An electronic money system offline and terminal line terminal are mixed, it is intended to perform fault recovery as appropriate. In both of the center and server electronic money card, I will prepare a flag that can be set selectively two values ​​and "trading in" and "closing".

In the case of a failure during the treatment, the state of the flag at the time of failure is stored in both, it is possible to determine when a failure has occurred from these states.
