An objective of the present invention is to simplify reuse of an IC card (3) which has been rendered invalid and has validity information which denotes the invalidity written thereupon. Provided is a terminal device, comprising a list storage means and a recording means. The list storage means stores a whitelist wherein are associated an invalidity iteration specification value and an identifier of a recording medium which stores the identifier, a setting value, and validity information which denotes validity or invalidity. The recording means reads from the whitelist the invalidity iteration specification value corresponding to the identifier which is read out from the recording medium, compares same with the setting value which is read out from the recording medium, and, if the setting value and the invalidity iteration specification value are equivalent, executes a validation process which stores, upon a recording medium, validity information which denotes validity together with a prescribed process. |
