Abstract
A terminal device has a network interface that forces network connection when not connected to a network. The terminal device that has a network interface includes a connection check unit that makes a check as to whether the terminal device is connected to a network, and an invalidation unit that, when the connection check unit judges that the terminal device is not connected to the network as a result of the check, invalidates a function included in the terminal device.
