Description

Description: TECHNICAL FIELD The present invention relates to a data processing device for performing a transaction using a postpay card that can be used multiple times.

[Related Art] In recent years, for example, postpay cards for taxis and the like have been developed as recording media for paying ride fares.
This post-pay card reads recorded data, and if the data satisfies predetermined conditions, the fee can be postpaid.For example, if a sales department employee uses a taxi for company use, It is paid by the company, and the company pays for the taxi used by employees later. By the way, since the usage limit of postpay cards is fixed, if the transportation expenses such as taxi fare are inevitably high, it is dealt with by giving a plurality of postpay cards to the employees. That is, in one ride, a plurality of post-pay cards are sequentially read, and a fee up to the total usage limit can be paid.

[Problems to be Solved by the Invention] However, since payment can be made using a number of post-pay cards, the same post-pay card (recording medium) is used many times, and a taxi fare exceeding the usage limit is used. It is possible to pay fraud. Therefore, in the same transaction, there is a possibility that a payment exceeding the usage limit is made using the same recording medium.

An object of the present invention is to prevent the same recording medium from being used more than once in the same transaction.

[Means for Solving the Problems] The means of the present invention are as follows.

The reading means reads the identification data recorded on the recording medium in the transaction processing.

The storage means stores the identification data read by the reading means.

The erasing means erases the identification data stored in the storage means at the end of the transaction.

The transaction processing means, when the identification data of the recording medium is read again by the reading means during the transaction, when the identification data is different from the identification data already stored in the storage means. , A transaction process based on this recording medium is performed.

If the identification data read again from the recording medium during the transaction is the same identification data as the identification data already stored in the storage means, the transaction processing based on the recording medium is prohibited. .

[Operation] The operation of the means of the present invention is as follows.

In the transaction processing, the reading means reads the identification data recorded on the recording medium, and the read identification data is stored in the storage means, but the stored identification data is erased by the erasing means at the end of the transaction. Is done. Then, when the identification data of the recording medium is read again by the reading means during the transaction, if the identification data is different from the identification data already stored in the storage means, A transaction based on the recording medium is performed by the transaction processing means. If the identification data read again from the recording medium during the transaction is the same identification data as the identification data already stored in the storage means, the transaction processing based on the recording medium is prohibited. You.

Therefore, it is possible to prevent the same recording medium from being used more than once in the same transaction.

Embodiment An embodiment will be described below with reference to the drawings shown in FIGS. The data processing device in this embodiment includes a card reader / writer capable of processing postpaid cards and prepaid cards, and is mounted on a taxi.

FIG. 1 is a block diagram showing a circuit configuration of a data processing device. In the figure, the key input unit 11 is “0” to

d, a "cancel" key 11e for instructing cancellation of the transaction, and other keys. When a key is input, the key input unit 11 outputs a key input signal corresponding to the key input to the CPU 12.
Output to

The CPU 12 executes various processes such as a registration process and a taxi fee withdrawal process according to a key input signal output from the key input unit 11. These various processes are executed based on a control program stored in the ROM 14 described below in advance.

The RAM 13 stores various data, and the reading / writing is controlled by the CPU 12. As shown in FIG. 1, the RAM 13 includes a negative file, a transaction negative file, an operation data file, a billing data file, and a card data file. In this case, the negative file is a memory area for storing a defective customer ID number, a lost card ID number, and the like. The transaction negative file is a memory area in which the ID number of the postpay card used in the same transaction is stored. The operation data file contains mileage, time,
This is a memory area for storing operation data such as fares and area codes. The billing data file is a memory area that stores taxi billing billing data for each postpay card ID number. The card data file is a memory area in which card data such as an ID number read from a post pay card is stored. The RAM 13 also has an unsettled amount register (not shown) for storing unsettled amount data.

A card R / W (reader / writer) 15 is connectable to, for example, a postpaid card or a prepaid card constituted by a magnetic card, and has a magnetic head for reading or writing data recorded on each card, a card transport mechanism, and the like. Is built-in. In this case, the post-pay card contains the card type, ID number, limit of use, number of uses,
Card data such as the maximum number of use times is recorded.

Clock 16 measures the current time and stores the current time data in CPU1.
Output to 2. The display unit 17 includes, for example, a fluorescent display panel, and displays price data such as a taxi fare based on display data output from the CPU 12. The printer 18 performs printing based on the print data output from the CPU 12, and issues a form such as a receipt. The buzzer 19 generates an alarm sound for an error or the like. I / F (interface) 2
“0” performs data transfer between the CPU 12 and the meter 21. Meter 21
Is a taxi meter that measures the traveling distance according to the rotation of the wheels and outputs traveling distance data to the CPU 12 via the I / F 20. The meter 21 has a “running” position and an “empty” position.

Next, the operation of the above embodiment will be described based on the flowchart of FIG. In this case, when the taxi carries a customer and the meter 21 is returned from the "running" position to the "vacant" position, the processing in FIG. 2 is started.

First, a registration process is performed in step S1. This registration process is a process of storing operation data such as mileage, time, taxi fare, and area code in an operation data file of the RAM 13 and storing taxi fare amount data in an unsettled amount register.

In step S2, the transaction negative file in the RAM 13 is cleared, and the ID of the post-pay card used in the previous transaction is cleared.
The number is cleared.

In step S3, the postpay card is
It is determined whether it has been inserted into W15. This step S3
If YES is determined in step S4, the process proceeds to step S4, and if NO, the process proceeds to step S23.

In step S4, the card data recorded on the postpay card, that is, the card type, ID number, usage limit, usage count, usage limit count, and the like are read from the postpay card.

In step S5, the read card data is
It is stored in the card data file in M13.

In step S6, it is determined whether the negative file check is OK. That is, the data stored in the card data file
It is determined whether the ID number matches the bad customer ID number or the lost card ID number stored in the negative file in the RAM 13. If it is determined to be OK in step S6, the process proceeds to step S7. If it is determined as NG in step S6, the card is defective or lost, and the process proceeds to step S25 to discharge the post-pay card out of the apparatus.

In step S7, the negative file check in the transaction
It is determined whether or not it is OK. That is, the ID number stored in the card data file is the ID stored in the transaction negative file.
It is determined whether the numbers match. In this step S7
When it is determined to be OK, the process proceeds to step S8, and when it is NG, the process proceeds to step S25.

In step S8, it is determined whether or not the use count check is OK. That is, it is determined whether or not the usage count data read from the post pay card matches the usage limit count data. If it is determined to be OK in step S8, the process proceeds to step S9. If it is NG, the process proceeds to step S25 because the usage limit has been exceeded.

In step S9, it is determined whether or not the unsettled amount data stored in the unsettled amount register is larger than the usage limit read from the postpay card. If YES is determined in step S9, the process proceeds to step S10, and if NO, the process proceeds to step S18.

If the unsettled amount data is larger than the usage limit, the process proceeds to step S10, where the usage limit is written to the billing data file in the RAM 13 corresponding to the ID number. In the following step S11, the usage limit is subtracted from the content of the unsettled amount (unsettled amount data), and the subtraction result is written in the unsettled amount register. In step S12, the ID number stored in the card data file is registered in the transaction negative file in the RAM 13. Next, in step S13, the usage count data read from the post-pay card and stored in the card data file is incremented by one. In step S14, the data of the number of times of use counted up is written to the post pay card.

In step S15, it is determined whether the unsettled amount is “0”, that is, whether the contents of the unsettled amount register is “0”. If YES is determined in this step S15, the process proceeds to step S16, and if NO, the process proceeds to step S20. In step S16, since the settlement is completed, the post-pay card inserted in the card R / W 15 is discharged out of the apparatus. At step S17, receipt printing is performed, and the process returns to the registration waiting state.

If NO is determined in the step S15, a sign indicating that partial payment is being made is displayed in a step S20. Therefore, the taxi user pays the unsettled amount (balance) by cash or a prepaid card. Next, in step S21, the post-pay card inserted in the card R / W 15 is ejected out of the apparatus. Proceeding to step S22, receipt printing is performed. After executing step S22, the process returns to step S3.

When step S3 is executed again, since the post-pay card has been ejected, the determination becomes NO, and the process proceeds to step S23.
In step S23, other payment processing, that is, payment processing using cash or a prepaid card is executed. In the following step S24, the content of the unsettled amount register is “0”
Is determined. In this case, a settlement process using cash or a prepaid card is executed, and if the unsettled amount data becomes “0”, YES is determined in the step S24, and a registration wait state is set. Further, the settlement processing by cash or prepaid card is not executed, and if the unsettled amount data is not “0”, NO is determined in the step S24 and the process returns to the step S3.
Hereinafter, steps S3, S23, and S24 are repeatedly executed until “unsettled amount = 0” and YES is determined in step S24.

At this time, a case will be described in which a post pay card is inserted into the card R / W 15 in order to use the post pay card again in the same transaction. As a result, the answer is YES in step S3, and the process proceeds to step S4, in which the card data recorded on the re-inserted post-pay card is read. In step S5, the read card data is stored in the card data file, and the process proceeds to steps S6 and S7.

In step S7, it is determined whether the intra-transaction negative file check is OK as described above. In this case, since the ID number stored in the card data file matches the ID number stored in the transaction negative file, it is determined to be NG and the process proceeds to step S25, where the inserted post-pay card is discharged out of the device. Is done. Therefore, it is possible to prevent the post-pay card from being used again in the same transaction.

If the unsettled amount data is equal to or less than the usage limit in step S9, the process proceeds to step S18, and the contents of the unsettled amount register are written to the billing data file of the RAM 13 corresponding to the ID number. Next, in step S19, "0" is written to the unsettled amount register to clear it, and the process proceeds to step S12. Hereinafter, steps S12, S13, S14, and S15 are executed as described above, and YES is determined in step S15, and the process proceeds to steps S16 and S17.

[Effects of the Invention] According to the present invention, the same recording medium can be prevented from being used more than once in the same transaction. It is possible to prevent fraudulent payments.
