A terminal device for use in a software rewriting system configured to rewrite a software package of a control device mounted on a movable object, including: a wide area communication unit configured to communicate with a server via a wide area network; a storage unit; and a short-range wireless communication unit configured to communicate with the movable object via a short-range wireless communication network. The updating software package is received, via the wide area network and the wide area communication unit, from a server including an updating software database storing the updating software packages for updating the software package of the control device. The updating software package received from the server is stored in the storage unit. The updating software package stored in the storage unit is transmitted to the movable object, via the short-range wireless communication unit and a short-range wireless communication network.
