Abstract

PURPOSE:To prevent a magnetic card from illegal use by destroying approximate value information written in the 2nd magnetic stripe of the card successively and magnetically in accordance with the transaction amount and comparing the left information with that written in the 1st magnetic stripe. CONSTITUTION:In the magnetic card C, the approximate value area of the 2nd magnetic stripe 3 is successively destroyed so as to be disabled to be reread and rewritten by punching or the like every use of it. Whether the card is a real magnetic card or not is decided by checking that the 1st inherent information ID2a recorded on the 1st magnetic stripe 2 on the magnetic card C coincides with the 2nd inherent information left without being destroyed out of plural information recorded on the 2nd magnetic stripe 3 at a fixed interval and both the stripes are on the same magnetic card. In addition, whether an illegality exists or not between the variable value information indicating the balance of the value area 2b of the 1st magnetic stripe 2 which is rewritten in accordance with the transaction amount and the approximate value information of the 2nd magnetic stripe 3 is discriminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a transaction processing device using a magnetic card, particularly when a magnetic card on which value information equivalent to a predetermined amount is recorded in advance is used for a transaction, a unit fee corresponding to the transaction amount is processed by time or This relates to a transaction processing device that sequentially collects a reduced amount as the number of transactions increases.

For example, in time-based game machines and public telephones, users purchase magnetic cards worth a certain amount of money in advance, and insert the magnetic card into the card slot of the device to determine the amount of time they can use the device. In some cases, the recorded value information is reduced according to the amount, and the fee is settled.

In such a device, the value information initially recorded on the magnetic card is read when the device is operated and recorded in the recording device as balance information. Next, as the usage time elapses, the amount corresponding to the unit charge is gradually reduced, and in many cases, the balance information is magnetically recorded on the magnetic card again and returned when the usage is finished. However, reading and rewriting value information using magnetic rewriting means may cause unforeseen damage to the person installing the device, given the proliferation of various magnetic cards available today.

In other words, the fact that there are various types of magnetic cards on the market means that there is a high risk that the information recorded on the magnetic card could be read and rewritten by a device other than that device. This is because it becomes possible to record the same contents as an unused magnetic card. In particular, if a device for reading and writing magnetic cards is stolen, it is easy to write the same recorded contents on a used magnetic card as on an unused magnetic card.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic card transaction processing device that eliminates the drawbacks of the conventional devices and prevents unauthorized use.

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a magnetic card used in the device of the present invention.

The magnetic card C has a first magnetic stripe 2 and a second magnetic stripe 3 provided on a base 1.

The magnetic card C shown in the figure has been used several times by the user after purchase, and there are two holes 4a and 4b on the second stripe 3.
is open.

Like the magnetic stripe of a conventional magnetic card, the first magnetic stripe 2 has a first unique information ID unique to the card, such as card issuer, issue number, card identification number, etc., recorded in the ID area 2a. , in another area, that is, the value area 2b, variable value information M indicating the monetary value for the transaction is recorded. In the case of this magnetic card C, since it has been used several times, the monetary value at the time of purchase is reduced by an amount equivalent to the amount collected in the transaction, and the remaining amount is rewritten into corresponding value information.

As shown in FIG. 2, the second magnetic stripe 3 has a card-specific number corresponding to at least a part of the first unique information already written in the ID area 2a of the first magnetic stripe 2 at the time of purchase. 2 unique information idl, id2, ida, --

m2, ..., m5 are recorded respectively, and when the user uses this magnetic card for 35 units, that is, the equivalent of 350 yen, the first magnetic stripe 2 is recorded as shown in Figure 1. The value area 2b is rewritten to show value information equivalent to the remaining amount of 650 yen, and the second magnetic stripe 3
Approximate value area 3b +, 3b 2 has a hole 4a
, 4b are perforated, and the perforated area cannot be magnetically rewritten or reread, leaving an approximate value (a).
Only area 3b3.3b4.3b5 can be reread.

In addition, an indication printed along the magnetic stripe 3 in the vicinity of the second magnetic stripe 3 of the magnetic card C and a hole punched on the second magnetic stripe 3 make it easier to use the card. This allows a person to visually read the approximate 1Ili value information of the card.

Specifically, in the example of FIG. 1, the second ID area 3a 1.3a of the second magnetic stripe 3 of the magnetic card C
2.3a 3N..., next to 3as, the numbers 100, 80, 60, 40, 20, O are printed on the card C, and the second magnetic stripe 3 Hole 4a in rough value area 3b+, 3bz
, 4b are punched, so the user sees this and determines that the value of at least 60 units, that is, 600 yen, remains on the card C.

It runs opposite 5.

The information recorded on the first magnetic stripe 2 on the magnetic card C is read by the first read/write head 14 and the first data reader 22, and the information recorded on the second magnetic stripe 3 is read by the first read/write head 14 and the first data reader 22. , second read head 14

By cutting the gap between the magnetic stripe 3 and the second magnetic stripe 3, it is possible to prevent the card from being used in combination with the magnetic stripe of another magnetic card.

On the other hand, variable value information M and approximate value information ll111m2, ll13, . . . , m n − are read simultaneously.
+ is also compared and determined by the determining means 24. That is,
Rough value area 3bl that can be read as rough value information
, 3b2.3b3, ..., 3bn-+ on the second magnetic stripe 3 and the readable number, it is possible to know the approximate residual value of this magnetic card C as described above. .

As the number of approximate value areas increases, it is possible to indicate a value closer to the true residual value, but the length of the magnetic stripe is divided into equal parts as appropriate in relation to positional errors when erasing without re-reading or re-writing. It is desirable to provide a

The comparison is made based on whether there is any unreasonable point between the value indicated by the variable value information and the value indicated by the approximate value area. In this way, the first magnetic stripe 2
If the indicated value is within the value indicated by the second magnetic stripe 3, then a transaction is possible.
Even if an existing magnetic recording device is used to rewrite the first magnetic stripe 2 and a used magnetic card is rewritten with the same information as an unused magnetic card, the device can be used by the determining means 24. Since no signal is output, unauthorized use is impossible.

When the determination means 24 outputs a determination signal indicating that the data is not fraudulently used, the control section 25 stores the read data in the value information storage section 26 .

The value stored in the value information storage section 26 is stored in the operation circuit 27.
When the value is sufficient to activate the controller 25, the control unit 25 activates the operating circuit 27. The operating circuit 27 corresponds to a gaming machine main body or a communication circuit.

Each time the operation circuit 27 performs an operation corresponding to the unit charge, a charge collection signal is output to the control section 25, and each time the control section 25 receives this charge collection signal, it outputs the value stored in the value information storage section 26. The unit fee will be reduced from As a result of the reduction, when the remaining value becomes insufficient to operate the operation circuit 27, a stop signal for stopping the operation of the operation circuit 27 is output from the control unit 25.

On the other hand, the value stored in the value information storage unit 26, which has been reduced by receiving the fee collection signal from the operating circuit 27, is changed to each approximate value area 3b1.3b2.3b3, . . . , 31+
n-+ (in the above example, the range of 99 units to 80 units, the range of 79 units to 60 units, the range of 59 units to 40 units,

6 and the output of the motor drive unit 21 are detected by the card position detection unit 29 which measures the card position, and then the motor MT is driven to move the second reading head 14'' over the second magnetic stripe 3 again. data reading section 2.
Read and confirm the data in step 3. This positioning is performed by the card end detection sensor 16 and the card position detection section 29. Thereafter, similar operations are performed every time a toll collection signal is received.

When the user stops using the device and a stop signal is output from the operation circuit 27, the control unit 25 transfers the value stored in the value information storage unit 26 to the first data rewriting unit 30 and the first read/write unit. The value area 2b of the first magnetic stripe 2 is written by the head 14. When writing is completed, the motor MT is rotated in the opposite direction via the motor drive unit 21,
The magnetic card C with the reduced amount is returned from the card insertion slot 6. In this way, each time the magnetic card C is used, the approximate value areas 3bl, 3b2,
. . ., 311n-+ is sequentially rereadable and unrewritably destroyed, and only the remaining undestructed approximate value area and second ID area are rereadable, and the first magnetic field that is read at the same time Since whether the card is a genuine card or not and the true remaining value is indicated only by checking the information on stripe 2, it becomes impossible to use the card fraudulently using a magnetic reading/writing device other than the device according to the present invention.

In the above embodiment, a case has been described in which drilling is performed as a method of destroying the approximate value area of the second magnetic stripe 3. The magnetism may be extinguished by pressing the J-shaped boss so that it protrudes in the direction away from '.

Moreover, the second ID area on the second magnetic stripe is not provided alternately with the approximate value area, but is provided on the - right side and the other side.
It may be set up separately.

When reading data from a magnetic card, one of the
Accurate value information and ID information are read from the magnetic stripe, and approximate value information and FD information are read from the other magnetic stripe 1, and the operating circuit section 27 operates only when the two match. It should be configured as follows.

As explained above, the transaction processing device according to the present invention has a second
The approximate value information written on the magnetic stripe is magnetically destroyed in order according to the transaction amount, and the information written on the second magnetic stripe and the information written on the first magnetic stripe are destroyed. The device compares the stored information to determine whether it is a legitimate magnetic card and then allows the device to be used, so it is impossible to use existing magnetic reading/writing devices illegally. This has the effect of preventing unexpected damage to the person installing the equipment.
