Ic card transaction system

Abstract

Abstract PURPOSE:To relieve a file load of the center side by allowing an IC card itself to discriminate whether the procedure transmitted from the center is a new procedure or an old procedure to apply registration processing to a memory. CONSTITUTION:When inputted data is an operation procedure load request transmitted from the center, the processing for storing the operating procedure in a table MA is executed. Whether or not the procedure transmitted at first is stored already is discriminated. Since the procedures 1-7 are stored already, when a procedure No other than them is given, it is regarded as a new procedure No. and a new address of the operating procedure table MA is set to a pointer and transmitted data is stored. Further, a head address of new procedure storage area is stored in an area corresponding to a tank under service at present in the table index IM.
