Abstract
The in-vehicle apparatus card information stored in a storage section is set to an inactive state and is prevented from being read from the storage section when an ignition switch changes from “on” to “off” or when a user performs an operation signifying a change from an active state to the inactive state. Accordingly, the in-vehicle apparatus card information is disabled by an explicit user operation or a normal operation performed when the user gets out of a vehicle. It is possible to prevent the unauthorized use of the in-vehicle apparatus card information when the user does not get in the vehicle.
Claims19
An in-vehicle apparatus comprising:
- a charging execution section that communicates with a roadside apparatus and executes a charging process;
- a charging information storage section that stores charging information needed to execute the charging process by the charging execution section;
- and
- a setup section that assigns one of an active state and an inactive state to a state of the charging information stored in the charging information storage section, the active state corresponding to an available state of the charging information and the inactive state corresponding to an unavailable state of the charging information.
A semiconductor device characterized by assigning one of an active state and an inactive state to a state of charging information needed to execute a charging process, the active state corresponding to an available state of the charging information and the inactive state corresponding to an unavailable state of the charging information.
