager,
• as triggered by an operation performed by the user, the imager captures an image of the verification code displayed on the display unit, and
• the controller of the portable terminal device performs image recognition of the image captured by the imager, detects the verification code, and performs the process of exchanging the encryption key using the verification code detected.
