Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is a system for supporting a transaction, in which a transaction is performed using a debit card system.
[0002]
[Prior art]
In a game shop such as a pachinko parlor, a pachinko patron may purchase a prepaid card that can be exchanged for a pachinko ball using a debit card system.
[0003]
The debit card system that uses this debit card to settle transactions can be used as a cash card that you can carry on a daily basis as a card that can be settled on the spot. There is an advantage that the purchase of goods and the provision of services can be received by a cash card of a bank or the like, and that shopping can be performed with confidence within the range of the deposit balance.
[0004]
In addition, merchants have the advantage of being able to collect money reliably and efficiently and to facilitate customer management. In addition, financial institutions have the advantage that they can find new customers smoothly and earn commission income.
[0005]
Therefore, if the service is provided using such a debit card, the user can receive a cash card that is usually carried around, for example, lending game media at a pachinko parlor, which is very convenient.
[0006]
However, if you allow a pachinko parlor using a debit card to provide a game media lending service without any restrictions, it is a purchase within the player's own funds, but if you are absorbed in the game, you will use up your entire deposit Sometimes, due to social wisdom, a player may use his or her own deposit amount up to an unusual amount to use at a game store.
[0007]
In order to prevent such a situation, transactions from gaming arcades and non-gaming arcades are distinguished, and only transactions made from a debit card processing terminal installed in a gaming arcade are subject to regulation. I am trying to do it. (For example, see Patent Document 1)
[0008]
[Patent Document 1]
JP-A-2002-889 (FIG. 1)
[0009]
[Problems to be solved by the invention]
However, according to the invention described in Patent Literature 1, when the number of stores introducing a debit card system in an amusement store increases and the number of customers per day increases, the processing center of the debit card system has a very large processing capacity. This leads to an increase in processing time and equipment costs, which is not appropriate.
[0010]
The present invention has been developed to solve such inconveniences, and has as its object to provide a system that can appropriately perform debit card transactions.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a representative invention as a solution of the transaction processing system in the present application is a transaction processing system in which a prepaid card usable at a game store can be purchased with a debit card. And a debit card processing unit for performing a prepaid card transaction process based on the settlement by the debit card system, and a gaming machine connected to the debit card processing unit and exchanged with a game medium that can be used in a gaming machine arranged in a game store. A prepaid card providing unit that provides a possible prepaid card and outputs information related to the purchase of the prepaid card, and information connected to the prepaid card providing unit, converted by the debit card processing unit, and information related to the purchase of the prepaid card. Accept and prepaid And a debit card transaction control unit for controlling the provision of the card.The transaction control unit further has a regulation information storage unit for storing predetermined regulation information that can be transacted with the debit card, and is converted by the debit card processing unit. Based on the information and the information on the purchase of the prepaid card, and accumulated information of the transaction based on the information converted in the debit card processing unit, compare the information with the information stored in the regulation information storage unit, It has a transaction judging unit for controlling provision of a prepaid card.
[0012]
The information converted by the debit card processing unit is debit card information read from the debit card and converted by a predetermined encryption algorithm, and the transaction determination unit determines the accumulated amount information and the purchase of the prepaid card. If the sum of the money amount information is within the range of predetermined money information that can be traded with the debit card stored in the regulation information storage unit, the provision of the prepaid card to the prepaid card providing unit is permitted, and the predetermined money If the information exceeds the range, the provision of the prepaid card to the prepaid card providing unit may be refused.
[0013]
The information for decrypting the encryption of the predetermined encryption algorithm may be handled and managed only by the debit card processing unit.
[0014]
With this configuration, the transaction control can be performed by the prepaid card control device, so that the debit card processing center does not need to prepare hardware having a very large processing capability. In addition, it can be assumed that the number of accounts of the converted cash card to be recorded by the prepaid card control device is about 1,000 even if the number is estimated to be large. It is considered that there is almost no burden even if the prepaid card control device is provided with such a data amount.
[0015]
Furthermore, since regulations can be regulated on a store-by-store basis rather than on a debit card processing terminal basis, regulation information can be regulated at stores where multiple debit card processing terminals are installed, or by replacing terminals when the debit card processing terminal fails. Can be cleared.
[0016]
When communicating with the debit card processing center, the debit card processing terminal normally uses encryption algorithms FEAL, DES, RC6, RSA, etc., which have a certain evaluation. The subsequent value is a function that has a bijective relationship, and the encryption algorithm and encryption key used are not disclosed in the prepaid card issuing machine or the prepaid card control device. There is no need to prepare a special data conversion process for the debit card processing terminal to transmit the cash card data to the prepaid card issuing machine or the prepaid card control device.
[0017]
Therefore, the prepaid card control device has cash card data encrypted with these encryption algorithms, but has no means for decryption, and cannot be used for purposes other than debit card transaction control.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a transaction processing system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram related to a transaction processing system according to an embodiment of the present invention. The transaction processing system according to the present embodiment includes a debit card processing terminal 3, a prepaid card issuing machine 4, a prepaid card control device 5, a prepaid card ball lending machine 6, and a ticket issuing unit 7.
[0019]
A transaction processing system is prepared for each store, and FIG. 1 shows a transaction system 1 for the A store and a transaction system 2 for the B store. Note that the transaction processing system of the present embodiment can be configured as a transaction processing system for a plurality of A stores and B stores as described above, in addition to a case where only one store is targeted.
[0020]
The debit card processing terminal 3 is a processing terminal that accepts a debit card, reads out information stored in the debit card, and performs transaction processing of a prepaid card that can be used in a game arcade based on settlement by a debit card system.
[0021]
The prepaid card issuing machine 4 is connected to the debit card processing unit, provides a prepaid card, and outputs information relating to the purchase of the prepaid card. Here, the prepaid card is an information storage medium that stores information that can be exchanged with a game medium that can be used in a game device arranged in a game store.
[0022]
The prepaid card control device 5 is a control device that is connected to the prepaid card providing unit, receives the information converted by the debit card processing unit and the information regarding the purchase of the prepaid card, and controls the provision of the prepaid card.
[0023]
The prepaid card ball lending machine 6 is a ball lending machine that lends a game medium when a prepaid card is inserted. Note that the debit card processing terminal 3 and the prepaid card ticketing machine 4 may be integrally configured as a ticketing unit 7.
[0024]
The debit card processing center 8 is a processing center that relays transaction processing between the debit card processing terminal 3 and the bank centers A to C. Each of the A bank center 9 to the C bank center 11 confirms whether or not the transaction permission is obtained based on the request of the debit card processing terminal 3, and returns the fact to the debit card processing terminal 3. In this case, depending on the type of cash card used by the player, the A bank center 9 to the C bank center 11 determine whether or not to issue a transaction permit based on the information such as the balance of the selected account. Done.
[0025]
The prepaid card center 12 sets and changes debit card transaction regulation information for each store such as A store and B store based on the information sent from the center terminal 13. When there is a change in the transaction regulation information to the prepaid card center 12, the center terminal 13 transmits the changed regulation information.
[0026]
Hereinafter, processing of the entire transaction processing system of the present invention will be described. The prepaid card center 12 is configured so that the center terminal 13 can set and change the debit card transaction regulation information for each store. Then, the debit card transaction regulation information set in the prepaid card center 12 is distributed to the prepaid card control device 5 corresponding to the store.
[0027]
The prepaid card control device 5 installed in each store stores the debit card transaction regulation information received from the prepaid card center 12. In this way, the debit card transaction regulation information is stored in the transaction processing system of each store and transaction processing is performed.
[0028]
Then, the player inserts a debit card such as a cash card into the debit card processing terminal 3, inputs a password, and specifies the amount of the prepaid card to be purchased. The debit card processing terminal 3 performs data conversion of the cash card data in a manner not known to the prepaid card issuing machine 4 and the prepaid card control device 5. The data conversion method uses a function in which the value before conversion and the value after conversion have a bijective relationship. Further, since a method in which data before conversion cannot be estimated from a value after conversion is preferable, it is preferable to use a cryptographic algorithm having a certain evaluation, such as FEAL, DES, RC6, and RSA.
[0029]
The debit card processing terminal 3 transmits the converted cash card data and the amount of the prepaid card that the player wants to purchase to the prepaid card issuing machine 4. The prepaid card issuing machine 4 which has received this data inquires the prepaid card control device 5 whether or not to issue a ticket. The converted cash card data and transaction data received from the debit card processing terminal 3 are added to this inquiry. Then, the prepaid card control device 5 receiving this inquiry adds the following check in addition to the conventional check.
[0030]
That is, it is searched whether the converted cash card data is used on the same business day. If there is no converted cash card data on the same business day, it is determined whether the transaction is within the range set in the debit transaction regulation information. I do.
[0031]
The prepaid card issuing machine 4 that has received the ticketing permission notification notifies the debit card processing terminal 3 of the transaction permission, and the debit card processing terminal 3 makes a transaction request to the debit card processing center 8. Then, the debit card processing center 8 relays transaction processing between the debit card processing terminal 3 and the bank centers A to C.
[0032]
When a transaction permission is obtained from a predetermined bank center based on the request of the debit card processing terminal 3, the fact is returned to the debit card processing terminal 3. The debit card processing terminal 3 that has received the transaction permission from the debit card processing center 8 outputs a transaction completion receipt and also notifies the prepaid card issuing machine 4 of that fact.
[0033]
The prepaid card issuing machine 4 which has received the notification of the transaction completion from the debit card processing terminal 3 issues a prepaid card and notifies the prepaid card control device 5 of the completion of the issuance of the ticket. Then, the prepaid card control device 5 receiving the ticketing completion newly stores the converted cash card data and transaction information.
[0034]
If the transaction is out of the range set in the debit transaction regulation information, the prepaid card issuing machine 4 is notified of the transaction regulation over. In this case, the prepaid card issuing machine 4 that has received the transaction regulation over notifies the debit card processing terminal 3 of the transaction regulation over. The debit processing terminal displays a message stating that “today's debit cannot be used at our shop due to the transaction limit being exceeded”.
[0035]
In the above case, if there is cash card data converted on the same business day, the current transaction information is added to the corresponding transaction information. Then, it is determined whether the transaction information is within the regulation information.
[0036]
If it is within the regulation information, the same processing as the above processing is performed. Note that the prepaid card control device 5 that has received the ticketing completion adds and updates the transaction information this time to the transaction information corresponding to the converted cash card data. If the information is outside the regulation information range, the prepaid card issuing machine 4 is notified of the transaction regulation over. In this case, the prepaid card issuing machine 4 that has received the transaction regulation over notifies the debit card processing terminal 3 of the transaction regulation over. The debit processing terminal displays a message stating that “today's debit cannot be used at our shop due to the transaction limit being exceeded”.
[0037]
With this configuration, the transaction control can be performed by the prepaid card control device 5, so that the debit card processing center 8 does not need to prepare hardware having a very large processing capacity. In addition, it can be assumed that the number of accounts of the converted cash card to be recorded by the prepaid card control device 5 is about 1,000 even if the number is estimated at most. It is considered that there is almost no burden even if the data amount is provided to the prepaid card control device 5 to this extent.
[0038]
Furthermore, since regulation can be performed not at the unit of the debit card processing terminal 3 but at the store level, regulation at a store where a plurality of debit card processing terminals 3 are installed or terminal replacement at the time of failure of the debit card processing terminal 3 can be performed. Can clear the problem that the regulation information is released.
[0039]
When communicating with the debit card processing center 8, the normal debit card processing terminal 3 uses encryption algorithms FEAL, DES, RC6, RSA, etc., which have a certain evaluation. And the value after conversion is a function of a bijective relationship, and the encryption algorithm and encryption key used are not disclosed in the prepaid card issuing machine 4 or the prepaid card control device 5. It is not necessary to prepare a special data conversion process for the debit card processing terminal 3 to transmit the cash card data to the prepaid card issuing machine 4 or the prepaid card control device 5.
[0040]
Therefore, although the prepaid card control device 5 has cash card data encrypted by these encryption algorithms, there is no means for decryption, and the prepaid card control device 5 cannot be used for purposes other than debit card transaction regulation.
[0041]
FIG. 2 is a diagram showing transmission of information among the debit card processing terminal 3, the prepaid card issuing machine 4, and the prepaid card control device 5 shown in FIG. First, the debit card processing terminal 3 accepts the input of the cash card 20 and the password. Then, the debit card processing terminal 3 converts the information (B) such as a bank account number stored in the cash card 20 into information (B ′) converted by encryption processing using a predetermined algorithm. .
[0042]
The converted information (B ′) and the price button (for example, 1000 yen) of the prepaid card that the player wants to purchase is pressed, and the debit card processing terminal 3 transmits the information to the prepaid card issuing machine 4 as transaction data. I do.
[0043]
When receiving the converted information (B ′) and the transaction data (1000 yen), the prepaid card issuing machine 4 creates a ticketing inquiry 23. Then, the ticketing inquiry 23, the converted cash card data 24 and the transaction data 25 are transmitted to the prepaid card control device 5.
[0044]
Upon receiving the ticketing inquiry 23, the converted cash card data 24 and the transaction data 25, the prepaid card control device 5 stores them in the database 27. The database 27 stores the information converted for each cash card 20 and the transaction accumulation information for today.
[0045]
That is, in the database 27, transaction accumulation information for today is stored for each converted cash card data 24 of each cash card 20 used on the same business day. Then, information on which cash card is used today is stored.
[0046]
For example, in this drawing, converted information (A ′) to (D ′) are stored. Then, for example, it is displayed that the converted information (A ') is already traded for 3,000 yen as the transaction accumulated information for today. The converted information (B ′) indicates that 5,000 yen has already been traded as the transaction accumulation information for today. The converted information (C ') indicates that 30,000 yen has already been traded as today's transaction accumulation information. The converted information (D ') indicates that 10,000 yen has already been traded as the transaction accumulation information for today.
[0047]
As described above, information is stored in the database 27 for each converted cash card data 24 of each cash card 20 used on the same business day, and this information is stored in the regulation information storage unit 26. It is compared with regulatory information.
[0048]
The regulation information storage unit 26 is information written from the center terminal 13 via the prepaid card center 12, and the information changes in a predetermined period. In other words, the regulatory information was initially 10,000 yen, but now changes to 30,000 yen six months later, and 5,000 yen three months later. is there.
[0049]
In the present embodiment, the regulation information of 30,000 yen is stored in the regulation information storage unit 26, and the converted accumulated information (B ') of today's already traded transaction information is 5,000. Since it is a yen, it is understood that the current transaction data 25 is within the range of regulation.
[0050]
FIG. 3 is a diagram showing a processing flow of the prepaid card control device 5. The prepaid card control device 5 receives a ticketing inquiry from the prepaid card issuing machine 4 from the initial state (S1), and performs a ticketing check when receiving cash card data and transaction data (S2) (S3).
[0051]
If the ticket can be issued, the information stored in the database 27 is searched based on the cash card data and the transaction data (S4). On the other hand, as a result of the ticketing check, if a ticket cannot be issued, error processing is performed (S5).
[0052]
After searching the information stored in the database 27, it is checked whether there is any debit transaction of the corresponding cash card data on the day (S6). If there is a debit transaction for the relevant cash card data on the day, it is determined whether or not the transaction amount is within the regulation information range based on the sum of the transaction amount and the transaction amount up to the previous transaction (S7).
[0053]
On the other hand, if there is no debit transaction for the cash card data on the day, it is determined whether or not the transaction is within the range of the regulation information based on the transaction amount (S8).
[0054]
As a result of determining whether or not the transaction amount is within the regulation information range based on the sum of the transaction amount and the transaction amount up to the previous time, if the transaction amount is within the regulation information range, a ticketing permission notification is transmitted to the prepaid card ticketing machine 4 ( S10).
[0055]
On the other hand, if there is no debit transaction of the relevant cash card data on the day and the transaction is out of the range of the regulation information based on the transaction amount, an error process is performed (S9). Further, based on the transaction amount, if it is within the range of the regulation information, a ticketing permission notification is transmitted to the prepaid card ticketing machine 4 (S10).
[0056]
As a result of judging whether or not the transaction amount is within the regulation information range based on the total value of the transaction amount and the transaction amount up to the previous time, if it is out of the regulation information range, a ticketing rejection notification is transmitted to the prepaid card issuing machine 4. (S11).
[0057]
When the ticketing permission notice is transmitted to the prepaid card issuing machine 4 (S10), the system waits for a ticketing completion notice from the prepaid card issuing machine 4 (S12), and issues a ticketing completion notice, cash card data, and transaction data from the prepaid card issuing machine 4. Is received (S13), the information stored in the database 27 is updated based on the cash card data and the transaction data (S14), and the state is initialized (S15).
[0058]
On the other hand, after transmitting the ticketing refusal notice to the prepaid card issuing machine 4 (S11), the system enters the rejection completion notification waiting state (S16). When the ticketing refusal completion notice comes from the prepaid card issuing machine 4 (S17), the initial state is set. It becomes a state (S15).
[0059]
FIG. 4 is a diagram showing the processing of the debit card processing terminal 3, the prepaid card issuing machine 4, and the prepaid card control device 5. In other words, FIG. 2 illustrates a case where the prepaid card control device 5 issues a ticketing permission and concludes a transaction.
[0060]
The debit card processing terminal 3 reads the card information by inserting the debit card and accepts the input of the personal identification number. In the present embodiment, the selection of the amount of the prepaid card to be purchased is requested, but the request may be made by the prepaid card issuing machine 4 requesting the selection of the amount of the prepaid card to be purchased.
[0061]
The debit card processing terminal 3 converts the transaction inquiry information and the read card information, and transmits the converted cash card data and transaction data to the prepaid card issuing machine 4.
[0062]
The prepaid card issuing machine 4 transmits the ticketing inquiry information, the converted cash card data and the transaction data to the prepaid card control device 5. The prepaid card control device 5 confirms the regulation information from the prepaid card center 12 in advance, and the permission of the debit transaction is determined based on the confirmation information.
[0063]
Then, the information of ticketing permission is transmitted from the prepaid card control device 5 to the prepaid card issuing machine 4. When the prepaid card issuing machine 4 receives the information of the ticketing permission, it transmits the information of the transaction permission to the debit card processing terminal 3.
[0064]
Upon receiving the transaction permission information, the debit card processing terminal 3 transmits debit transaction inquiry information to the debit card processing center 8. Upon receiving the inquiry information of the debit transaction, the debit card processing center 8 transmits the information to, for example, the A bank center 9 in this embodiment.
[0065]
Upon receiving the inquiry information about the debit transaction from the debit card processing center 8, the A bank center 9 confirms the account information based on the information, and transmits a transaction permission signal to the debit card processing center 8. Then, the debit card processing center 8 transmits a transaction permission signal to the debit card processing terminal 3.
[0066]
Upon receiving the transaction permission information, the debit card processing terminal 3 transmits a transaction permission signal to the prepaid card issuing machine 4. Upon receiving the transaction permission signal, the prepaid card issuing machine 4 issues a prepaid ticket and transmits a ticketing completion signal to the prepaid card control device 5.
[0067]
Then, the debit card processing terminal 3 issues a receipt indicating that the transaction has been completed. When the prepaid card control device 5 receives the ticketing completion information, it updates the transaction information corresponding to the converted cash card data.
[0068]
FIG. 5 is a diagram showing another process of the debit card processing terminal 3, the prepaid card issuing machine 4, and the prepaid card control device 5. That is, this drawing describes a case where the prepaid card control device 5 rejects a ticket and rejects a transaction.
[0069]
The debit card processing terminal 3 reads the card information by inserting the debit card and accepts the input of the personal identification number. In the present embodiment, the selection of the amount of the prepaid card to be purchased is requested, but the request may be made by the prepaid card issuing machine 4 requesting the selection of the amount of the prepaid card to be purchased.
[0070]
The debit card processing terminal 3 converts the transaction inquiry information and the read card information, and transmits the converted cash card data and transaction data to the prepaid card issuing machine 4.
[0071]
The prepaid card issuing machine 4 transmits the ticketing inquiry information, the converted cash card data and the transaction data to the prepaid card control device 5. The prepaid card control device 5 confirms the regulation information from the prepaid card center 12 in advance, and determines whether the debit transaction is possible based on the confirmation information.
[0072]
When the restriction information is exceeded, ticketing rejection information is transmitted from the prepaid card control device 5 to the prepaid card issuing machine 4. When the prepaid card issuing machine 4 receives the information of the ticket refusal, the prepaid card issuing machine 4 transmits the information of the transaction refusal to the debit card processing terminal 3.
[0073]
Upon receiving the transaction refusal information, the debit card processing terminal 3 issues a transaction-disabled receipt. Further, the prepaid card issuing machine 4 displays that transaction is not possible and notifies the prepaid card control device 5 of the completion of the ticketing refusal process.
[0074]
By performing such processing, the transaction control can be performed by the prepaid card control device 5, so that the debit card processing center 8 does not need to prepare hardware having a very large processing capacity. In addition, it can be assumed that the number of accounts of the converted cash card to be recorded by the prepaid card control device 5 is about 1,000 even if the number is estimated at most. It is considered that there is almost no burden even if this amount of data is given to the prepaid card control device 5.
[0075]
Furthermore, since regulation can be performed not at the unit of the debit card processing terminal 3 but at the store level, regulation at a store where a plurality of debit card processing terminals 3 are installed or terminal replacement at the time of failure of the debit card processing terminal 3 can be performed. Can clear the problem that the regulation information is released.
[0076]
When communicating with the debit card processing center 8, the normal debit card processing terminal 3 uses encryption algorithms FEAL, DES, RC6, RSA, etc., which have a certain evaluation. And the value after conversion is a function of a bijective relationship, and the encryption algorithm and encryption key used are not disclosed in the prepaid card issuing machine 4 or the prepaid card control device 5. It is not necessary to prepare a special data conversion process for the debit card processing terminal 3 to transmit the cash card data to the prepaid card issuing machine 4 or the prepaid card control device 5.
[0077]
Therefore, although the prepaid card control device 5 has cash card data encrypted by these encryption algorithms, there is no means for decryption, and the prepaid card control device 5 cannot be used for purposes other than debit card transaction regulation.
[0078]
Various changes or additions can be made to the transaction processing system of the present embodiment without departing from the gist of the transaction processing system. For example, the portion for controlling the transaction of the debit card may be provided in the ticketing unit 7 in addition to the prepaid card control device 5.
