FIG. 3 is a block diagram of a registration unit of the device, FIG. 4 is a block diagram of a verification unit, an alarm unit and an erasure unit of the device, and FIG. 5 is a back view of a card used in the method.

The card 1 is, for example, a telephone card. In the central portion of the back surface 20 of the card 1, as shown in FIG. 5, the frequency of use is displayed in the longitudinal direction of the card 1 by processing such as magnetism, magnetic field, sound wave, vibration wave, optical and radiation. Many polygonal lines (marks) 21 are provided.

The polygonal line 21 indicating the frequency of use is selected, for example, according to the type of card used, the date and time of use, and the like, and the usage is deleted according to the frequency of use. On the back surface 20 of the card 1, an identification mark 22 for identifying the card 1, for example, a numerical value 1467AB is provided.
(Reading code) is attached to one side. Therefore, the type of the card 1 and the card itself can be specified by the identification mark 22.

On the other side of the card 1, a read incoming code 23 is given by a numerical value. Further, an encoder 24 is provided for punching a punched hole when used. Therefore, when the card 1 is used, punch holes are formed in the encoder 24 in accordance with the frequency of use.

The shape of each polygonal line 21 used when the card 1 is used is, for example, 00001-, so that the position of the line can be displayed by X and Y coordinates so that the reader 2 and the computer of the registration means 3 can read the line. Is stored.

First, when making a call by inserting the card 1 into the reader (telephone) 2, for example, the reader 2 reads the identification mark 22 of the card 1 and the frequency of use of the card 1 (step S1).

The identification mark 22 of the card 1 by the reader 2
The reading of the usage frequency of the card 1 is performed every time the card is used.

The identification mark 22 of the card 1 read by the reader 2 and the frequency of use of the card 1 are sent as signals to the registration means 3, recorded by the recording means 7 of the registration means 3, and further stored by the storage means 8. be registered. This storage registration is performed every time the card 1 is used (step S2).

When the card 1 is used, a broken line segment corresponding to the use frequency is deleted according to the use frequency. As a result, data corresponding to the use of the card 1 is deleted.

When the identification mark 22 and the frequency of use coincide with the identification mark 22 and the frequency of use of the registered card 1, the permission means 9 permits the card 1 to be used.
(Step S5).

On the other hand, if the identification mark 22 and the frequency of use do not match the registered identification mark 22 and the frequency of use of the card 1, an alarm is issued by the alarm device 10 of the alarm means 5 (step S6). Further, the data of the card 1 is completely erased by the data eraser of the erasing means 6 (step S7).

In this embodiment, when the card 1 is used, the identification mark 22 and the frequency of use of the card 1 are compared with the identification mark 22 of the card 1 registered in the registration means 3 and the frequency of use. I do. Therefore, it can be determined whether the card 1 is correct or not, and whether the card 1 has been reproduced or altered.

When the card 1 is illegally used, a warning is displayed, and when the card is illegally used, the data on the card 1 is completely deleted, so that the card 1 cannot be used thereafter. Therefore, unauthorized use and alteration of the card 1 can be prevented.

In the above embodiment, the identification mark 22 of the card 1 is continuously used as the identification mark registered first. However, a new identification mark is provided on the card 1 every time the card is used, and this new identification mark is used. Registration means 3 for each card use
The identification mark and the frequency of use of the card 1 may be compared with the registered new identification mark and the frequency of use each time the card 1 is used next time.

For example, the serial number of the card is recorded in the main computer, and the serial number of the card is stored in a new card. The serial number recorded on the new card is canceled at the same time as the card is used by the machine used (for example, a pachinko machine) by the command signal from the main computer immediately.

As a result, the number assigned to the original card is lost, and a new number is assigned to the same card. At the same time, the old number disappears in the main computer, and the pair number is registered as a new number. In this way, a series of new numbers are recorded on the card and the same number does not exist, forming an ID system for the card, thereby preventing unauthorized use or alteration of the card.

In other words, since the ID system is formed by the card and the main computer, the identity of each card can always be confirmed by the main computer.

In this case, at the time of the next use,
The identification mark and the frequency of use of the card 1 are compared with the registered new identification mark and the frequency of use, respectively.
It becomes more difficult to alter the card 1 and illegal use or alteration of the card 1 can be prevented more reliably.

FIG. 6 is a rear view of a card showing another example of a card according to another embodiment of the present invention. In the case of this example, one polygonal line displayed on the
6 is used for the identification mark of the card 1 and the frequency of use, in which a different polygonal line is selected for each use of the card.

That is, the complicated saw-shaped polygonal line is used as an identification mark of the card 1 and as a display of the frequency of use. In addition, each time the card 1 is used, a different polygonal line is used, and the used amount is deleted according to the frequency of use.

With this usage, it is difficult to decode the data contents of the card 1, and the modification of the card 1 can be almost certainly prevented.

When the card of the present invention is manufactured at low cost, the identification mark of the card may be a simple figure such as a circle or a triangle or a small number of figures, and the frequency of use may be a figure such as a bar code. And so on.

FIG. 7 is a back view of a card which is an embodiment in which "symbols" are used as identification marks.
For example, the combination symbol 27 is erased by a designated number, erased by changing the designated number, erased only by the designated number, or erased by a certain combination.

Then, these erased symbols are stored in the main computer, and illegal actions are prevented as pass-through approval symbols when the next card is inserted.

Incidentally, as means similar to identification by "symbols", identification using wavelengths such as optical and color can be considered.
