Description:
BACKGROUND 
       [0001]    The present invention generally relates to a card payment system and method and, more particularly, to a self-card payment system and method using a mobile communication terminal, which designate a mobile communication terminal capable of reading card information from the magnetic and IC chips of a card as a virtual card payment terminal only once per payment, and allow the user of the mobile communication terminal to pay a purchase amount consumed in online and offline environments by personally touching a card to the mobile communication terminal designated as the virtual card payment terminal. 
         [0002]    Generally, as methods of paying for goods such as products or food, cash payment methods for paying in cash and card payment methods for paying with a credit card, a debit card, or a cash card (T-money card) have been chiefly used. 
         [0003]    In the past, cash payment methods were widely used, but the use of cards has rapidly increased owing to a variety of conveniences in Internet banking, Internet payments, and offline payments. 
         [0004]    Generally, a credit card payment system includes an affiliated store terminal unit (not shown) for acquiring the card information of a credit card and transmitting the card information together with payment amount information, and a financial system (not shown) for receiving the payment amount information and the card information and processing the authorization of a transaction with the corresponding credit card company. 
         [0005]    In an offline environment, the affiliated store terminal unit is the card payment terminal (or variously referred to as a “credit card reader” or the like) of an affiliated store, and the financial system may be any of a Value Added Network (VAN) company server, a plurality of card company servers, bank servers, etc. In this case, the affiliated store terminal unit and the VAN company server are typically connected to each other through the private line of a Public Switched Telephone Network (PSTN). However, recently, some affiliated store terminal units are even equipped with a function of accessing the Internet. 
         [0006]    Further, in an online environment, the affiliated store terminal unit may be a payment module provided by a corresponding online retail shopping site, and the financial system may be any of a Payment Gateway (PG) company server, a plurality of card company servers, and a plurality of bank servers. In this case, the affiliated store terminal unit and the PG company server may be typically connected to each other over the Internet. 
         [0007]    Typically, the affiliated store terminal unit transmits card information and payment amount information acquired from a purchaser to a financial system, and requests the authorization of a card transaction from the financial system. The financial system, having received such an authorization request, determines the validity or invalidity of the card, the credit status of the card holder, the credit limit of the credit card that is desired to be used, etc., and provides the results of authorization to the affiliated store terminal unit. 
         [0008]    However, such an existing card payment method is problematic in that, when a user orders food for delivery over the phone or purchases a product online via an Internet site, card information must be provided to a seller over the phone, must be entered into the payment module of the website, or must be previously registered in a website provision server, so that card information may be easily leaked to a third party such as a hacker or a seller, and thus the risk of financial accidents caused by the leakage of card information is always present. 
         [0009]    Due thereto, a problem arises in that, when ordering food for delivery over the phone, users intend to pay in cash most of the time, rather than using a card, thus making it impossible to order something for delivery when the user does not have cash. 
         [0010]    In order to solve these problems, wireless card payment terminals have recently been popularized and used, but the burden on sellers has increased due to the prices and usage fees of the terminals.

         [0097]    The payment authentication module  317  is configured to, when card information is received from the mobile communication terminal  100  in response to the transmission of the bill, access the server corresponding to the card information, which is one of the VAN company server  410 , the PG company server  420 , and the financial server  430 , check the validity of the card, and transmit a payment request signal, which includes the card information and the payment amount information, to the card payment terminal  200  if there is no abnormality in the card validity. 
         [0098]    The transaction record management module  318  stores payment information based on the processing of payment authentication performed by the payment authentication module  317  while mapping the payment information to the information of the affiliated store that transmitted the payment information in the affiliated store DB  340 , and thereafter manages the payment information. The transaction record management module  318  may be configured to receive a transaction record based on the completion of final card payment from the card payment terminal  200 , store the transaction record while mapping the transaction record to the corresponding affiliated store information in the affiliated store DB  340 , and thereafter manage the transaction record. 
         [0099]      FIG. 6  is a flowchart showing a method for allowing a user to register as a member for self-card payment using a mobile communication terminal according to the present invention. 
         [0100]    First, personal member registration methods for using a self-card payment service according to the present invention include a web registration method using a mobile communication terminal, which accesses the web server  230  via the mobile communication terminal  100  for member registration; a web registration method using a computer, which accesses the web server  230  via the user computer terminal  110  for member registration; and an application registration method in which the virtual affiliated store management server  310  of the virtual affiliated store management server unit  300  is accessed via the mobile communication terminal  100  for member registration via the virtual card payment application installed on the mobile communication terminal  100 . Further, such a member registration method may include an application installation procedure and a member registration procedure. 
         [0101]    Since the application installation procedure is identical to that of a conventional mobile communication terminal, a detailed description thereof will be omitted. 
         [0102]    When a member registration procedure is described, the user accesses the virtual affiliated store management server unit  300  via the user terminal unit  1  (S 611 ). When the virtual affiliated store management server unit  300  is accessed, it may provide a webpage, which includes various types of information related to the self-payment service of the present invention and menus for affiliated store registration and personal member registration, to the user terminal unit  1 , or may activate the virtual card payment application installed in the mobile communication terminal  100 . 
         [0103]    When the user requests personal member subscription (registration) via the webpage or the activated virtual card payment application, the user terminal unit  1  transmits a personal member subscription request signal to the virtual affiliated store management server unit  300  (S 613 ). 
         [0104]    Then, the virtual affiliated store management server unit  300  provides a webpage including a personal member registration means having an identity authentication item to the user terminal unit  1 , or provides a registration means activation signal required to activate the registration means of the application (S 615 ). 
         [0105]    When the identity authentication item is selected and information required for identity authentication is input, the virtual affiliated store management server unit  300  performs identity authentication through the mobile communication company server  500  corresponding to the mobile communication terminal  100  of the user terminal unit  1  (S 616  and S 617 ). 
         [0106]    When identity authentication is performed, the virtual affiliated store management server unit  300  determines whether identity authentication has succeeded (S 619 ). If the identity authentication has failed, the server unit  300  sends an identity authentication failure notification message to the user terminal unit  1  (S 621 ). In contrast, if the identity authentication has succeeded, when a personal member registration request signal including personal member information input through the personal member registration means is received from the user terminal unit  1 , the server unit  300  stores the personal member information in the user DB  340  and then completes the member registration (S 625 ). The notification of completion of member registration is provided to the user terminal unit  1  (S 627 ). 
         [0107]    The method for allowing the user to register as a personal member to use the self-card payment service as shown in  FIG. 6  has been described. A method for allowing an affiliated store to register as a member as shown in  FIG. 7  will be described below. 
         [0108]      FIG. 7  is a flowchart showing a method for allowing an affiliated store to register as a member for self-card payment using a mobile communication terminal according to the present invention. 
         [0109]    First, an affiliated store manager accesses the web server  330  of the virtual affiliated store management server unit  300  through the affiliated store computer terminal  290  (S 711 ). In this case, the web server  330  may provide a webpage including a menu item enabling a virtual card payment affiliated store application to be installed. 
         [0110]    After accessing the web server, if the affiliated store manager selects the menu item enabling the virtual card payment affiliated store application to be installed, the affiliated store computer terminal  290  transmits a virtual card payment affiliated store application installation request signal, which requests the installation of the virtual card payment affiliated store application, to the web server  330  (S 713 ). 
         [0111]    Then, the web server  330  of the virtual affiliated store management server unit  300  provides a virtual card payment affiliated store application download webpage, which enables the virtual card payment affiliated store application to be downloaded, to the affiliated store computer terminal  290  (S 715 ). 
         [0112]    When the affiliated store manager enters card payment terminal information, including information such as the manufacturer and model name of the card payment terminal  200  used thereby, via the virtual card payment affiliated store application download webpage and then requests the downloading of the virtual card payment affiliated store application, the affiliated store computer terminal  290  transmits a virtual card payment affiliated store application download request signal, which includes card payment terminal information, to the web server  330  of the affiliated store management server unit  300  (S 717 ). 
         [0113]    Then, the web server  330  searches the application DB  360  for the installation program and the virtual card payment affiliated store application corresponding to the card payment terminal information of the card payment terminal  200 , and transmits the found installation program and virtual card payment affiliated store application to the affiliated store computer terminal  290  (S 719 ). 
         [0114]    Then, the affiliated store computer terminal  290  receives the installation program and the virtual card payment affiliated store application, installs and/or executes the installation program, and thereafter upgrades the card payment terminal  200  with the card payment affiliated store application via the installation program (S 721 ). Here, the card payment affiliated store application may be firmware. 
         [0115]    After the installation of the virtual card payment affiliated store application, the affiliated store manager clicks an affiliated store registration menu on the webpage provided by the web server  330  of the virtual affiliated store management server unit  300  through the affiliated store computer terminal  290 , and transmits an affiliated store registration request signal to the web server  330  (S 723 ). In this case, the affiliated store registration request signal includes affiliated store information, which includes the name, phone number, and card payment terminal identification information of the corresponding affiliated store, along with normal card affiliation documents. In this regard, the affiliated store must first have been authorized by all respective financial institutions, such as card companies and banks related to card payment. 
         [0116]    Then, the web server  330  of the virtual affiliated store management server unit  300  stores and registers the affiliated store information and affiliation documents in the affiliated store DB  330  (S 725 ), and thereafter allocates a unique identifier code for the self-card payment service of the affiliated store to the affiliated store card terminal  200 , either through the affiliated store computer terminal  290  or directly (S 729 ). The unique identifier code indicates that the corresponding payment is based on a self-card payment service, and may be attached to card payment terminal identification information. For example, when the card payment terminal identification information is 000-0000-0000, the unique identifier code XXX is attached thereto, and then resulting card payment terminal identification information may be 000-0000-0000-XXX. 
         [0117]      FIG. 8  is a flowchart showing a first embodiment of a self-card payment method using a mobile communication terminal according to the present invention. Hereinafter, the self-card payment method according to the present invention will be described with reference to  FIG. 8 . 
         [0118]    First, when a user who has subscribed to a self-card payment service according to the present invention and is purchasing goods, such as food or a product, requests self-payment from an affiliated store, an affiliated store manager, that is, a store owner, may enter a payment amount by clicking the key of the input unit  230  of the affiliated store card payment terminal  200  (S 811 ), enter the phone number of the mobile communication terminal  100  of the card user (S 813 ), and then input a self-payment menu key (S 814 ). 
         [0119]    After the self-card payment menu key has been input, the affiliated store card payment terminal  200  transmits a self-payment request signal, which includes card payment terminal identification information having the entered payment amount, the phone number of the mobile communication terminal  100 , and the unique self-card payment service identifier information of the affiliated store card payment terminal  200 , to the virtual affiliated store management server  310  of the virtual affiliated store management server unit  300  (S 815 ). 
         [0120]    The virtual affiliated store management server  310  determines, via the user DB  350 , whether the mobile communication terminal  100  is owned by a member that has subscribed to the self-card payment service, based on the phone number included in the self-payment request signal (S 817 ). If it is determined that the mobile communication terminal  100  is not owned by a member, the virtual affiliated store management server  310  transmits a non-member notification signal, which indicates that the user of the mobile communication terminal  100  corresponding to the phone number is not a member, to the card payment terminal  200  (S 821 ), whereas if it is determined that the mobile communication terminal  100  is owned by a member, the virtual affiliated store management server  310  generates virtual card terminal identification information for the card payment terminal  200  and allocates it to the mobile communication terminal  100  (S 823 ). 
         [0121]    After the allocation of the virtual card terminal identification information, the virtual affiliated store management server  310  transmits a bill including the virtual card terminal identification information to the mobile communication terminal  100  over the wired/wireless data communication network  150  (S 825 ). 
         [0122]    When the bill is received from the virtual affiliated store management server  310 , the mobile communication terminal  100  detects and stores the virtual card terminal identification information, and displays the bill and a message requesting the touching of the card on the display unit  40  (S 827 ). 
         [0123]    After the bill has been displayed, the mobile communication terminal  100  checks whether card information has been read via the card reader unit  50  (S 829 ). If card information is not read within a predetermined period of time, the mobile communication terminal  100  deletes the stored virtual card terminal identification information, and transmits a virtual card terminal identification information deletion request signal to the virtual affiliated store management server  310  (S 831 ). The virtual affiliated store management server  310  that receives the virtual card terminal identification information deletion request signal may delete the virtual card terminal identification information allocated to the mobile communication terminal  100 . 
         [0124]    In contrast, if it is determined that the card information has been read, the mobile communication terminal  100  transmits a card validity check request signal including the read card information to the virtual affiliated store management server  310  (S 833 ). 
         [0125]    The virtual affiliated store management server  310  that receives the card validity check request accesses the corresponding financial company server of the financial server unit  400  corresponding to the card information, checks the validity of the card (S 835 ), and then determines whether the card is valid (S 837 ). 
         [0126]    As a result of the card validity check, if the card is determined to be invalid, the virtual affiliated store management server  310  deletes the virtual card terminal identification information, regenerates virtual card terminal identification information (S 841 ), and transmits it to the mobile communication terminal  100  (S 843 ), whereas if there is no abnormality in the validity of the card, the virtual affiliated store management server  310  transmits a card validity authorization signal to the mobile communication terminal  100  (S 839 ). 
         [0127]    After the card validity check request has been transmitted, the validity of the card is checked and then virtual card terminal identification information is received again from the virtual affiliated store management server  310 , the mobile communication terminal  100  determines that the card is invalid, displays a card abnormality message, and re-displays the bill and a message requesting the touching of the card to cause the card information to be read again (S 827 ). 
         [0128]    However, when the card validity authorization information is received, the mobile communication terminal  100  displays a payment amount and a signature request screen (S 847 ), checks whether a signature has been entered (S 849 ), and if the signature has been entered, transmits a payment request signal, which includes a bill and the virtual card terminal identification information, to the virtual affiliated store management server  310 , wherein the bill contains the signature and the payment amount information (S 851 ). 
         [0129]    The virtual affiliated store management server unit  300  that receives the payment request signal transmits the payment request signal to the affiliated store card payment terminal  200 , to which the virtual card terminal identification information is allocated, according to a third embodiment of the present invention (S 853 ). 
         [0130]    The affiliated store card payment terminal  200  that receives the payment request signal performs a typical payment authorization procedure based on its on card payment terminal identification information and then processes payment (S 857 ), either when a confirmation command is input from the input unit  230  (S 855 ) or at the moment at which the payment request signal is received. 
         [0131]    When the payment based on the payment authorization procedure has been completed, the affiliated store card payment terminal  200  may receive a transaction record from the corresponding financial company of the financial server unit  400  and print it. In this case, the affiliated store card payment terminal  200  according to the present invention may be configured to provide transaction record data to the virtual affiliated store management server unit  300 . Further, the virtual affiliated store management server unit  300  that receives the transaction record data may be configured to transmit the transaction record data to the mobile communication terminal  100  through the virtual card payment application. 
         [0132]      FIG. 9  is a flowchart showing a second embodiment of a self-card payment method using a mobile communication terminal according to the present invention. Unlike the configuration of  FIG. 8 , in which the affiliated store card payment terminal  200  ultimately authorizes card payment, this configuration shows the case where the final payment request for self-card payment is made by the virtual affiliated store management server unit  300 . 
         [0133]    In  FIG. 9 , the same reference numerals are used to designate the same procedures as those of  FIG. 8 . 
         [0134]    In  FIG. 9 , when a payment request signal is received from the mobile communication terminal  100  (S 851 ), the virtual affiliated store management server unit  300  accesses the financial company server of the financial server unit  400  corresponding to the card information included in the payment request signal, performs a typical payment authorization procedure based on the card terminal identification information of the virtual affiliated store management server unit  300 , and then processes payment (S 861 ). 
         [0135]    After the authorization of payment has been completed, if transaction record data is received from the financial server unit  400 , the virtual affiliated store management server unit  300  transmits payment completion information including the transaction record data to the affiliated store card payment terminal and the mobile communication terminal  100  through the virtual card payment affiliated store application and the virtual card payment application, respectively (S 863  and S 865 ). 
         [0136]    The mobile communication terminal  100  and the affiliated store card payment terminal  200  that have received the payment completion information may display and show the transaction record data. 
         [0137]    Meanwhile, the present invention is not limited to the above-described typical preferable embodiments, and those skilled in the art will appreciate that various modifications, changes, substitutions, or additions are possible, without departing from the gist of the invention. The technical spirit of those modifications, changes, substitutions, or additions may be construed as being included in the present invention if the practice thereof belongs to the scope of the accompanying claims.
