<p>PURPOSE:To easily register a group sharing an information recording card, to cope with the change of the constitution of the group and to realize the shared use of the information recording card without any problem even when the reader/writer is not connected to a network such as a POS system. CONSTITUTION:The system consists of a step recording the code data of a single or plural group(s) as well as a registration flag indicating whether the code data are stored in or deleted from a common table 20 in an information recording card 1 which can use a reader/writer 2, a step reading the code data and registration flag recorded in the card 1 with the reader/writer 2, and a step rewriting the code data stored in the common table 20 corresponding to the read registration flag.</p> |
