Further, although not shown, a control unit including a CPU for performing overall control is provided.

In such a configuration, the operation is shown in FIG.
This will be described with reference to the flowchart of FIG.

When the system is started, the ID number, identification symbol and fraud prevention data of the card 100 are registered in the memory 11 of the center computer 1 in advance in the format shown in FIG. This data registration needs to be performed for all issued cards, and may be performed by the reading unit of the card processor shown in FIG.
May be performed directly. Card processing machine (2
1 to 2n and 31 to 3n), the card 100 is inserted into a card insertion slot (not shown) of the card processing machine, so that the I
The D number “ABCD” is read by the ID reading unit 211, the identification symbol “1234A” of the identification symbol recording unit 110 is read by the identification symbol reading unit 212, and the unauthorized data of the unauthorized data recording unit 111 is read by the unauthorized data reading unit 213. Read in
The read data is sent to the memory 11 via the transmission unit 214 and registered. Such registration is performed for all cards issued for use by the system. The ID numbers, identification symbols, and fraud prevention data are different for all cards.

After the above-described registration, when the card 100 is used, for example, for lending a ball at a pachinko parlor, the card 100 is inserted into, for example, a card insertion slot of the card processor 21. By inserting the card, the card processor 21 is inserted.
Reads the ID number “ABCD” of the card 100 into the ID reading unit 2
In step 11, the identification symbol “1234A” is assigned to the identification symbol reading unit 21.
In step 2, the fraud prevention data is read by the fraud prevention data reading unit 213 (step S1). The read identification symbol signal DS1 is input to the identification symbol determination unit 220, and the read fraud prevention data UP1 is input to the fraud prevention data determination unit 221. Further, the read ID number is sent to the memory 11 via the transmission unit 214, and it is determined whether or not there is an ID number registered in the memory 11 in advance (step S2). ID not registered in memory 11
In the case of a number, it is identified as a falsified card, and the
2 outputs an alarm (sound or light) (step S1).
0), the card 100 is taken inside, and the subsequent use is prohibited (step S11).

In step S2, if the read ID number is a number registered in the memory 11 in advance, the memory 11 calls the identification symbol signal DS2 and the fraud prevention data UP2 corresponding to the ID number ( Step S3), transmitting to the identification symbol discriminating section 220 and the fraud prevention data discriminating section 221 where the read data DS1
And UP1 (step S4).

If at least one of the identification symbol and the fraud prevention data does not match as a result of the verification, the card is identified as a falsified card, and the process proceeds to step S10.
Similarly, an alarm is output and the card is taken in and the subsequent use is prohibited (step S11). If both the identification symbol and the fraud prevention data match as a result of the collation, the card is determined to be a normal card, the normal processing based on the data of the data recording unit 102 is performed, and the identification symbol recording unit 11 is executed.
For example, the identification symbol “1234A” of 0 is rewritten as “1234B” as shown in FIG. 7 (step S6), and a part 111 of the fraud prevention data 111 as shown in FIG.
A is erased (step S7). The example of FIG.
The case where 1000 yen is used for 00 is shown. 8 shows an example in which the card 100 is further used and the used frequency reaches 2200 yen, and the frequency area 111 up to 2200 yen is used.
B has been erased.

The rewriting of the identification symbol may be a serial number in the case of a numeral, and it is sufficient that the identification symbol is not the same as another card in relation to a pair with an ID number. The identification symbol may be a circle, a triangle, a square, a simple figure, or the like in addition to a numeral, and may be in any form as long as it is rewritable and can be distinguished from others. Further, the fraud prevention data may be an array of barcodes or symbols in addition to the broken lines, and may be in any form as long as a part of the data can be erased.

When the identification code is rewritten to another identification code in accordance with a predetermined rule and a part of the fraud prevention data is deleted according to the frequency of use, the new data is sent to the memory 11 and re-written. It is registered (step S8).
Next, when the card 100 is used, it is collated with the identification symbol and the fraud prevention data re-registered in the memory 11. In other words, even if the data recorded on the card is copied, it cannot be used because it differs from the registered data, and if the card is used, the data is updated. It is also impossible to reproduce and use the first card (high value card) from a low or low value card.

As described above, according to the present invention, the identification code is rewritten each time the card is used, and a part of the fraud prevention data is erased and re-registered. It is impossible to do.

In the above-described embodiment, the fraud prevention data is indicated by one broken line. However, as shown in FIG. 9, a plurality of broken lines are recorded in the fraud prevention data recording unit 111.
You may make it select by changing the polygonal line used for every card. That is, as the card, only one of the plurality of polygonal lines is used as fraud prevention data. This makes it more difficult for a third party to grasp the card data. In addition to forming fraud prevention data with broken lines, FIG.
As shown in FIG. 5, a large number of arrays may be formed by characters or symbols, and one array to be used for each card may be selected. Also in this case, the number of characters or symbols to be erased may be changed according to the usage frequency. Further, in the above description, an example in which the identification symbol and the fraud prevention data are magnetically recorded or read has been described. However, identification using recording and rewriting (erasing) of optical data, wavelength detection based on color, and the like are considered. Can be

In the above description, the identification symbol and the fraud prevention data are registered in the memory of the center computer. However, if the area of use of the card is limited, it may be registered in the memory of the lower computer.

[0024]

As described above, according to the present invention, when a card is used, the identification symbol and the fraud prevention data of the card are compared with the identification symbol and the fraud prevention data of the card registered in advance in the memory. Therefore, it is possible to immediately and reliably determine whether the card is correct or not, and whether the card is reproduced or altered. Therefore, unauthorized use and alteration of the card can be prevented. Also, in the event of unauthorized use of the card, an alarm is output using an alarm means so that the card can be taken inside, and subsequent use is prohibited, so that unauthorized use or alteration of the card is more reliably prevented. be able to.
