Description:
BACKGROUND 
       [0001]    1. Field 
         [0002]    The present disclosure relates to gift certificated and more particularly to processing and using gift certificates in connection with credit cards, bank cards and/or financial accounts. 
         [0003]    2. Related Technology 
         [0004]    Gift certificates that general consumers have widely used are bearer securities with fixed amounts of money that can be exchanged with goods. The gift certificates have an advantage in that users of the gift certificates can purchase, at some appropriate time, a variety of goods dealt by gift certificate issuing stores to their tastes within the ranges of amounts printed on the gift certificates. Further, unrealized amounts of the gift certificates obtained through issuance of the gift certificates play a role as interest-free borrowings from the viewpoint of the gift certificate issuing stores, thereby favorably contributing to management of the gift certificate issuing stores and greatly contributing to rise of the prestige and rise of credit rating of the gift certificate issuing stores as well. Due to a variety of such advantages provided to both the gift certificate users and the gift certificate issuing stores, gift certificates are being issued and distributed by many enterprises in various fields such as department stores, bookstores and confectionery stores. As purchasable items get increased, the gift certificates are being widely given and taken as gifts among general consumers. As a result, a gift certificate market has grown rapidly in recent years. 
         [0005]    However, in spite of such advantages, the conventional gift certificates have many problems resulting from attributes of the gift certificates. That is, since the use of the conventional gift certificates is inevitably restricted only to gift certificate issuing stores and some affiliated stores, their distribution ranges are inevitably limited. Further, as most of the gift certificates are mainly purchased by cash, there is a problem in that purchase of the gift certificates through credit card transactions is limited in practice. In addition, there are problems in that it is impossible to identify use particulars thereof since the gift certificates can be used by bearers, and that amounts of money used for purchasing goods using the gift certificates cannot be properties for benefit of deductions and exemptions. 
         [0006]    In view of transactions in the gift certificates, the gift certificates have many problems. Since the transactions in the gift certificates necessarily always involve spot transactions, it is impossible to make on-line transactions and to expand transaction methods. Moreover, illegal distribution of the gift certificates through so called ‘card kkang,’ which is a kind of illegal card discount, has caused undesirable results opposing a tax policy of the government for intending to secure a variety of tax sources and to regulate hidden revenue. 
         [0007]    Further, since the conventional gift certificates have predetermined limit amounts of money, if the gift certificate users intend to purchase goods beyond the predetermined limit amounts of the gift certificates, the users cannot avoid inconvenience of additionally paying exceeded amounts of money in cash or with credit cards in addition to the gift certificates, which is considered as ‘duality in payment means.’ Moreover, there is inconvenience of refunding the remaining amounts after purchasing goods below the limit amounts of the gift certificates, and there is also a problem in that disputes between the gift certificate issuing stores and the users frequently arise due to cash refund requests. 
         [0008]    Recently, use of credit cards has dramatically increased given many advantages of credit card transactions. Accordingly, attempts to develop new gift certificates using credit cards are continuously being made by the credit card industry in order to solve the aforementioned problems with the conventional gift certificate system and in order to promote credit card transactions. Korean Patent Application No. 2000-67106 discloses “Method of operating card gift certificate based on credit card system,” wherein a gift certificate is manufactured in the form of a credit card according to order information provided by a credit card member and a third person who has received the card gift certificate manufactured in this manner freely purchases goods or services at member stores affiliated with a relevant credit card company within an issued amount of money in the card gift certificate. However, since the method of operating the card gift certificate disclosed in the above patent application requires issuance of an additional card besides the credit card, it inevitably causes resistance of rejecting the use of the card gift certificate by some member stores affiliated with the credit card company. Furthermore, the method still has a disadvantage in that use particulars of the card gift certificate are difficult to identify since any bearer thereof can use the card gift certificate, and that benefit of deductions and exemptions cannot be obtained. In addition, there is a problem in that it is still impossible to avoid the duality in payment means in which a purchasing amount exceeding a predetermined limit amount of the gift certificate should be paid by using another payment means except the card gift certificate. 
         [0009]    The foregoing discussion in this section is to provide background information only and does not constitute an admission of prior art.

         [0064]    To receive the request for use of the gift certificate, the credit card gift certificate server  120  receives the information on the request from the user&#39;s terminal  110  through the communication network. Alternatively, in a case where the credit card user directly visits one of agents operated by Credit Card Gift Certificate Co., Ltd. or the credit card companies or makes the request to the agent by telephone, the gift certificate server  120  can receive the request from an agent&#39;s terminal. Further, even in a case where the credit card user purchase goods by a credit card at a member store affiliated with a relevant credit card company, the gift certificate server  120  can receive the request from the agent&#39;s terminal when the user presents the credit card gift certificate of an embodiment to the member store. 
         [0065]    To more strictly determine whether a credit card gift certificate is lawful, the user may be asked to additionally input an amount of money of the gift certificate or a gift certificate password as the information on the request for use thereof in addition to the gift certificate authentication number. The gift certificate server  120  identifies the credit card gift certificate carried by the credit card user based on the information on the request for use of the gift certificate received from the user. 
         [0066]    In step S 110 , the gift certificate server  120  verifies whether the gift certificate is usable in response to the request for use of the gift certificate received in step S 100 . The step of verifying whether the gift certificate is usable includes the step of determining whether the gift certificate is lawful by using the information received from the credit card user upon receipt of the request. The determination of whether the gift certificate is lawful is to identify a forged gift certificate with a fraud authentication number or a gift certificate falsely requested due to an error of the credit card user. This determination can be achieved in such a manner that the credit card gift certificate server  120  gains access to the gift certificate issuing information DB  140  and compares the gift certificate authentication number  141  stored in the DB  140  with the gift certificate authentication number received from the credit card user. As another embodiment of the present invention, even in a case where the gift certificate issuing information such as the amount of money of the gift certificate in addition to the gift certificate authentication number is received in step S 100 , such information can be used for determining whether the gift certificate is lawful through comparison thereof with the information stored in the gift certificate issuing information DB  140 . 
         [0067]    As a further embodiment of the present invention, the step of verifying whether the gift certificate is usable may include the step of determining whether the credit card is usable. Such a step is to prevent use of a gift certificate by a person with bad credit rating or use of a gift certificate based on credit card transactions in which a valid date of a credit card has expired and normal transactions cannot be made. This determination can be achieved in such a manner that the credit card gift certificate server  120  searches the valid dates of credit cards  154  or credit card transaction restriction information  156  stored in the credit card information DB  150  by using the credit card identification number  151  received from the credit card user in step S 100 . As a still further embodiment regarding the determination of whether a lawful credit card user can utilize a credit card, step S 100  may include the step of comparing, by the credit card gift certificate server  120 , the credit card identification number  151  and the credit card password  157  received from the credit card user with the information stored in the credit card information DB  150 . 
         [0068]    If it is determined in step S 110  that the gift certificate is usable, the limit of the gift certificate corresponding to the amount of money of the gift certificate is configured in the credit card of the credit card user in step S 120 . 
         [0069]    In most of credit card transactions presently made, the credit card transaction limit consists of a combination of one payment limit, installment limit, cash service limit and the like. A credit card user is restricted in his/her credit card transactions by the above limits. Generally, such limits are determined through appraisal of credit rating of the credit card user by the credit card company based on transaction history of the credit card user. 
         [0070]    Due to the configuration of the limit of the gift certificate according to an embodiment, a new credit card transaction limit made by adding the limit of the gift certificate to the existing credit card transaction limit of the credit card user is established, and the credit card user can make credit card transactions additionally as much as the added transaction limit corresponding to the amount of money of the gift certificate. 
         [0071]    To configure the limit of the gift certificate, the gift certificate server  120  can directly gain access to the credit card information DB  150  and update the credit card transaction limit information  153  with respect to a credit card identification number of the user. As a still further embodiment, the gift certificate server  120  can transmit a request for configuration of the limit of the gift certificate to the credit card company&#39;s server  130 , which can update the credit card transaction limit information  153  in the credit card information DB  150  in response to the request for configuration of the limit of the gift certificate. 
         [0072]    The procedure for additionally configuring, by the bearer of the credit card gift certificate, the limit of the credit card gift certificate corresponding to the amount of money of the gift certificate to his/her own credit card has been described. Now, a procedure for making credit card transactions and payment using the configured limit of the gift certificate by the credit card user will be described in detail. 
         [0073]    As described in the foregoing disclosure, operating and processing the credit card gift certificate according to embodiments of the present invention, the existing credit card owned by the credit card user can be utilized as it is without issuing an additional credit card, and the procedures performed among the credit card user, the member store and the credit card company in credit card transactions made at the member store are almost the same as conventional procedures for credit card transactions. That is, the member store requests the credit card company to approve the transactions using the credit card presented by the credit card user, and the credit card user signs a sales slip after receipt of approval determination from the credit card company. Then, information related to such credit card transactions is stored as the credit card transaction information  152  in the credit card information DB  150 . The credit card company&#39;s server  130  gains access to the credit card transaction information  152  stored in the credit card information DB  150 , prints use particulars of the credit card on a credit card bill based on such information and notifies the credit card user of the credit card bill. Then, the credit card user makes payment for the notified amount on a predetermined payment due date. The member store collects sales slips and requests the credit card company to pay sales amount. The credit card company subtracts a predetermined amount of service fee from the payment amount received from the credit card user and then gives the difference to the member store. 
         [0074]      FIGS. 6   a  and  6   b  show general examples of a credit card bill notified to a credit card user in conventional credit card transactions.  FIG. 6   a  shows billing particulars of amounts of money paid by the credit card and  FIG. 6   b  shows detailed use particulars of the credit card. 
         [0075]      FIGS. 7   a  and  7   b  show examples of a credit card bill notified to the credit card user in the credit card transactions in which the limit of the gift certificate is additionally configured to the credit card according to embodiments of the present invention. The credit card company&#39;s server  130  generally gains access to the credit card transaction information  152  stored in the credit card information DB  150  to prepare the credit card bill and additionally gains access to the credit card transaction limit information  153  to determine the configured limit of the gift certificate and to prepare the credit card bill by reflecting the configured limit thereon. That is, in a case where an amount of money paid by the credit card of the user obtained from the credit card information DB exceeds the limit of the gift certificate, the credit card company&#39;s server  130  computes an amount of money to be paid by the credit card user by subtracting the limit of the gift certificate from the amount paid by the credit card. Then, the credit card company&#39;s server  130  resets the limit of the gift certificate to ‘0’ Korean won (KRW) and stores it in the credit card information DB  150 . If an amount of money paid by the credit card is within the limit of the gift certificate, the credit card company&#39;s server  130  sets the residual limit of the gift certificate obtained by subtracting a used amount of money from the original limit of the gift certificate as a new limit of the gift certificate, and stores the new limit of the gift certificate in the credit card information DB  150 . An amount of money corresponding to the residual limit of the gift certificate can be refunded according to a predetermined procedure and within a predetermined period of time when the user requests refund of the amount. If there is no request for refund, the residual limit of the gift certificate is again set as a new limit of the gift certificate and can be used in future credit card transactions in the next month or later on. 
         [0076]    As shown in  FIGS. 6   a  to  7   b , both use particulars of a credit card owned by a credit card user are the same. However, since the limit of a gift certificate of 500,000 Korean won is additionally configured in  FIGS. 7   a  and  7   b , an amount of money obtained by subtracting 500,000 Korean won from a used amount of money becomes an amount of money that should be actually paid by the credit card user. 
         [0077]    As one embodiment of the present invention, in a case where a credit card user makes credit card transactions using a credit card in which the limit of a gift certificate is additionally configured, an amount up to the limit of the gift certificate is first used in payment, and an amount up to one payment limit is then additionally used in payment for a transaction amount exceeding the limit of the gift certificate. According to such an embodiment, the limit of the gift certificate is updated depending on an amount paid by the credit card every approval of credit card transactions. That is, the credit card company&#39;s server  130  gains access to the limit of the gift certificate of the credit card transaction limit information  153 , updates the changed limit of the gift certificate obtained by subtracting an amount paid by the credit card from the original limit of the gift certificate as a new limit of the gift certificate, and stores again the new limit of the gift certificate in the credit card transaction limit information  153 . If an amount paid by the credit card exceeds the current limit of the gift certificate, the credit card company&#39;s server  130  updates the limit of the gift certificate of the credit card transaction limit information  153  as ‘0’ Korean won, and causes one payment limit to be used in paying the difference. Further, the credit card company&#39;s server  130  determines whether credit card transactions are performed by using the limit of the gift certificate or one payment limit, and stores the determination results in the credit card transaction information  152  so that the information may be used for preparing a credit card bill. 
         [0078]      FIG. 8  shows a credit card sales slip in conventional credit card transactions. As shown in  FIG. 8 , ‘sales classification’ indicated on the credit card sales slip shows whether the credit card transactions are ‘one payment’ or ‘installment’ transactions. 
         [0079]      FIG. 9  shows a credit card sales slip in the method for operating the credit card gift certificate according to an embodiment of the present invention. As shown in  FIG. 9 , the credit card company&#39;s server  130  marks ‘gift certificate’ on the sales classification section of the credit card sales slip in a case where credit card transactions are approved within the limit of the gift certificate. That is, upon approval of credit card transactions, the credit card company&#39;s server  130  gains access to the limit of the gift certificate in the credit card transaction limit information  153 , approves the credit card transactions by causing the limit of the gift certificate or one payment to be used in consideration of the limit of the gift certificate, and then marks the payment results on the ‘sales classification’ section. Moreover, in the method for operating the credit card gift certificate shown in  FIG. 9 , a residual limit of the gift certificate can be disclosed on the credit card sales slip. As illustrated in  FIG. 9 , the credit card company&#39;s server  130  marks the limit of the gift certificate updated upon approval of credit card transactions on the credit card sales slip, as the residual limit of the gift certificate. 
         [0080]    As described above, the credit card user can recognize from the credit card sales slip in the credit card transactions that the approval of the credit card transactions is made within the limit of the credit card gift certificate and can also immediately find the current residual limit of the gift certificate. As another embodiment, the credit card user may inquire the credit card company or Credit Card Gift Certificate Co., Ltd. of particulars of credit card transactions and the residual limit of the gift certificate by making a phone call thereto or through a communication network such as Internet. 
         [0081]    The credit card transaction method using the aforementioned credit card gift certificate can also be applied to a case where a credit card is a type of “account transaction card.” The “account transaction card” means a credit card of which a transaction limit is “0” Korean won. In transactions using the account transaction card, contrary to general credit card transactions, transaction approval is made only after confirming that the balance in a relevant bank account associated with the credit card is above an amount to be paid by the credit card when a member store requests the transaction approval. The next procedures are the same as general credit cards. When the credit card gift certificate in embodiments of the present invention is applied to the account transaction card, the credit card gift certificate server  120  or the credit card company&#39;s server  130  newly generates the credit card transaction limit of the account transaction card corresponding to an amount of money of a gift certificate so that the newly generated credit card transaction limit can be used in transactions using the account transaction card. 
         [0082]      FIG. 10  is a flowchart illustrating a further embodiment in which an amount of money of a gift certificate is configured as the gift certificate balance in a payment account for a credit card so that it can be used in credit card transactions. That is, instead of configuring the amount of money of the gift certificate as the limit of the gift certificate in the credit card as shown in  FIG. 5 , the amount of money of the gift certificate is configured as the virtual balance of “gift certificate balance” in the payment account for the credit card of the credit card user. An amount obtained by subtracting the balance from an amount paid by the credit card can be calculated as a payment amount to be paid by the credit card user upon preparation of a credit card bill, and the user is then notified of the calculated amount. 
         [0083]    The processes in steps S 100  and S 110  in the embodiment shown in  FIG. 5  may be directly applied to step S 200  and  210 . In step S 220 , the gift certificate balance corresponding to the amount of money of the gift certificate is configured in the payment account for the credit card. To configure the gift certificate balance, the gift certificate server  120  may configure the gift certificate balance in the payment account by directly gaining access to the credit card information DB  150  and adding the gift certificate balance to the credit card account information  158  corresponding to the credit card identification number of the credit card user. Alternatively, the gift certificate server  120  may request the credit card company&#39;s server  130  to configure the gift certificate balance, and the credit card company&#39;s server  130  may update the credit card account information  158  in the credit card information DB  150  in response to the request for configuration of the gift certificate balance. In a case where the gift certificate balance is configured in the credit card as much as the amount of money of the gift certificate according to the embodiment shown in  FIG. 10 , the method further comprises the step of determining an amount obtained by subtracting the balance from an amount paid by the credit card, as a payment amount to be paid by the user when notifying the user of a credit card bill. That is, the credit card company&#39;s server  130  generally gains access to the credit card transaction information  152  stored in the credit card information DB  150  to prepare the credit card bill and additionally gains access to the credit card account information  158  to determine how much the configured gift certificate balance is and to prepare the credit card bill by reflecting the configured gift certificate balance thereon. 
         [0084]    The embodiment in which the gift certificate balance is additionally generated in the payment account for the credit card instead of configuring the limit of the gift certificate can be applied to the case where the credit card is the account transaction card. That is, in transactions using the account transaction card, transaction approval is made after an amount paid by the credit card is compared with the balance of the payment account to which the gift certificate balance is added. 
         [0085]    Although the embodiment described in connection with  FIG. 10  has exemplified the configuration of the gift certificate balance in the payment account for the credit card or account transaction card, the gift certificate balance may also be identically configured in other virtual accounts designated by the credit card user as well as the payment account of the credit card user. Further, this embodiment may be directly applied to the processes of paying an amount paid by the credit card and preparing a credit card bill. 
         [0086]    Although only certain embodiments of operating the gift certificate using the credit card has been described, it will be apparent to those skilled in the art that various changes and modifications can be made to the disclosed embodiments of the present invention. 
         [0087]    According to the present invention, it can be understood from the foregoing embodiments that the operation of the credit card gift certificate can also be applied to bearer card transactions. That is, a bearer of the credit card gift certificate in embodiments of the present invention can configure an amount corresponding to an amount of money of the gift certificate as the limit of the gift certificate in his/her own bearer card and then make bearer card transactions within the configured limit. Even after an amount corresponding to the limit of the gift certificate is completely used, the limit of a new gift certificate is additionally configured in the bearer card so that the bearer card can be recharged repeatedly and used for card transactions. 
         [0088]    In addition, embodiments of the present invention further relate to computer readable media that include program instructions for performing various computer-implemented operations. The media may also include, alone or in combination with the program instructions, data files, data structures, tables, and the like. The media and program instructions may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well known and available to those having skill in the computer software arts. Examples of computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as floptical disks; and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM) and random access memory (RAM). The media may also be a transmission medium such as optical or metallic lines, wave guides, etc. including a carrier wave transmitting signals specifying the program instructions, data structures, etc. Examples of program instructions include both machine code, such as produced by a compiler, and files containing higher level code that may be executed by the computer using an interpreter. 
         [0089]      FIG. 11  is a block diagram showing an inner configuration of a typical computer system capable of being used the method for operating the credit card gift certificate according to an embodiment of the present invention. 
         [0090]    The computer system  1100  includes any number of processors  1110  (also referred to as central processing units, or CPUs) that are coupled to storage devices including primary storage  1120  (typically a random access memory, or “RAM”), primary storage  1130  (typically a read only memory, or “ROM”). As is well known in the art, primary storage  1120  acts to transfer data and instructions uni-directionally to the CPU and primary storage  1120  is used typically to transfer data and instructions in a bi-directional manner. Both of these primary storage devices may include any suitable type of the computer-readable media described above. A mass storage device  1140  is also coupled bi-directionally to CPU  1110  and provides additional data storage capacity and may include any of the computer-readable media described above. The mass storage device  1140  may be used to store programs, data and the like and is typically a secondary storage medium such as a hard disk that is slower than primary storage. A specific mass storage device such as a CD-ROM  1160  may also pass data uni-directionally to the CPU. 
         [0091]    Processor  1110  is also coupled to an interface  1150  that includes one or more input/output devices such as such as video monitors, track balls, mice, keyboards, microphones, touch-sensitive displays, transducer card readers, magnetic or paper tape readers, tablets, styluses, voice or handwriting recognizers, or other well-known input devices such as, of course, other computers. Finally, processor  1110  optionally may be coupled to a computer or telecommunications network using a network connection as shown generally at  1170 . With such a network connection, it is contemplated that the CPU might receive information from the network, or might output information to the network in the course of performing the above-described method steps. The above-described devices and materials will be familiar to those of skill in the computer hardware and software arts. The hardware elements described above may be configured (usually temporarily) to act as one or more software modules for performing the operations according to embodiments of this invention. 
         [0092]    According to the method for operating the credit card gift certificate in embodiments of the present invention described above, a user of a gift certificate can arbitrarily select one among credit cards and thus use the gift certificate at any one of member stores affiliated with a plurality of credit card companies. Therefore, the gift certificate can be used in a state where a distribution range of the gift certificate is expanded and limitations on purchasable items are remarkably reduced. 
         [0093]    Further, according to the method for operating the credit card gift certificate in embodiments of the present invention, the existing credit card can be used as it is without issuing an additional credit card. Thus, the problem of rejection of use of the gift certificate by some member stores is solved, and time and costs required for issuing an additional new credit card can be reduced. 
         [0094]    According to the method for operating the credit card gift certificate in embodiments of the present invention, since the gift certificate is used based on credit card transactions, there is an advantage in that use particulars of the gift certificate can be easily confirmed through a credit card bill or by inquiring a credit card company of use particulars thereof. Due to such an advantage, the credit card gift certificate in embodiments of the present invention can be used as a card for pocket money of his/her child. That is, a credit card of which transaction limit is “0” Korean won is issued in the name of one&#39;s child who is a person under age and the limit of the gift certificate in embodiments of the present invention is configured as pocket money in the credit card of the child. Then, there is another advantage in that parents can always check pocket money expenditure particulars of their child, and safe credit card transactions can be extended to persons under age. According to the method for operating the credit card gift certificate in embodiments of the present invention based on credit card transactions, even when the credit card is lost, the residual limit of the gift certificate can be configured again in a newly issued credit card. Furthermore, there is an advantage in that damage compensation can be made for an amount illegally paid by the third party during a period of loss of the credit card. Additionally, it is possible to provide a variety of additional services according to credit card transactions, e.g., accumulation of points corresponding to an amount paid by the credit card, a credit card lottery service, etc. 
         [0095]    Further, according to the method for operating the credit card gift certificate in embodiments of the present invention, there is an advantage in that a transaction amount of a credit card user is increased as much as the limit of the gift certificate. 
         [0096]    Furthermore, according to the method for operating the credit card gift certificate in embodiments of the present invention, there is an advantage in that a payment means is simplified even when purchase exceeding the limit of the gift certificate is made. 
         [0097]    Moreover, according to the method for operating the credit card gift certificate in embodiments of the present invention, there is an advantage in that a credit card user can easily recognize the residual limit of the gift certificate limit through a credit card sales slip.
