Abstract

PURPOSE:To prevent the foul use of a magnetic card and to avoid unexpected damage with use of an existing magnetic reading/writing device, by reducing successively the value information written to the magnetic card by means of a heating device in accordance with an amount of transaction. CONSTITUTION:A desired area (m) of a magnetic stripe 2 is divided equally into (n) parts on a base 1 of a magnetic card C which is used to a transaction device. Then the value information equivalent to a unit charge is written previously on each of unit areas E1-En. The card C is put into a slit 4 of a transaction processor, and a card sensor 5 detects the card C. Then the card C is carried to the position of a reading head 12 of the transaction processor by pulleys 8-11 which drive conveyor belts 6 and 7. Then the areas E1-En of the stripe 2 are heated up to temperatures higher than the Curie point by a heating device 13 according to the arithmetic result corresponding to an amount of transaction. Thus the value information written to those unit areas are reduced. The relative positions between the position of the device 13 and each unit area of the stripe 2 are detected by a card end sensor 14. This prevents the generation of the unexpected damage of the transaction.

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 1III information equivalent to a predetermined amount of money is recorded in advance is used for a transaction, a unit fee corresponding to the transaction amount is charged. This relates to a transaction processing device that sequentially reduces the amount collected over time or over time.

For example, in time-rental scale game machines, bus fare collection machines, public telephones, etc., the user must purchase a magnetic card worth a certain amount in advance, and insert the magnetic card into the card slot of the machine before using the machine. By this,
In some cases, the recorded value information is reduced in accordance with the usage time or the number of times of use, and the charge is fu'n.

In such devices, value information initially recorded on a magnetic card is read when the device is activated and stored in a storage device as balance information. Next, as the usage R11 progresses, 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 ends.

However, due to the magnetic i11 exchange means, 1Ir11
Reading the 1t1 information and re-writing it λ may cause unexpected damage to the equipment installation in today's situation where various magnetic cards are flooded.

In other words, the fact that there are so many magnetic cards in circulation 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.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional devices and to provide a magnetic card transaction processing device that cannot be used fraudulently.

An embodiment 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 desired area w1. of the magnetic stripe 2 provided on the base 1. Divide II into n equal parts and divide each unit area [+, E2, Eko, ......, E
Value information corresponding to the unit charge is written in advance in n.

For example, one unit of 1ii11ri is 50 yen, and n is 204
1, the magnetic card C as a whole has a value of 1000 yen.

Next, FIG. 3 shows a schematic diagram of the transaction processing He of the present invention which accepts such a magnetic card C.

The device body 3 includes a card detection sensor 5 that detects that the magnetic card C is inserted through the insertion 04, and a magnetic card C.
A conveyor belt 6.7 that pinches and conveys the
pulley 8.9.10.11 that drives the magnetic card C
Recorded in! Read bet 12 to read li value information
and unit areas E+, E2,... of the magnetic stripe 2.
. . ., a heating device W113. that sequentially heats En to a temperature equal to or higher than the Curie point based on the calculation results. as well as,
At the heating device W113 and each unit fr of the magnetic stripe 2
A card end detection sensor 14 is provided to detect the relative position of the card end. Pulley 9.10 is motor M
(not shown). 15.16.1
7.18 is a guide roller.

The fourth factor is a circuit block diagram for operating the device body 3.

After the power is turned on, when the magnetic card C is inserted from the insertion slot 4, the card detection sensor 5 installed near the pulley 8.11 detects it, and the card detection section 20 outputs its output signal. Ru. As a result, the tIJ 111 section 21 starts the Q ill O operation, and the motor M is driven via the motor drive section 21 . The conveyor belt 6.7 is actuated by the drive of the motor M, and the magnetic card CG and t'JJRe inserted into the insertion slot 4 are taken into the main body 3 by the belt 6.7 and conveyed.

...When the leading end of the card C is detected by the card end detection sensor 14, the card C is moved to a closed area in the first fSIJ area by the reading head 12 and the data reading unit 23 while traveling facing the reading head 12 and the heating device W113. unit li
The i value data is read one after another, and the result is! IIIw
It is sent to the J section 21.

The υ1111 section 21 stores the read data in units lai
In addition to determining whether the value information is *9h,
The data determined to be valid are added and the sum of 5 is accumulated and stored in the value information storage section 25. When the total value stored in the value information storage section 25 is of sufficient value to operate the operating circuit 24, the control circuit 21 operates the operating circuit 24. The ll1 production circuit 24 corresponds to a game console or a telephone communication circuit.

Every time the operation circuit 24 operates for the unit charge, a charge collection signal is output to the 1lIII11 section 21, and the control section 21
Each time it receives this fee collection signal, it subtracts the unit fee from the total value stored in the t1ita information storage section 25. As a result of the reduction, when the remaining amount Z + a I'fi becomes insufficient to operate the operation circuit 24, a stop signal for stopping the operation of the operation circuit 24 is activated by the control 181S.
It is output from 21.

On the other hand, every time the control unit 21 receives a fee collection signal from the operating circuit 24, the unit fI4 area E of the magnetic card C is heated to i=degrees above the Curie point by heating 1ffi13 via the data erasing unit, and the magnetic reread,
Make rewriting impossible.

That is, the data erasing unit 26 is moved around and the heating device 13 is pressed to the position of the predetermined unit area E+ of the magnetic stripe 2,
By heating the tip to a temperature above the -X''-Lee point, the magnetic recording information recorded on the magnetic stripe 2 is erased.

To determine whether magnetic rewriting or rereading has become impossible, drive the motor M while detecting the position of the card using card edge detection f91!22, and apply the heated unit area of the magnetic stripe 2 to the head 12. Contact data reading section 2
Try reading the data using 3. After performing a reread operation and determining that the data cannot be read,
The motor M is driven again to position the magnetic card C so that the next unit area E2 faces the heating device 13. This positioning operation is performed by the card edge detection sensor 1.
4. Card end detection section 22, control I] section 21 and motor M
It is carried out by Thereafter, similar operations are performed every time a toll collection signal is received.

Is the user li? When the use of F is stopped and a stop signal is output from the operating circuit 24, the control unit 21 rotates the motor M in the opposite direction via the motor drive unit 21, and inserts the magnetic card with the deducted amount from the card insertion slot 4. Return C.

Once the magnetic card C has been used in this way,
Only the unit value information that has not been thermally destroyed by the data erasing unit 26 and the heating device 13 indicates the residual value, and it is impossible to rewrite using a magnetic read/write device other than the device according to the present invention. becomes.

In addition, in the above embodiment, a case is described in which a magnetic card C having one magnetic stripe on which value information is recorded in advance is returned by thermally destroying a unit area corresponding to the collected fee on the magnetic stripe. As explained above, two magnetic stripes are provided as shown in Fig. 5, and one magnetic stripe 2a is recorded in an analog manner so that the area of the magnetic stripe is proportional to 1-, and toll collection is carried out thermally. At the same time, the total value information is recorded on the other magnetic stripe regardless of the area of the conventional magnetic stripe, and all remaining value information is digitally re-recorded at the time of toll collection. A self-loading head and a data loading section may be provided to do so. In other words! When reading data from a 1ki card, the tm information is read analogically from one magnetic stripe, and the llI value f! is digitally read from the other magnetic stripe. ! ! If the operating circuit unit 24 is configured to operate only when the information is read and the two match, there is an advantage that unauthorized use is even more difficult in terms of probability.

As explained above, the transaction processing device according to the present invention reduces the value information stored in the magnetic card by sequentially removing it using the heating device according to the transaction amount.
This makes it impossible to use the existing electrical read/write device illegally, and has the effect that there is no unexpected VA damage to the device installation plan.
