Description:
TECHNICAL FIELD  
       [0001]     The present invention relates to the credit card industry in which, for over a generation, the users and owners of credit cards are able to complete purchases and draw cash at hundreds of thousands of networked sale point terminals and ATM (automatic teller machine) terminals throughout the world.  
       BACKGROUND OF RELATED ART  
       [0002]     Computers and their application programs are used in all aspects of business, industry and academic endeavors. The computer industry has been a force for bringing about great increases in business and industrial productivity. Almost every week seems to bring computer industry advances that promise even further increases in productivity. These advances offer to drive down business and industry costs and increase efficiency, as well as increasing productivity. In addition, the cost of “computer power” continues to drop as a result of rapid advances in computer related technologies.  
         [0003]     Despite all of these advances in computer power availability and cost, there still remains a reluctance in the credit card industry towards rapid technological advance. While the numbers of credit card owners and users have been accelerating over the years, technological innovation towards an ultimate primarily electronic consumer non-cash and non-check purchasing and payment system has been conservative. This, of course, has been limited by industry concerns about abuse and fraud on the part of some card holders.  
         [0004]     One area of potential industry concern is on the ability of the credit owners, i.e. those responsible for control and payment, to limit credit card abuse. The present invention provides an implementation that enables the owner of the credit card to limit its use and, consequently, possible abuses.  
       SUMMARY OF THE PRESENT INVENTION  
       [0005]     The present invention provides an implementation for reducing the possibilities for credit card abuse. In this electronics age where a great many purchases and like transactions are diverse and decentralized, it is necessary for the owner of the credit cards to empower employees or other family members to use the credit card, i.e. the other&#39;s version of the owned credit card. However, there are often circumstances necessitating limitations on credit cards. It is known for the owner of the credit card to put a monetary limitation or cap on credit cards issued to employees or children of the card owner.  
         [0006]     Beyond that, the present invention has recognized that there are additional limitations that may be put on credit cards. In the case of a family credit card, it has become customary for the college student to receive a card with a spending level cap. However, now, even high school and elementary school may be given supplemental credit cards for their school and miscellaneous expenses. Of course, with children the parents will be interested in preventing purchases of substance abuse products and pornography, particularly in light of the ease with which credit card purchases may be made over the World Wide Web (Web).  
         [0007]     Accordingly, the present invention provides an implementation enabling an owner of a charge card to limit purchases made with said charge card comprising means enabling the owner of a charge card to limit purchases made with the charge card to purchases of either owner defined types of goods and/or owner defined geographical areas, and prohibiting purchases made with the charge card other than purchases within these limitations as defined by the card owner. The owner will be enabled to limit the purchases to particular goods or to particular sales establishments. Also, the charge card with limitation will generally be a secondary charge card issued to either a member in the family of the owner or an employee of the owner.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0015]     Referring to  FIG. 1 , there is provided a general illustrative embodiment of a banking transaction network for processing credit card transactions. The operations of such standard networks are well known and the specific operations of such networks need not be described in detail to support the present invention. Credit card terminals  11 ,  13  and  17  on the network respectively receive credit cards  14 ,  16  and  15 . Of course, the cards need not be inserted in receiving slots; the numbers of the cards may be entered by keying, e.g. Web credit card transactions. The transactions are transmitted over the network  10  usually via appropriate network servers (not shown). The transactions are submitted to the credit card owners bank  19  via network server  18 . All information related to the transactions are stored in the bank&#39;s database  35  that also stores all appropriate information related to the credit card owner. When the owner of the credit card wishes a secondary credit card for a family member or employee with limitations, the owner accesses the network through any convenient data entry terminal  37  connected to network  10  via an appropriate server  36 . The data limiting the usage of the secondary credit card is solicited, as will be described hereinafter with respect to  FIGS. 3 and 4 . The solicited data limiting the credit card usage is then transmitted via the network to bank  19  where it is available through credit database  35 .  
         [0016]     Referring now to  FIG. 2 , a typical data processing terminal is shown that may function as the user data entry network terminal  37 , servers  36  and  18 . A Central Processing Unit (CPU)  22 , such as one of the PC microprocessors or workstations, e.g. RISC System/6000™ (RS/6000) series available from International Business Machines Corporation (IBM), is provided and interconnected to various other components by system bus  12 . An operating system  21  runs on CPU  22 , provides control and is used to coordinate the function of the various components of  FIG. 2 . Operating system  21  may be one of the commercially available operating systems such as the AIX 6000™ operating system available from IBM; Microsoft&#39;s Windows98™ or WindowsNT™, as well as UNIX and other IBM AIX operating systems. Application programs  20 , controlled by the system, are moved into and out of the main memory, Random Access Memory (RAM)  24 . These programs include the programs and routines of the present invention for prompting the credit card owner through interactive dialog to provide the limitations on a secondary credit card as to the type of goods establishments in which the credit card may be used and for limiting the geographical area in which the credit card may be used. Read Only Memory (ROM)  26  is connected to CPU  22  via bus  25  and includes the Basic Input/Output System (BIOS) that controls the basic computer functions. RAM  24 , I/O adapter  28  and communications adapter  40  are also interconnected to system bus  25 . I/O adapter  28  communicates with the disk storage device  30 . Communications adapter  40  interconnects bus  25  with the appropriate outside network enabling the data processing system to communicate, as respectively described above, through the Web or Internet. I/O devices are also connected to system bus  25  via user interface adapter  32  and display adapter  29 . Mouse  27  is interconnected to bus  25  through user interface adapter  32 . Display adapter  36  supports monitor  38 . The display adapter and monitor may be eliminated in the network servers without any display I/O functions.  
         [0017]     With reference to  FIG. 3 , a data entry display terminal is shown, such as display terminal  37 ,  FIG. 1 , on which data may be entered through an interactive dialog that may be used to geographically limit use of a secondary credit card. The user has called upon the appropriate program and has identified and verified the credit card owner and the secondary card user  56 . The owner is prompted with an appropriate map  55  showing the geographical zones 1 through 13 for “River City” and has been prompted via menu  51  to select the type of limits that the owner wishes to add to the secondary card. The owner has already interactively selected two zones  54  from menu  53 . As a result, the use of the secondary credit has been limited to stores and like establishments within zones “5 and 8”.  
         [0018]     The  FIG. 4  display on which data may be entered through an interactive dialog that may be used to limit the use of a secondary credit card selected types of goods or establishments selling such goods. The user has called upon the appropriate program and has identified and verified the credit card owner and the secondary card user  56 . The owner has been first prompted via menu  51  to select the type of limits that the owner wishes to add to the secondary card. Here the owner has selected category  57 , types of products. As a result, the user has been prompted via menu  53  to select the type of establishment and has selected: auto fuel and service; food markets; clothing; and movie theaters. As a result, the secondary credit card users are limited to clothing, movies, food and auto fuel and service. Secondary users are, thus, limited to the items from the four categories selected from stores in such categories.  
         [0019]     Now, with reference to the programming shown in  FIG. 5 , the program of the present invention is set up. In a credit card transaction network including tracking, processing and billing, there is provided an interactive display user data entry program for enabling an account owner to change limits on owned credit cards, step  71 . This includes the provision of display interface dialogues for prompting the card owner to select to establish or change geographic and/or product/establishment limits on the credit card, step  72 . In order to create the interface for selecting geography, there is provided on the interactive display, a map broken into geographic sub-areas together with a series of prompts to enable the user to select the geographic area in which the credit card is to be valid, step  73 . Then, in order to create the interface for selecting types of goods limitations, there is provided on the interactive display, a list of numbered goods together with a series of prompts to enable the user to select the numbered goods and/or establishments selling such goods in which the credit card is to be valid, step  74 , together with a series of prompts to enable the user to select the goods and or establishments in which the credit card is to be valid. Also, step  75 , the owner is enabled to provide input to specially prohibit the use of the credit card in named establishments.  
         [0020]     Now, with reference to the flowchart of  FIG. 6 , a simplified illustrative run of the process set up in  FIG. 5  will be described. First, a determination is made as to whether the card owner has requested a change in the limitations in a credit card, step  80 . If Yes, a dialog window is displayed that offers to change the product or geography limits of the card, step  81 . Then, step  82 , a determination is made as to whether the owner has selected to make a change in the geography limitations of the card. If Yes, then, step  89 , there is displayed a map of area zones and the user is requested to select the zones in which the card is to be operable. The user then selects the zones, step  90 . The zones of operability are stored in association with the controlling bank, step  91 . The credit card will then be limited to use in the selected zones, step  92 .  
         [0021]     On the other hand, if the decision from step  82  had been No, a further decision is made, step  83 , as to whether the user has selected limitations relating to goods and services for which the credit card may be used. If Yes, step  84 , an appropriate list of types of goods is displayed and the card owner selects from the list the goods and services that may be purchased with the card, step  85 . The selected goods and services are stored in association with the controlling bank, step  86 . The card will then be limited to be used only for the purchase of the selected goods and services, step  87 . Next or after step  92 , a decision may conveniently be made as to whether the selection session is over, step  88 . If Yes, the session is exited. If No, the session is returned via branch “A” to initial step  80 .  
         [0022]     It should be noted that the programs covered by the present invention may be stored outside of the present computer systems until they are required. The program instructions may be stored in another readable medium, e.g. in a disk drive associated with the desktop computer or in a removable memory such as an optical disk for use in a CD ROM computer input or in a floppy disk for use in a floppy disk drive computer input. Further, the program instructions may be stored in the memory of another computer prior to use in the system of the present invention and transmitted over a Local Area Network (LAN) or a Wide Area Network (WAN), such as the Internet, when required by the user of the present invention. One skilled in the art should appreciate that the processes controlling the present invention are capable of being distributed in computer readable media of a variety of forms.  
         [0023]     Although certain preferred embodiments have been shown and described, it will be understood that many changes and modifications may be made therein without departing from the scope and intent of the appended claims.
