Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a credit card (hereinafter referred to as "C card"), a prepaid card (hereinafter referred to as "P card") or a debit card (hereinafter referred to as "D card").
Payment related to the sale of goods (including the provision of various services and the sale of goods as goods) using cashless cards (hereinafter, simply referred to as these cashless cards). The present invention relates to a card payment member store terminal, a card payment service system, and a card validity determination method in card payment.

[0002]

2. Description of the Related Art Recently, consumers have no cash.
A full-fledged cashless era, in which payment is made by postpaid or immediate payment cards or electronic money on the Web, is about to begin. In particular, a D card (formally called a “J-DEBIT” card in Japan,
The service provided by credit cards) is expected to expand rapidly due to the convenience that financial institution cards can be used without any procedures. The service was started in some areas in January 1999 and started in March 2000. Full-scale operation has begun in May, and it is expected that the card payment service will be available 24 hours 365 days anytime and anywhere.

[0003] In reality, there are financial institutions such as S bank and DK bank that can be used for 24 hours. Generally, 8: 0
It is available to all financial institutions from 0 to 21:00, and the time zone differs depending on the financial institution that issued the card (D card).

[0004] Various retailers and various service providers prepare necessary facilities for handling cards, and collect payment for sold products and provided services through a network system for performing settlement corresponding to the cards. . The retailer that enables card payment using such a network system is hereinafter referred to as a “member store”. The required equipment prepared by the member store is positioned as a so-called network system terminal. In the following, “sale of goods” includes provision of services. Similarly, "purchase of goods" includes provision of services.

As a payment example using a card, the "payment method after payment" using a C card as described above has been widely used. In this method, after the product is sold, the C of the issuing financial institution designated through the credit company that issued the C card
A predetermined amount is debited from the designated account of the cardholder, and the price associated with the sale of the product is usually 1-2
Paid after months.

[0006] On the other hand, payment using a P card is performed by "payment in advance" method. By paying a predetermined amount to the member store in advance, the P amount is stored in a storage unit such as a magnet or an IC of the P card.
The card is issued by the affiliated store, and each time the merchandise is sold, the amount is updated by reducing the predetermined amount stored in the P card and payment is made.

[0007] Such a P-card is particularly effective, for example, for refueling at gas stations and for paying tolls on highways.
The payment side can pay for the product purchase without preparing cash every time, and the merchant side can quickly collect the price for the product sale without preparing change, and the effective use of funds by prepaid is possible. is there. Note that the payment / collection of the consideration will not be performed beyond the balance of the P-card, and therefore, even if the P-card is lost, the damage suffered by the owner is controlled by the balance of the P-card itself.

A D card is positioned between the "prepayment method" and the "post-payment method", and the so-called "immediate payment method" is used for settlement of goods and services.

[0009] The D card is for performing payment using a cash dispenser card issued by a financial institution.
Called a card. There is no issuance of the D card itself (the D card itself does not physically exist). However, in the following description, for example, it is expressed as "a financial institution that has issued a D card", which means a financial institution that has issued a card treated as a D card.

[0010] When a merchant sells a product, the card held by the customer who wants to purchase the merchandise is inserted into the terminal of the merchant as a D card, and the purchaser is delivered to the financial institution of the card. Entering the password into the terminal and entering the price for merchandise sales at the merchant, the purchaser's financial institution account corresponding to the card is immediately The sales price is deducted. Then, payment processing is performed on the financial institution account designated for each member store within 2 to 3 days at the latest.

[0011] There are the following advantages in the member stores, such as purchasers who are users, retailers, and service providers.
In other words, if you are a C card or D card member store, you can purchase products anywhere without having to carry cash, and for D cards, you can open a new bank account without having to issue a new card. By using the corresponding card easily, it is possible to pay for the purchase of goods within the range of the balance or credit of the bank account. In addition, since the settlement price is almost immediately transferred to the designated account, it is possible to quickly, reliably and efficiently collect the price of the sales product, and furthermore, it is possible to increase sales by making it difficult to miss sales opportunities.

Nikkei Internet BIZTECH NEWS dated August 28, 2000, entitled "Six Major Credit Companies Cooperate in Mobile Payment Method" on August 25, 2000. "PKIC" for making secure payments using C-cards on PCs and game consoles
Consortium was established with the aim of promoting the use of "C" (pea kick). PKICC increases the security of payment by issuing digital certificates to devices such as mobile phones in advance, and performing mutual authentication between the mobile phone, EC (e-commerce) site, and payment center. It is. There is also an attempt to increase the security of settlement by distributing digital certificates to mobile phones and game machines in advance.

[0013]

However, in the card payment service system or the card business providing system for paying for the purchase of a product by a card as described above, the card holder owns various cards, and furthermore, the card holder owns the card. Is a system or business provision method that is based on the premise that payment is made from the financial institution account of the purchaser who is the card owner only when payment for the purchase of the product is made.

In general, signature confirmation is used to assert that the user is the card owner as seen in a C card or the like. In order to satisfy the above, various devices as described below have been devised.

For example, the member store, CAFIS to be described later
Payment settlement information transmitted between centers and clearing centers is treated to ensure security by advanced encryption, and is also entered when a customer enters a password at the time of card payment to pay for product purchases Some devices such as a separate terminal for inputting the password are attached so that the password inside is not visible. Furthermore,
JP-A-09-330453 and JP-A-10-694
As disclosed in JP-A-63-63, there is also an attempt to perform identity verification using a retinal pattern peculiar to each purchaser.

[0016] All of the above-described devices for confirming the identity are intended to provide a means for confirming whether or not the identity of the user is at the time of payment for paying for the purchase of the merchandise by card.

However, it is possible to sniff a password, eavesdrop on what is input to a terminal, or use an identification number (for example, an account number of a corresponding financial institution, or a C card, Credit numbers) and passwords with a dedicated system,
By doing so, the so-called password is very easily clarified and the like, and it is premature to determine that the user is the only person who can input the password correctly.

Further, even if an attempt is made to ensure security by high encryption, the encryption is decrypted by a further encryption technique, and a fictitious commodity price is exploited by misusing a card number or password left in a retail terminal. In some cases, users may be charged for services and services provided. In addition, among the purchasers, one card may be used by the family or the like, so that the matching based on the retinal pattern may not be available.

In particular, in a card settlement service using a D card, since a card in a financial institution account can be used as a D card without performing a new registration procedure, a serious problem occurs for a purchaser who has lost the card. For example, an anniversary, such as the birthday of the person, is often used for the password of the card in terms of easy storage, and the password is often found by examining the anniversary. In addition, since the number is a four-digit number, the password can be determined by repeating trial and error at most 9999 times, and if the date is a date, the password can be determined in any of 365 days. Alternatively, the password can be easily found by reading information stored on the card.

[0020] In this way, the advantage that the D card is settled immediately is that if the card is turned upside down and the lapse of a few days without noticing the loss of the card, the deposit balance of the corresponding financial institution account will not be exactly the same. That advantage can be a disadvantage.

In the above-mentioned method of issuing a digital certificate to a mobile phone, the card itself is not authenticated. Therefore, the corresponding mobile phone must be always held together with the card. If it holds, it will be digitally authenticated.

The present invention has been made in view of the above circumstances, and provides a card payment member store terminal, a card payment service system, and a card validity determination method in card payment which solve the following problems. It was made for the purpose of.

First, an ID number for identifying various cards such as a C card, a P card or a D card and a password relating to the card are decrypted and illegally copied, or the decrypted password is input and the owner of the card is input. Third except for
To prevent unauthorized use. Then, even if the user does not notice the loss or theft of the card, it is possible to avoid a situation in which the deposit of the designated account of the financial institution related to the card has been lost.

DETAILED DESCRIPTION OF THE INVENTION "C" used in the following examples
AFIS Center "is the Credit And Fin
is an abbreviation for "Ance Information System", which refers to a shared-use network provided by NTT DATA Corporation.
Distribution companies, financial institutions, affiliated stores, etc. are nationwide ON-
It is connected via LINE and is mainly used for credit inquiry (also called credit) and sales management.

The "clearing center" is the same as the "C
AFIS Center "is a so-called information centralization center that centrally manages the payment information for the purpose of receiving transaction information related to credit and debit from the AFIS center as payment information and smoothing the flow of funds based on such information.
The card issuing financial institution receives the result of the transfer deducted from the user's account, collects and offsets such data, and transmits the data after deducting the commission of the financial institution to the settlement financial institution. Under such circumstances, it is called a clearing center (due to having a function of canceling out or totalizing payment information).

[0036] In recent years, mobile phones and PHSs have become widespread as mobile terminals.
Personal communication has become a reality where users can use communication services anytime and anywhere on their own terminals, on their own lines, and on their own numbers.

In order to realize such personal communication, the following three "main functions" must be realized.

On the one hand, as a mobile terminal, "terminal mobility (mobility)" must be realized such that a call can be transmitted from anywhere at any time and communication can be guaranteed even in a wide area even while moving.

Secondly, “portability of numbers” is indispensable so that communication with the same number as an individual is possible regardless of the number for identifying a mobile terminal.

Thirdly, various attempts have been made to enhance the “personal service” for enabling the future improvement of functions and diversification of communication services, and such attempts are selectively used in each mobile terminal. It needs to be possible. For example, the mobile terminal owner can freely use the "mail function" for transmitting short messages as characters, a mail and voice storage service corresponding to the absence of a destination, and searching various databases (hereinafter abbreviated as DB). Functions such as selecting and freely setting and controlling the functions of the mobile terminal correspond to the “personal service”.

In particular, in order to realize the "terminal mobility", it is necessary to keep track of the movement of each mobile terminal at all times.
For this purpose, a base station which is also called a wireless communication port of each mobile terminal is installed so as to cover a predetermined area.
Each base station has a mobile radio service area as an area that can cover a radio service. When each mobile terminal exits the mobile radio service area of the base station A, for example, and attempts to enter the mobile radio service area of the base station B, a position registration cancellation request signal is issued to the base station A, and A position registration request signal is issued to the station B.
As a result, the location information of the mobile terminal is changed from base station A to base station B. The request signal as described above is issued because the location information of the mobile terminal is stored in a server that manages a database that controls a personal communication service described later, and the mobile radio service is also stored in each mobile terminal. Each mobile terminal receives the information indicating the mobile radio service area from a different base station, so that the transmission of the position registration cancellation request signal and the position registration request signal is performed by each mobile terminal. Controlled.

In particular, when the mobile terminal attempts to turn off the power, the mobile terminal issues a position registration cancellation request signal immediately before the power is turned off, and then the power is turned off. As a result, the location information of the mobile terminal is cleared, and the mobile terminal is treated as a mobile terminal whose location is unknown. The location where the base station has received the location registration request signal or the address of the base station assigned to the base station is stored as the current location corresponding to the mobile terminal. Such a current position is stored in a personal communication service control database server (hereinafter, referred to as a P communication service control DB server) connected to the base station covered by the communication network as described above. In the following embodiments, the server and a plurality of personal communication base stations (not shown) are collectively referred to as a “network”, and the current position of each mobile terminal is shared and stored by the network. That the current location is stored in the network,
And the expression.

The current position of each mobile terminal stored in the network as described above is used as information for specifying a base station when calling the mobile terminal from the network. Such position information is used as a final destination for calling a mobile terminal from the network including not only one base station corresponding to the current position but also peripheral base stations. When the current position is viewed from the network side, the current position is “access”. Point ".

FIG. 1 is an example of the present invention, and is a block diagram showing a configuration of a wide area network in the embodiment.

In FIG. 1, a member store terminal 1 includes a card reader for reading card contents stored on a card, such as a card number for identifying the card and a password for certifying the owner, a password and sales information. It has a key input unit for inputting the amount and can access an authentication and credit server 2 such as a CAFIS center via a communication line (whether wired or wireless) to obtain authentication or credit information of a C card or D card. Is configured. The member store terminal 1 is also configured to be able to access a position management server 3 described later via a communication line. The member store terminal 1 requests the current position of the corresponding mobile terminal from the position management server 3 by a card number by network communication, and acquires necessary information. A printer is connected to the member store terminal 1,
Print the payment details as a result of card payment.

Prior to the card settlement, first, the member number of the card used for selling the merchandise and the position information of the member store terminal 1 are transmitted from the member store terminal 1 to the position management server 3, and the position management server 3. Then, the corresponding mobile terminal is determined by referring to a correspondence table described later in the location management server 3 from the card number. The position information of the member store terminal 1 is transmitted by transmitting the position information where the member store terminal 1 is installed to the position management server 3.
In order to grasp the position of the member store terminal 1, the terminal number of the member store terminal 1 is transmitted instead of transmitting the position information of the member store terminal 1, and the position management server 3 determines the position of the member store terminal 1 from the terminal number. Information may be searched.

Next, the location management server 3 designates the mobile terminal 6 and accesses a server having the location DB (for example, the P communication service control DB server 7).
The position information of the mobile terminal 6 corresponding to the card payment is obtained.

In the location management server 3, the password of the card number, the mobile terminal specified in advance for the card number, and the password are listed in a list format as shown in FIG. Is remembered.

The authentication credit server 2 is connected to a clearing center 4 and a credit company DB server 5 via a communication line.
01, 502, 503,... (Hereinafter, representatively referred to as a credit company DB server 5).

It is connected to a portable terminal (including a cellular phone, a PHS, or a PDA such as a mobile or a palm (not shown)) and a network and has a function of transmitting and receiving information, and can grasp its current position. Communication terminals such as laptop-type mobile personal computers (NWPC) are collectively referred to as mobile terminals 6. The mobile terminal 6 is generally a terminal for each cardholder and associated with the card.

In recent years, mobile phones equipped with functions for accessing and replying to e-mails and home pages, confirming positions, and the like have begun to spread. For example, there is a mobile phone provided with a function called “i-mode” related to a mobile phone provided by NTT Mobile Communication Network Corporation (hereinafter referred to as NTT DOCOMO).

This function is provided, for example, by a mobile phone compatible with “i-mode” which is an online service of NTT DOCOMO and a Mic.
Microsoft Exchange Exchange Server (Mic
Microsoft Exchange is a function realized through the gateway software "iLook" for mobile phones developed by NTT DOCOMO in cooperation with Microsoft (registered trademark). The same function will be added in the PHS in the future. Is also predicted.

The location management server 3 can easily acquire the current location of the mobile terminal 6 by accessing the P communication service control DB server 7. As described above, in the mobile terminal 6, the current position is always stored in the P communication service control DB server 7 which manages the mobile terminal 6 by the basic function of the mobile terminal itself. This makes it possible to specify the mobile terminal 6 and make an inquiry to the DB server 7.

Then, the location management server 3 transmits the acquired location at the time of card settlement to the affiliated store terminal 1, and the affiliated store terminal 1 determines the card validity in the card settlement based on the transmitted location information. to decide. As will be described later, the card validity may be determined in any of the member store terminal 1, the location management server 3, and the clerk of the member store terminal.

For the determination of the validity, the position management server 3 determines the card validity in the card payment based on the position at the time of the card payment acquired by the position management server 3, and determines the result of the position determination. The management server 3 may transmit to the member store terminal 1. Thus, the member store terminal may not have a means for determining card validity based on the position at the time of card payment.

FIG. 3 is a schematic diagram showing a homepage established by the location management server 3. Access the home page from the mobile terminal 6 (use the mobile terminal if the mobile terminal 6 can access the WEB;
The WEB may be accessed using an NWPC connected to the network so that the WEB can be accessed), a number for identifying a mobile terminal 6 such as a mobile phone or a PHS, a password for permitting setting registration change, and a corresponding cashless card. A number can be input and specified, and a card number can be associated with a mobile terminal.

Further, the member store terminal 1 accesses the homepage established by the location management server 3 shown in FIG. 4 by specifying a card number (for example, C123456890) and a password (for example, ABCDEFGH) and clicking the "Send" button. It is possible to acquire the result of determining the validity of the card at the time of card payment, as shown as a message such as "card payment is not possible" in FIG.

If access is made by the “details” button on the member store terminal 1, location information (eg, POS 123
4) can be obtained. The password used for the inquiry is a password for the member store terminal 1 (the password is used to specify the member store terminal 1 and can be regarded as a number specifying the member store terminal 1). Thus, the password is different from the password used by the mobile terminal 6, and the information obtained in accordance with the password is different.

The location management server 3 is an authentication credit server 2, a clearing center 4, or each credit company DB.
It may be included in the server 5. Alternatively, by utilizing the fact that the location management server 3 can be accessed from the member store terminal 1, "access from the member store terminal 1 to the authentication credit server 2" is performed on behalf of the "location management server 3 to the authentication credit server 2". In this way, the terminal 1 may be configured to group the member store terminals 1 at the end, and the “authentication credit server 2 that is in charge of one of the groups”.
The use of the location management server 3 as an “intermediate server to” provides an effect of decentralizing centralized access from the member store terminal 1 to the authentication and credit server 2.

By specifying the “details” button provided in the screen of FIG. 3, the card number associated with the mobile terminal 6 and the base station in the mobile radio service area to which the mobile terminal 6 belongs are assigned. Such position information can be obtained.

Next, the procedure in which the cardholder purchases a product by card payment is divided into the first half and the second half, and FIG.
This will be described with reference to the flowchart of FIG. When the location is referred to at the merchant terminal 1 for card payment and it is determined whether card payment is possible or not, the location information indicating the location of the mobile terminal at the time of card payment is obtained by using the location management function of the location management server 3. The procedure for checking will be described.

In STEP 601, it is assumed that the card holder visits a member store in order to purchase goods by card payment and inserts the card into the member store terminal 1. Merchant terminal 1
From here, the card number for performing card payment to the position management server 3 and the password unique to the member store terminal are specified on the home page screen of the position management server 3 shown in FIG. To send over the network.

At STEP 602, a number specifying the mobile terminal 6 corresponding to the card number stored inside the location management server 3 is searched for and obtained.

At STEP 603, the P communication service control DB server 7 is first accessed by the number specifying the mobile terminal received from the member store terminal 1, and the current position information of the mobile terminal 6 is obtained. Then, the member store terminal 1 searches the member store terminal position information table shown in FIG. 5 stored in the location management server 3 from the password unique to the member store terminal 1 and received from the member store terminal 1, and obtains the position information of the member store terminal 1. To get.

At STEP604, the location information of the mobile terminal 1 obtained at STEP603 is compared with the location information of the member store terminal 1. The comparison may be performed based on whether or not the codes as the base station match. Further, the comparison may be performed based on whether or not codes as base stations are adjacent to each other.

For example, when making a comparison based on whether or not they are adjacent to each other, the following judgment is made. Each time a new base station is added, an adjacent base station is picked up, and a pair of the new base station and the adjacent base station is stored in a pair table (not shown). The base station indicated by the location information of the member terminal 1 searches the pair table accumulated with the addition of the base station in this way, and the base station indicated by the location information of the mobile terminal 1 is included in the corresponding pair. It is determined whether or not it has been performed. According to this determination method, the base stations adjacent to each base station can be confirmed without omission. If the result of the above comparison indicates that they do not match or are not adjacent, STEP 60
Proceed to 6 and proceed to STEP 605 if it is determined that they match or are adjacent.

In STEP 605, a message “card approval is possible” is returned to the member store terminal 1 and the process proceeds to STEP 607. The flowchart after STEP 607 will be described with reference to FIG.

In STEP 606, "I cannot approve the card."
Is returned to the affiliated store terminal 1, the affiliated store terminal 1 receives the message, stops selling the goods by card payment, and ends the processing of this flowchart.

In STEP 607, it is determined that the card settlement is permitted as the intention of the cardholder, and the credit information such as the passbook balance and the credit limit of the card is transmitted from the member store terminal 1 to the authentication credit server 2. Upon being inquired, the authentication credit server 2 further checks with the corresponding credit company according to the card.

At STEP 608, the result of the inquiry at STEP 607 is judged, and if credit is possible, the flow proceeds to STEP 609; otherwise, the flow proceeds to STEP 606, and the processing of this flowchart is ended as a result. In STEP 609, information necessary for the transaction is transmitted to the authentication credit server 2, and the sales processing is advanced. Also applicable credit company 5 and clearing center 4
Send necessary information to

In STEP 610, the settlement financial institution of the card issuing financial institution is instructed to transfer the corresponding amount to the designated financial institution of the member store. The transfer will be same-day settlement or post-payment settlement depending on the type of the card. The process of this flowchart ends.

According to the flowcharts shown in FIGS. 6 and 7, when the purchase of goods is performed without cash and the card settlement is attempted, the intention of the card owner to use the card always refers to the position management server 3. Will be confirmed.

[0073]

As described above, according to the present invention, the P communication service control DB server automatically manages the location information of the mobile terminal 6 corresponding to the card holder instead of the card holder. There is no need to notify the credit company or card issuing financial institution of the loss of the card, and if the location of the mobile terminal corresponding to the card is clear, fraud outside the mobile wireless service area indicated by the location information registered in the mobile terminal The card is not used, and the location information is canceled by taking measures such as turning off the power of the mobile terminal, so that a sense of security that the card will not be used by others without permission can always be maintained.

Therefore, there is an effect that the amount of insurance relating to the unauthorized use of the card is kept low, which is expected to contribute to the rapid expansion of the card.
