Abstract

PURPOSE:To cope with the illegality such as the rewriting of the magnetic information without permission without fail even when a value card used by a card processing device of a high grade machine type to record the remainder information by both a magnetism and a drilled hole is supplied to the card processing device of a lower grade machine type to execute the remainder recording only by the magnetism as it is by providing a permitting means to permit the balancing processing from the remainder information recording on the conditions that the normal decision is executed. CONSTITUTION:On the conditions that the normal decision is executed, the balancing processing from the remainder information recording is permitted. For example, the read magnetic remainder and the calculated drilled hole remainder are compared in size, as the result, as long as the magnetism remainder is smaller than the drilled hole remainder, the normality of the magnetism remainder information is decided, and thereafter, the balancing in a higher order control device 6 is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a card processing device applied to value cards.

(Summary of the Invention) This invention provides a common value for a high-end card processing device that records balances using both magnetism and perforation, and a low-end card processing device that records balances only using magnetism. When using a card, it is possible to deal with fraud such as unauthorized rewriting of magnetically recorded balance information.

(Prior Art and its Problems) Conventionally, this type of cart processing device uses a value card on which balance information is recorded both magnetically and by perforation.

That is, the remaining amount information is magnetically recorded on a magnetic track on the card, and monetary values, such as 0 yen and 100 yen, are written at regular intervals along one side edge of the card.

By printing 200 yen, ... 1000 yen, etc., and punching a hole between adjacent numbers, the current balance is 0 yen to 100 yen, 100 yen to 200 yen, 200 yen to 300 yen, etc. I record whether the price is between 900 yen and 1000 yen.

Here, although the remaining amount information on the magnetic track cannot be visually confirmed, it can be rewritten in either direction, increasing or decreasing.

Further, while the punch-recorded remaining amount information can be visually confirmed at any time, it can only be rewritten to the decreasing side, and cannot be rewritten to the increasing side. This is because the perforations already made must be plugged.

Conventionally, before the payment process, the device confirms whether the magnetically recorded remaining amount information falls within the perforated remaining amount range, and based on the result, the magnetic remaining amount information is We are trying to determine whether it is normal or abnormal.

However, as credit card companies are merging and collaborating in recent years,
A demand has arisen for a single value card to be compatible with low-grade card processing devices, ie, devices that only record balance information magnetically and do not perform perforation recording.

Therefore, if a value card processed by a low-end card processing device is applied to a high-end card processing device and the above-mentioned normality/abnormality determination process is performed on the magnetic balance, the magnetically recorded balance information Since the magnetic balance information does not match the punch-recorded balance information, there is an inconvenience that the magnetic balance information is erroneously determined to be abnormal even though it is normal.

Therefore, it may be possible to omit the matching between the magnetically recorded balance information and the punch-recorded balance information, but in that case, it would be completely defenseless against fraudulent acts such as rewriting the magnetic information without permission. , theft prevention problems remain.

(Object of the Invention) An object of the present invention is to replace the value card used in a high-end model card processing device that records balance information with both magnetism and perforation with a low-grade card processing device that records balance information only with magnetism. It is an object of the present invention to provide a card processing device that can reliably deal with fraud such as unauthorized rewriting of magnetic information even when applied as is to a card processing device.

(Structure and effect of the invention) In order to achieve the above object, the present invention provides a first card that can be rewritten from the inserted value card to either increase or decrease.
a reading means for reading the remaining amount information record and a second remaining amount information record that can be rewritten only on the decreasing side; a comparing means for comparing the first remaining amount information record and the second remaining amount information record; determining means for determining that the first balance information record is normal only when the second balance information record is smaller than the balance information record; The present invention is characterized by comprising: a permission means for permitting payment processing;

According to such a configuration, the first balance information is determined to be normal only when the second balance information is smaller than the first balance information. Even if the first remaining amount information and the second remaining amount information do not match due to the processing, the remaining amount information of the value card will be determined to be normal. If a fraudulent act of rewriting the balance information in 1 without permission is carried out, the fraudster usually rewrites the 1st balance information so that it increases more than the 2nd balance information (i.e., the actual balance). In this case, it is possible to reliably determine that the value card has been illegally rewritten.

(Description of Embodiment) FIG. 1 is a block diagram showing the electrical system configuration of an embodiment of the present invention.

As shown in the figure, this card processing device includes a card processing mechanism 1 and a microcomputer (interface 2.CP
U3. The system is mainly composed of an interface 3 and a memory 4), and is capable of communicating with a host control device 6 that performs actual payment processing and the like.

FIG. 2 is an explanatory diagram showing details of the card processing mechanism 1.

In the same figure, a front panel 101 of the card processing device housing is provided with a card insertion slot 102, behind which an upper conveyor belt 103 and a lower conveyor belt 104 for conveying cards are installed, and entrance sensor rollers 105, 1
06 and the upper and lower terminal ends 107 and 108 respectively.

Upper conveyor belt 103. On the conveyance path where the card is held between the lower conveyor belt 104 and the lower conveyor belt 104, there are inlet sensors 108. Magnetic reading head 109. l
a writing head 110. A drilling mechanism 111 with a drilling solenoid 112. A perforation sensor #j' 113 and a termination sensor 114 are arranged. Note that 115 and 116 are pad rollers.

Then, the pulse motor 118 is connected via the drive belt 1]7.
By driving the lower end roller 108 by
The upper first general conveyance belt 103 and the lower first general conveyance belt 104 can feed the card back and forth while holding the card between them.

Inlet sensor 108. As the terminal end sensor 114, for example, a transmission type photoelectric sensor is used.

FIG. 3 is a flowchart showing the configuration of a control program for the card processing device executed by a microcomputer, and the operation of the device according to the embodiment of the present invention will be systematically explained below with reference to this flowchart.

In Figure 2, the value card 7 is inserted into the card insertion slot '102.
(See Fig. 4) is inserted, this is detected by the entrance sensor 108 (step 301 affirmative), the pulse motor 118 immediately rotates in the forward direction (step 302), and the value card is transferred to the upper and lower conveyor belts 103, 104. It is carried to the back of the equipment while being held between the two.

Then, while passing under the magnetic reading head 109, magnetic information is read from the magnetic track on the card (step 303).

Here, since information indicating the validity of the card is recorded on the magnetic track on the card, if the card is determined to be invalid (No in step 304), the pulse motor is immediately reversely rotated (step 328). The inserted value card is returned to the card insertion slot 102 (steps 324 to 327).

On the other hand, if the card is determined to be valid (Yes at step 304), the card continues to be transported further into the apparatus.

Then, the tip 70 of the card 7 (see FIGS. 4 and 5)
When the pulse reaches the perforation sensor 113 (see step 305), counting of predetermined pulses is started (step 306). This pulse is generated one by one each time the card 7 is conveyed a certain minute distance (
For example, use the drive pulse of a pulse motor or the output pulse of a rotary encoder).

Next, the remaining amount display hole 71 of the card 7 (Figs. 4 and 5)
(see figure) reaches the perforation sensor 113 (step 307tiI), pulse counting stops (step 308), and the remaining amount of perforation is calculated based on the pulse count obtained by subtracting i5% (step 309).

At this time, the value of the pulse count is the distance from the tip 70 of the card 7 to the perforation 71, as shown in FIG. It corresponds to this distance on the card side! It is set in advance so that the remaining amount on the card is not displayed. Therefore, by comparing the pulse count number with each scale numerical value range 72, the remaining amount information recorded by punching can be calculated.

Next, a balance normality/abnormality determination process according to the present invention is performed (step 310). That is, step 303
The magnetic residual amount read in step 309 and the punched residual amount calculated in step 309 are compared in size, and only when the magnetic residual amount is smaller than the punched residual amount, the residual amount is determined to be normal.

Here, if the magnetic residual amount is larger than the punched residual amount due to an unauthorized rewriting process being performed on the magnetic residual amount (step 310, negative), the magnetic residual amount is determined to be abnormal, and the magnetic residual amount is immediately pulsed. The motor is reversed (step 32).
8) The inserted card is returned to the card insertion slot 102 (Stellar 1324 to Step 327).

On the other hand, if the magnetic residual amount is smaller than the drilling residual amount (
Step 310 (Yes), the magnetic balance is determined to be normal, and the card continues to be transported further into the device.

When the leading end 7o of the card 7 reaches the terminal end sensor 114 (Yes at step 311), the pulse motor stops (step 312).

In this way, if the magnetic balance read from the magnetic track of the card is determined to be normal, settlement from the magnetic balance is permitted, and the obtained magnetic balance information is sent to the host controller 6. This is used for settlement processing on the higher level control device 6 side (step 313).

Thereafter, the host controller 6 waits for the payment to be completed and new balance information to be sent (step 314).
).

When new balance information is received from the host controller 6 (Yes at step 314), the pulse motor 118 is rotated in the opposite direction (step 315) to transport a portion of the money back toward the entrance.

Next, when the rear end of the card 7 (see FIG. 4) reaches the perforation sensor 113 (step 316 affirmative), counting of unit distance conveyance pulses is started again (step 31).
7).

Then, the pulse counting from the rear end of the card to the punching position corresponding to the new balance amount is completed.Step 3
18 affirmative), pulse counting is stopped and (
Step 319), the pulse motor is also stopped (Step 320), and the drilling solenoid is driven to drill a hole in the middle of the scale value corresponding to the new balance (Step 32).
1).

When the punch recording is completed in this manner, the pulse motor is reversely rotated again (step 322), and the card is roughly conveyed toward the entrance direction, and while passing under the magnetic write head 110, the new balance information is recorded. A magnetic write process is performed (step 323).

Then, when the rear end of the card reaches the entrance sensor 108 while the card is being roughly conveyed (step 324 affirmative), a predetermined minute timer is started (step 325), and the timer is waited for. (Step 32
6 (affirmative), the pulse motor should stop (step 327)
, the conveyance ends with the card partially protruding from the card insertion slot 102.

As described above, in this embodiment, the magnetic residual amount read in step 303 and the drilling residual amount calculated in step 309 are compared in size, and only when the magnetic residual amount is smaller than the drilling residual amount, the corresponding After determining whether the magnetic balance information is normal, the host controller 6 is then allowed to perform payment.

For this reason, as shown in FIGS. 4(a) to 4(d), for example, a ticket vending machine with a perforation mechanism (high-end model) and a can use vending machine without a perforation mechanism (low-class model) have a common value card 7. Even if there is a discrepancy between the perforation residual amount and the magnetic residual amount as shown in (b) and (c) in the same figure due to the use of the As a result, it will no longer be erroneously determined that something is abnormal even though it is normal.

On the other hand, as mentioned above, it is natural for a fraudster who rewrites the magnetic balance without permission to rewrite the magnetic balance so that the magnetic balance becomes larger than the punched balance (actual balance). Therefore, the value card that has been subjected to the unauthorized rewriting process is determined to be abnormal in the determination process of step 310, and settlement permission is never granted for such an unauthorized value card.

In other words, it becomes possible to use a common value card with a ticket vending machine that has a perforation mechanism and a can reuse vending machine that does not have a perforation mechanism, and the magnetic balance of the value card cannot be changed without permission. In such a case, this can be immediately determined and theft prevention can be ensured.

In the above embodiment, magnetic recording is used as the first balance information record that can be rewritten to either the increase or decrease side, and a perforated record is used as the second balance information record that can be rewritten only to the decrease side. As explained above, the first balance information record may be a semiconductor record like an IC card, and the second balance information record may be a stamp mark using ink that is hard to erase. be.
