Embodiments of the present invention will be described below with reference to the drawings. 2 and 3 show the format of data recorded on the registration information recording card used in the shared code registration system according to the embodiment of the present invention and the configuration of the reader / writer device.

As shown in FIG. 2, a card ID data 10, a registration flag 11 and a group code data 12 are recorded on the registration information recording card 1. The data recording method may be magnetic recording, optical recording, or the like.

Further, as shown in FIG. 3, the reader / writer device 2 has a shared table 20 for storing code data of a group (hereinafter referred to as a “registered group”) in which the reader / writer device 2 can be used, and a card ID identification section. 21, a registration flag identifying unit 22, a code data identifying unit 23, and a buffer memory 24. Although not shown, it goes without saying that the reader / writer device 2 includes a data reading unit (magnetic head, optical pickup device, etc.) for reading the data of the registration information recording card 1, a data processing system for processing the read data, and the like. Yes.

The card ID data 10 recorded on the registration information recording card 1 is data indicating that the registration information recording card 1 is an information recording card that can be used by the reader / writer device 2, and is code data of a registration group. Equivalent to. The registration flag 11 is the data in which the code data 12 should be stored in the shared table 20 or the shared table 20.
Indicates whether the data should be deleted from.

The card ID identifying section 21 of the reader / writer device 2 reads the card ID read from the registration information recording card 1.
The data is collated with the code data stored in the shared table 20. The registration flag identifying unit 22 determines, based on the registration flag 11, whether the code data 12 recorded in the registration information recording card 1 is stored in the shared table 20 or deleted from the shared table 20. Code data identification unit 2
If the registration flag identifying unit 22 determines that the code data 12 is stored in the shared table 20, the code 3 is sent to the buffer memory 24 and stored in the shared table 20.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. In the figure, when the registration flag 11 is "a", the code data corresponding to the code data 12 is deleted from the shared table 20, and when the registration flag 11 is "A", all the code data is deleted from the shared table 20. When it is deleted and the registration flag 11 indicates the number of code data 12, it indicates that the code data 12 should be stored in the shared table 20.

First, when the registration information recording card 1 on which the card ID data 10, the registration flag 11 and the code data 12 are recorded is inserted into the reader / writer device 2, the card ID
The identification unit 21 inspects the card ID data 10 (step S1). Then, when the card data corresponding to the card ID data 10 is not stored in the shared table 20, the registration information recording card 1 is ejected (step S9), and when stored, the registration flag identification unit 22 causes the registration flag identification unit 22 to register. Is identified (step S2).

If the registration flag 11 is "a", the code data corresponding to the code data 12 is stored in the shared table 20.
It is further deleted (step S4). If the registration flag 11 is "A", all code data is deleted from the shared table 20 (step S6). If the registration flag 11 indicates the number of pieces of code data 12, the code data identification unit 23 stores the code data 12 in the shared table 20 via the buffer memory 24 (step S8).

With the above, the registration process of the code data according to the present embodiment is completed, and the registration information recording card 1 is ejected (step S9). Therefore, after the main registration processing, only the information recording card in which the code data corresponding to the code data stored in the shared table 20 is recorded by the main processing can be used in the reader / writer device 2. It should be noted that when the registration information recording card 1 is ejected from the reader / writer device 2 after completion of the registration process, a punch hole is punched in the registration information recording card 1 for security purposes to indicate that the registration information recording card 1 has been used. The content of the code data stored in the shared table 20 may be printed on the registration information recording card 1 in order to confirm whether the registration process is performed correctly.

[0015]

As described above, according to the present invention, one or a plurality of groups of code data and whether the code data is stored in the shared table or deleted in the information recording card which can use the reader / writer device. A step of recording a registration flag indicating another, a step of reading the code data and the registration flag recorded on the information recording card with the reader / writer device, and the reader / writer device, in the common table according to the read registration flag. By including the step of rewriting the stored code data, the group sharing the information recording card can be easily registered, and the configuration of the group can be changed. Further, even if the reader / writer device is not connected to a network such as a POS system, the information recording card can be shared without any problem.
