Reference numeral 15 denotes an incoming circuit for detecting an incoming signal arriving at the line L, 16 a keyboard such as a dial key, 17 a memory, 18 a transport of an inserted prepaid card (hereinafter, referred to as a card), and a transfer of information to the card. A card reader 19 that performs recording and reproduction is a CPU that controls the above-described units. In addition, HS1, HS2
Is a hook switch, and RL is a relay.

In the public telephone 1 constructed as described above, when the card is off-hook and the card is inserted into the card reader 18, the card is conveyed in the conveyance path of the card reader 18 and reaches a predetermined position. Each information recorded on the card is checked via a head (not shown). If the result of this check is normal, the call service by this card is permitted, and subsequently, the dial number input by operating the keyboard 16 is output to the dial transmitting circuit 12 and transmitted as a dial signal to the line L. I do. As a result, the other party is called and the call service is started by the other party's response. During a call, the value information corresponding to the service is integrated by a charging signal or autonomous charging arriving at the line L, and when the call is completed, the balance information is recorded on a card and discharged.

[0009] In the recording area of such a card, in addition to the residual count data area in which the above-mentioned balance information is updated and recorded, card identification data such as the manufacturing date and serial number of the card is recorded. A data area is provided. It is also under study to provide an area for recording value information at the time of issuing a card as a measure against unauthorized use of the card.
However, in this case, in the case of a high-priced card, the value of the value information also increases, so that there is a problem that the recording capacity of the card is exceeded and the card becomes expensive. Therefore, in the present invention, the value information at the time of issuing the card can be recorded without increasing the capacity of the card recording area, and the validity of the card can be accurately determined by the public telephone 1 when using the card.

FIG. 2 is a diagram showing the configuration of the above-mentioned card. In FIG. 1, the card 2 has a recording area 3, and the recording area 3 records a card identification data area 3A in which card identification data such as a manufacturing date and a serial number are recorded, and residual count data of the card 2 are recorded. Remaining frequency data area 3

In order to record the value information (frequency) at the time of card issuance without exceeding the capacity of the recording area 3 even for a high-priced card, information in which the frequency is coded is recorded in the frequency code area 3B at the time of issuance. It was made.

[0011] In this case, when the card 2 is issued with, for example, "50" frequency, it is issued with "50" in the remaining frequency data area and the code data "1" in the frequency code area 3B at the time of issuance. Is recorded. Also, for example, when issued with “100” frequency, “100” is stored in the remaining frequency data area, and the frequency code area 3 at the time of issuance.
In B, code data “2” is recorded correspondingly. Further, when issued with "200" frequencies, "200" is stored in the residual frequency data area, and code data "3" is stored in the frequency code area 3B at the time of issuance.
Is recorded.

As described above, since the coded data such as "1", "2", "3",... Is recorded in the issue frequency code area 3B, the value information is recorded as it is. The capacity of the region 3B can be reduced much more than in the case. Further, the code information recorded in the area 3B can cover 16 types of issuance cards with a capacity of 4 bits, so that there is no practical problem.

On the other hand, when such a card 2 is used, the public telephone 1 which checks each information of the card 2 and judges whether or not the card 2 is used is stored in a memory 17 in a frequency code area when the card 2 is issued. Each of the code data “1”, “2”, “3”,... Recorded in 3B and the frequency data “50”, “100”,
"200",... Are stored in pairs.

When the card 2 is inserted, the CP
U19 stores the code information of the frequency code area 3B at the time of issuance of the card read through the card reader 18 and the memory 17
, And the remaining frequency data in the memory 17 corresponding to the detected code information is determined as the initial frequency data of the card 2. Then, the data value in the remaining frequency data area 3C of the read card 2 is
When the frequency data value is equal to or less than the frequency data value in the memory 17, this card 2
Is judged to be normal and the call service is permitted.

FIG. 4 is a block diagram showing the structure of a card issuing device 20 for issuing such a card 2. In the figure, 21 is an operation unit such as a keyboard, 22 is a printer, 23 is a control unit such as a personal computer, 24 is a raw card storage unit for storing raw cards on which frequency data and the like are not recorded yet,

The operation of the main part of the present invention will be described in more detail according to this flowchart. When the card 2 is inserted, the card 2 is conveyed through the conveyance path in the card reader 18 as described above, and when the card 2 reaches a predetermined position, the conveyance is stopped. In this case, the CPU 19 reads data (production date, serial number, etc.) in the card identification data area 3A of the card 2 via a head (not shown) in the card reader 18 (step S).
1).

Next, the CPU 19 checks whether the read card identification data is correct (step S2). And
If the check result of the card identification data is normal ("Y" in step S3), the CPU 19 reads the code information of the frequency code area 3B at the time of issue of the card 2 via the head (step S4). The read code information is the above-described code data “1”, “2”,
By checking whether any of “3”,... Is applicable (step S5), it is determined whether the code information is correctly read.

If the code information of the issue frequency code area 3B is correctly read and the check result is normal ("Y" in step S6), the CPU 19
Reads the residual frequency data in the residual frequency data area 3C of the card 2 via the head (step S7). Then, the issuing frequency data in the memory 17 corresponding to the code information correctly read in step S4 is read, and the issuing frequency data in the read memory 17 and the remaining frequency read from the card 2 in step S7 are read. The data is compared with the size (step S8). Here, the frequency data at the time of issue in the memory 17 is stored in the remaining frequency data area 3C of the card 2.
If the data value is larger than the data value in (2) (that is, if "Y" in step S9), the card 2 is determined to be a normal card (step S10), and the call service by the card 2 is permitted.

If the issuing frequency data value in the memory 17 is smaller than the data value in the remaining frequency data area 3C of the card 2 (ie, if "N" in step S9), the remaining frequency It is determined that the data has been illegally rewritten, and it is determined that the card is abnormal (step S11), and the card 2 is immediately returned. Also, the check result of the data in the card identification data area 3A or the check result of the code information in the frequency code area 3B at the time of issuance is not normal,
If “N” is determined in step S3 or step S6, it is similarly determined to be an abnormal card (step S1).
1) Return card 2 immediately.

As described above, the card identification data area 3A in which the date of manufacture and the serial number are recorded at the time of issuance, and the frequency data area in which the frequency data is recorded at the time of issuance and the residual frequency data is recorded at the time of using the card 3C is provided with an issue frequency code area 3B in which code information corresponding to the frequency data at the time of issue is recorded, and the issue frequency data according to the code information is stored in the memory 17 of the public telephone 1. When the card is used, the frequency data at the time of issuance in the memory 17 corresponding to the code information read from the card is compared with the data in the remaining frequency data area 3C of the card to determine whether the service is permitted. It is like that.

As a result, the validity of the card can be accurately determined without increasing the recording capacity of the card. In addition,
In the present embodiment, an example is described in which a card reader that records and reproduces information with respect to the card 2 is applied to a public telephone, but the same applies to other devices that receive services using the card, such as vending machines.
