ABSTRACT:
This invention is to prevent a MAC of a correct answer from being calculated by use of an IC card even if count data in the database of a PC is falsified since the MAC calculated by the IC card is made invisible from the exterior of the IC card. Thus, falsification of data by enciphering the number (total sum) of cut sheets in a sheet checking equipment.
