Abstract
As an alarm reception flag offers an “ON” state indicating that a sign of an occurrence of abnormality on a digital cash module associated with the alarm reception flag is detected, a control unit of a digital cash safe performs on a priority basis a processing for transfer of digital cash data to an IC card, which is the primary service of the digital cash safe, and simultaneously performs a save processing for digital cash data stored in the digital cash module on which a sign of abnormality is detected.
