Description

  The present invention relates to a credit card usage notification system, and more particularly, to a credit card usage notification system that notifies a user of information related to the usage when performing transactions such as buying and selling using a credit card.

  Payments using credit cards are in widespread use. In particular, the use of online payment through the Internet or the like is becoming widespread, and credit cards are further used as the payment means.

  When a credit card is used, an authorization process for using the credit card is executed by reading a magnetic stripe attached to the credit card. Authorization processing means that a credit card member store confirms a user's credit with a credit card service provider.

  For example, when a credit card is used at a credit card member store, an authorization system owned by the credit card service provider and a POS (Point Of sales) computer or a CAT (Credit Authorization Terminal) terminal installed at the member store The authorization process is executed by exchanging information between the two.

  Specifically, the POS computer that has read the magnetic stripe attached to the credit card sends an authorization request message including the card number encoded in the magnetic stripe and the input payment amount to the authorization system. Performs a check on the credit limit associated with the card number. As a result, an authorization / non-approval message for card use is transmitted from the authorization system to the POS computer.

  The authorization process described above is the same for online payment. In online payment, instead of a POS computer, an authorization generated by a computer of an online payment company based on card information and a payment amount received from a user's computer device. A request message is sent to the authorization system. Such processing prevents unauthorized use of credit cards.

  When credit card usage is approved through the authorization process described above, a sales information message including the card number, member store identification number, payment amount, etc. is sent from the POS computer to the sales system owned by the credit card service provider. Sent. In the sales system, the sales information is stored, and the user's usage details for each month are notified to the user at a timing such as monthly (for example, the WEB site provided by the sales system is accessed through the user's computer device). Or by mailing paper forms output by the sales system). By notifying the user of the usage details in this way, unauthorized use of the credit card can be detected afterwards.

Japanese Patent No. 5148161

  Needless to say, the authorization process described above cannot completely prevent unauthorized use of a credit card. Although it has been described above that unauthorized use of a credit card can be detected afterward by notifying the user of the usage details, the timing for making this notification is not immediately performed after the credit card is used. . Along with this, the timing for detecting unauthorized use is also delayed.

  Patent Document 1 discloses a card use notification system that notifies breaking information including a usage approval amount both when the use of a credit card is approved and when the use of a credit card is not approved. . In the card use notification system according to Patent Document 1, since the bulletin information is notified at the timing of authorization when the credit card is used, it is possible to solve the problem that the timing for detecting unauthorized use as described above is delayed.

  However, in the card use notification system according to Patent Document 1, the bulletin information is notified even when the use of the credit card is not approved, but if the use is not approved, the credit card cannot be used. The need for notification is low, and it may be troublesome to notify even in such a case. In particular, although it is expected that there are users who wish to notify breaking information only through non-face-to-face transactions such as online payment, the card usage notification system according to Patent Document 1 considers face-to-face transactions and non-face-to-face transactions. Without having to do so, you will be notified of breaking information in the use of both transactions.

  Further, the card use notification system according to Patent Document 1 determines whether or not to approve the use based on whether or not the credit card can be used (validity, available amount, etc.). Is performed when it is determined that is available. Therefore, it cannot be said that the card use notification system according to Patent Document 1 can sufficiently prevent unauthorized use.

  Furthermore, the card use notification system according to Patent Document 1 notifies the bulletin information by determining whether or not the credit card can be used. However, in this mechanism, when the authorization process by the authorization system described above is not executed, , Can not notify the bulletin information.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a credit card use notification system that notifies information related to the use of a credit card only when the user needs it.

  In order to solve the above problems, a credit card usage notification system according to the present invention is a credit card usage notification system connected to a client computer or a POS computer, and receives a sales information message from the POS computer.

  The display unit 45 is a display screen that displays an input / output interface displayed by downloading a WEB page from the authorization server 1 and / or the sales server 2 or when the control unit 42 executes a predetermined program.

  Next, an example of processing executed by the credit card usage notification system according to the embodiment of the present invention will be described with reference to the flowchart of FIG. In this embodiment, an example in which a user uses a credit card at a member store will be described.

  First, as a premise of the processing described in FIG. 3, the user registers the usage notification setting information through the usage notification setting information registration screen displayed on the display unit 45 of the client computer 4 owned by the user. To do. FIG. 4 shows an example of the usage notification setting information registration screen 400.

  As shown in FIG. 4, the usage notification setting information registration screen 400 includes a card usage notification presence / absence selection radio button 401, a notification target transaction selection radio button 402, and a notification target amount input box 403.

  The card use notification presence / absence selection radio button 401 is a radio button for selecting whether or not to receive a notification mail indicating that the card has been used when the user uses the credit card. Only users who have selected “Receive” with the card usage notification presence / absence selection radio button 401 are subject to processing by the credit card usage notification system according to the present embodiment.

  The notification target transaction selection radio button 402 receives a notification e-mail for all transactions when the user uses a credit card, or a non-face-to-face transaction (such as online payment, does not go through the POS computer 3 by a store clerk at a member store. This is a radio button for selecting whether to receive a notification mail only for (transaction). Moreover, in other embodiment of this invention, it is also possible to choose to receive notification mail only about face-to-face transaction. By receiving the notification mail, the user can quickly grasp that the credit card has been used.

  A notification target amount input box 403 is an input box for designating an upper limit amount of a payment amount using a credit card by a user, which is a condition for receiving a notification mail. For example, when 10000 yen is input in the upper column “once” of the notification target amount input box 403, a notification mail is received when the settlement amount in one transaction is 10000 yen or more. When 50000 yen is input in the lower column “1 month” of the notification target amount input box 403, a notification mail is received when the total settlement amount of transactions for one month is 50000 yen or more.

  When the above-described information is input on the usage notification setting information registration screen 400, the communication unit of the client computer 4 receives a usage notification setting information message (including information such as a card number and a monthly limit) including the input information. Send to the authorization server 1. The transmitted usage notification setting information message may be shared by the authorization server 1 and the sales server 2.

  When the communication unit 11 of the authorization server 1 receives the usage notification setting information message, the control unit 12 displays the target record of the user data table 500 stored in the auxiliary storage unit 14 based on the received usage notification setting information message. Update. The user data table 500 is also stored in the auxiliary storage unit 24 of the sales server 2 in the same manner. An example of the user data table 500 is shown in FIG.

  As shown in FIG. 5, the user data table 500 includes data items “card number”, “name”, “monthly limit amount”, “cumulative usage amount”, “notification presence / absence”, “notification transaction”, “notification”. “Target amount 1”, “Notification amount 2”, “Status”, and “Mail address” are included. In the data items “card number”, “name”, “monthly limit” and “email address”, the number assigned when the user joins the credit card / registered information is set.

  In the data items “notification presence / absence”, “notification target transaction”, “notification target amount 1” and “notification target amount 2”, information included in the usage notification setting information message is set. 1: “Receive”, “Notification Target Transaction” is “1: All Transactions”, “Notification Target Amount 1” is “10000 (upper settlement amount per transaction)” and “Notification Target Amount 2” is “ “50000 (the upper limit of the settlement amount per month)” is set.

  The data item “cumulative usage amount” is set to the total settlement amount of transactions in which the corresponding user uses a credit card every month. That is, for each month, the value of this data item is added each time a credit card is used.

  In the data item “state”, a value indicating a valid / invalid state of the corresponding credit card is set. For example, “1: valid” is set. For example, “2: Invalid” is set in the “state”, for example, when the user loses the credit card and reports the card use suspension.

  In addition, a member store data table 600 shown in FIG. 6 is stored in the auxiliary storage unit 14 of the authorization server 1. The member store data table 600 is a database table that stores information on all member stores that are affiliated with the service provider, and is an industry code (for example, a value indicating the type of member store such as a bookstore, convenience store, or precious metal store). And information such as an address.

  Further, a usage history data table 700 shown in FIG. 7 is stored in the auxiliary storage unit 14 of the authorization server 1. The usage history data table 700 is a database table that stores information related to a user's past usage history, and is used to determine whether a credit card, which will be described later, is fraudulent.

  As shown in FIG. 7, the usage history data table 700 includes data items “user number”, “average settlement amount”, “maximum settlement amount”, “use prefectures (all prefectures such as Hokkaido and Aomori)”, and “ Includes “use industry”.

  The data items “Average settlement amount” and “Maximum settlement amount” are the average settlement amount and the maximum settlement amount for transactions in which the corresponding user uses a credit card. These values are updated each time a credit card is used. Is done.

  The data item “prefecture used” represents the frequency of use for each prefecture to which the member store where the user used a credit card belongs. For example, each time a user uses a credit card at a member store, 1 is added to the item of the prefecture to which the address of the member store belongs (reference is made based on the data item “address” in the member store data table 600). .

  The data item “use industry” represents the use frequency for each industry to which a member store using a credit card by a user belongs. For example, whenever a user uses a credit card at a member store, 1 is added to the item of the industry to which the member store belongs (reference is made based on the data item “industry number” of the member store data table 600). This “use industry” may manage the frequency of use for all pre-defined industries, or a specific industry (for example, precious metal stores tend to be statistically expensive payments or fraudulent use) The frequency of use may be managed only for easy industries).

  In this embodiment, the usage history data table 700 has a data record for each user, but may have a data record for each user and for each year / month.

  In this state, when the user uses the credit card at the member store, the magnetic stripe attached to the credit card is read by the reader 36 of the POS computer 3 and the settlement amount is input to the POS computer 3. Then, the card number and payment amount encoded in the magnetic stripe are acquired by the control unit 32 (step S301). Next, the control unit 32 generates an authorization request message including the card number, the payment amount, and the member store identification number stored in the auxiliary storage unit 34, and the communication unit 31 transmits the authorization request message to the authorization server 1 ( Step S302).

  When the communication unit 11 of the authorization server 1 receives the authorization request message, the control unit 12 acquires the corresponding user data record from the user data table 500 based on the card number included in the authorization request message (step S303). ).

  Next, based on the payment amount included in the authorization request message received in step S303 and the data items “monthly limit amount” and “state” included in the user data record acquired in step S303, the control unit 12 The validity of the credit card is determined (step S304).

  Here, in the validity determination in this step, the data item “status” included in the user data record acquired in step S303 is “1: valid”, and the settlement amount included in the authorization request message is the data item. It is determined whether the amount within the “monthly limit amount” and the sum of the settlement amount and the value set in the data item “cumulative usage amount” is within the monthly limit amount. If all the conditions are satisfied as a result of the determination, the credit card is determined to be “valid”. On the other hand, if any one of the conditions is not satisfied, the use of the credit card is determined as “non-approved”. In this embodiment, the validity of the credit card is determined based on whether or not the above-described conditions are satisfied. However, this condition is merely an example, and even if the validity is determined based on various criteria. Good.

  If the use of the credit card is determined as “non-approved” in the validity determination in step S304 (No in step S305), a non-approval message indicating that the card use is non-approved is transmitted to the POS computer 3. (Step S306), the process is terminated. On the other hand, when it is determined that the credit card is “valid” (Yes in Step S305), the control unit 12 determines the member store data table 600 based on the member store identification number included in the authorization request message received in Step S303. The corresponding member store data record is acquired from (step S307).

  Next, the control unit 12 acquires a corresponding usage history data record from the usage history data table 700 based on the card number included in the authorization request message received in step S303 (step S308).

  Next, the control unit 12 receives the payment amount included in the authorization request message received in step S303, the data items “address” and “business type number” included in the member store data record acquired in step S307, and acquired in step S308. Based on the data items included in the usage history data table 700, it is determined whether or not the credit card is illegally used in accordance with the criteria shown in Table 1 (step S309). Note that the determination criteria shown in Table 1 are merely examples, and various conditions for determining unauthorized use of a card can be set.

  In conditions 1 and 2, it is determined whether or not the settlement amount of the transaction using the corresponding credit card exceeds a certain amount or more compared to the past average settlement amount / maximum settlement amount. This is because, in the case of statistically high-payment that does not exist in the past usage history, there is a possibility of unauthorized use.

  In condition 3, it is determined whether or not the type of business to which the member store using the corresponding credit card belongs is a type of business that has hardly been used at all in the past. This is because, statistically, there is a possibility of fraudulent use when using a credit card at a member store belonging to an industry that does not exist in the past usage history (for example, high prices such as jewelry stores) Used at a merchant that belongs to a jewelry store even though it has never been used at a merchant that belongs to an industry that tends to settle.)

  In condition 4, it is determined whether or not the prefecture where the member store using the corresponding credit card is located is a prefecture that has hardly been used at all in the past. This is because statistically there is a possibility of fraudulent use when using a credit card at a member store located in a prefecture that does not exist in the past usage history (for example, in Okinawa Prefecture) When used at a franchise located in Okinawa Prefecture, even though it has never been used at a franchise in the past). In another embodiment of the present invention, after a card is used for face-to-face use in a certain prefecture, the card is also used illegally when there is a card use for face-to-face use in another prefecture far away. It is also possible to judge.

  When any one of the conditions 1 to 4 shown in Table 1 or any combination is satisfied, the use of the credit card is determined as “illegal use”. On the other hand, when none of the conditions 1 to 4 is satisfied, the use of the credit card is determined as “normal use”. This unauthorized use determination condition is merely exemplary, and may be determined based on various conditions that may be unauthorized use from past statistics.

  If it is determined as “normal use” in the determination of unauthorized use in step S309 (Yes in step S310), the use of the credit card is determined as “approval” (step S311).

  On the other hand, when it is determined that the use of the credit card is “illegal use” (No in step S310), the use of the credit card is determined to be “hold” (step S312). In this case, the communication unit 11 of the authorization server 1 transmits a pending message to the POS computer 3 (step S313). In this case, the process proceeds to step S316.

  Further, the control unit 12 generates pending state data (not shown) including at least a card number, a settlement amount, and a business type number (or a prefecture), and stores it in the auxiliary storage unit 14. This hold state data is data indicating that the hold state is managed every time the credit card is used, and may be a database table or a data file.

  If it is determined that the use of the credit card is “pending”, the credit card number is the same as the card number included in the hold status data, and the payment amount is the same as the payment amount or a payment amount within a certain range. If the credit card is used later at a member store that exists and belongs to the same or similar business number, it is similarly determined to be fraudulent.

  If it is determined that the credit card usage is “approved” in step S311, the communication unit 11 of the authorization server 1 determines that the credit card usage is determined to be “approved” in step S311. An approval message indicating approval is transmitted to the POS computer 3 (step S314).

  Upon receiving the approval message, the control unit 32 of the POS computer 3 sells the sales information message including the card number acquired in step S301, the payment amount, the member store identification number stored in the auxiliary storage unit 34, and the number of payments. It transmits to the server 2 (step S315). Through this process, the sales server 2 records the sales information of the transaction using the credit card by the user and manages it as the usage details of the user. Note that this sales information recording is the same as that performed by a system provided by a conventional provider of a credit card service, and therefore detailed description thereof is omitted in this specification.

  Next, the control unit 12 generates a usage notification message including the items shown in Table 2, and the communication unit 11 uses the destination indicated by the data item “mail address” included in the user data record acquired in step S303. The data is transmitted to a certain client computer 4 (step S316).

  The usage notification message in step S316 is transmitted according to the usage notification setting information input on the usage notification setting information registration screen 400. For example, when “2: only non-face-to-face transaction” is set in the data item “notification target transaction” included in the user data record acquired in step S303, non-face-to-face transaction (online payment, A usage notification message is sent only when usage is not eligible. When “10000” is set in “notification target amount 1”, a usage notification message is transmitted only when the settlement amount is 10,000 yen or more. When “50000” is set in “notification target amount 2”, a usage notification message is transmitted only when the total settlement amount for the corresponding month is 50000 yen or more.

  The authorization request message conforms to, for example, the standard of electronic messages related to financial transactions such as ISO 8583. For example, whether the credit card usage of the user is a non-face-to-face transaction by “POS input mode” defined by ISO 8583, for example. It can be determined whether or not. The same applies to a sales information message to be described later.

  When the usage notification message is transmitted to the client computer 4 in step S315, the control unit 42 of the client computer activates the mailer, whereby the usage notification mail shown in FIG. In one embodiment of the present invention, it is possible to use an application that can receive a message in addition to the mailer.

  When it is determined that the use of the credit card is “normal use”, the settlement amount of the transaction using the credit card by the user is displayed as the card usage bulletin (use notification mail 801 shown in FIG. 8A). . When it is determined that the use of the credit card is “illegal use”, a message indicating that the user is in the settlement amount of the transaction using the credit card and the hold state is displayed as the card hold notification (FIG. 8 ( Use notification mail 802) shown in b).

  Note that when the identity of the user is confirmed in the hold status, the above-mentioned hold status data is deleted, and the same credit card number as the card number included in the hold status data is the same as the payment amount or within a certain range thereof. And later use of credit cards at member stores belonging to the same or similar industry number is approved. In another embodiment of the present invention, the pending state data may be invalidated by setting a value in a flag without being deleted.

  Specifically, the user uses his / her client computer 4 to access the URL site shown in FIG. 8B (at the time of this access, the card number (or assigned to each user). Authentication is performed by entering the user number and password. When accessed, a hold release screen 900 shown in FIG. 9 is displayed on the display unit of the client computer 4.
