ABSTRACT:
In a card-type storage medium and transaction apparatus, when a transaction is started between the card-type storage medium and the transaction apparatus and a data file that is an object of an access from the transaction apparatus is determined, a unique identifier generating device of the card-type storage medium generates a unique identifier for this transaction. A unique identifier notifying device notifies the unique identifier to the transaction apparatus. Accordingly, it is possible to specify the transaction apparatus having access to the card-type storage medium by referring to that unique identifier.
