     FIELD OF THE INVENTION 
     The invention relates generally to computer systems for completing monetary transactions, and in particular, to a computer interface for providing access to a plurality of transaction payment networks. 
     BACKGROUND OF THE INVENTION 
     There exist a number of domestic and international payment networks available to facilitate the completion of monetary transactions. An individual payment network allows the user to affect a payment to individuals and/or corporations through the banking system. For example, the Federal Reserve Bank&#39;s Fedwire system is a payment network that allows users to transfer funds via the United States Federal Reserve Bank network. Other such payment networks include the Automated Clearing House (&#34;ACH&#34;) payment network, the New York Clearing House Interbank Payment System (&#34;CHIPS&#34;) and the Society for Worldwide Interbank Financial Telecommunication System (&#34;SWIFT&#34;). 
     In the initiation of payments and transfers between various entities, certain banks have provided access to the various payment networks to their customers. Accordingly, a customer can choose a preferred method of payment to complete a transaction depending on the nature of the transaction and the location of the entities involved. Some transactions may need to be completed within a definite time frame, such as twenty-four hours, and thus only a specific or limited number of payment networks may be employed to complete the transaction in the time required. Further, certain payment networks are more convenient or efficient than others depending on whether the transaction must be completed nationally or internationally. 
     To facilitate the use of such payment networks, banks have provided various data processing products to their customer base. Employing a data communications network and various types of computers monetary transactions can be completed quickly and safely without the need for significant bank intervention. Banks have, therefore, provided access to their customers to individual payment networks through the use of mainframe and personal computers, and local area networks or other forms of communication networks. A customer subscribing to one of these products would thus have access to a specific payment network to complete a certain type of payment transaction. Such customers typically include corporations, which employ personal computers or the like to communicate with the payment network subscribed to. 
     Over the years, therefore, a plurality of differing and sometimes incompatible payment network interfaces have been developed. Due to the differing nature of the various national and international payment networks, customers who subscribe to several network interfaces need to learn the proper protocol with which to access each system. Where many payment transactions need to be completed on a daily basis using various payment networks, the differing protocols for each can be confusing and difficult to master. Moreover, since the interface systems and the networks themselves include differing architectures, several forms of computer hardware are required to communicate with the host of payment networks available. This requires that a customer purchase or lease sometimes redundant computer hardware to communicate with differing systems. In addition to the increase in cost, such hardware also takes up valuable space. 
     What is lacking, therefore, is a single user interface that would allow customers to communicate with any of the payment networks. Such an interface would provide access to any or all of the available payment networks employing a minimal amount of hardware. In addition, such an interface would use a common protocol to initiate payment transactions over the various payment networks, thus eliminating the need to learn the protocol employed by each and every differing network. Preferably, such an interface would provide access to all of the payment networks through a single user interface appearing on a computer display terminal. 
     It is, therefore, an objective of the invention to provide a single display interface to initiate and complete monetary transfers over any of a plurality of payment networks. 
     It is also an objective of the present invention to provide access to the various payment networks employing a protocol that is common to initiate transactions over all networks. 
     It is further an objective of the invention to provide access to the various payment networks through a single transaction entry screen. 
     SUMMARY OF THE INVENTION 
     In view of the above, there is provided a system for providing access to a plurality of payment networks. The system includes a display for displaying a single transaction entry screen comprising a plurality of data input fields. Each data input field prompts for and displays data applicable to the plurality of payment network. Input means are provided to supply the data relevant to a particular transaction. Selection means are also provided to select one of the plurality of payment networks to be employed with the transaction and to generate a signal indicating the payment network selected. This signal is received by interface logic to interface to and complete the transaction employing the particular payment network selected. 
     In one presently preferred embodiment of the invention, a central computer is employed to receive signals from a remote computer, where each signal represents a particular transaction and a particular payment network to be employed with the transaction. A transaction entry screen having data input fields common to each payment network is displayed on a display coupled to the remote computer. In the preferred embodiment, a modem is employed to couple the central computer to the remote computer. 
     In another aspect of the invention, a method for providing access to a plurality of payment networks is provided. The method includes presenting an operator with a display having a single transaction entry screen comprising a plurality of data input fields. Each field prompts for and displays data applicable to the plurality of payment networks. An input device is employed, coupled to this display, for inputting the data relevant to a particular transaction. With the input device, a user also enters a selection of the desired payment network to be employed with the transaction. A signal is generated from the input device representing the payment network selected. This signal is received by interface logic employed to interface with and complete the transaction over the particular payment network selected. 
     The invention thus combines on a single display an operator interface common to the plurality of payment networks. Providing the customer with a display displaying a single transaction entry screen eliminates the need for redundant computer equipment and the need to learn and employ differing protocols for each payment network. According to the invention, the single transaction entry screen allows the user to initiate a payment over any of the payment networks. Combining access to all of the various payment networks in a common product also eliminates the need to service, maintain and support a plurality of differing information processing products. 
     These and other advantages will be apparent on consideration of the following detailed description of the preferred embodiments of the invention, taken in conjunction with the appended drawings.

     DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS 
     Referring now to the drawings, where like elements receive like reference numerals throughout, a block diagram of a system 10 for providing access to a plurality of payment networks is shown in FIG. 1. In the preferred embodiment of the system 10, a central computer 12 is provided to communicate with any one of a plurality of payment networks. Examples of such payment networks employed in a preferred embodiment of the invention include the Federal Reserve Bank Fedwire network 16, the ACH network 18, and the SWIFT network 20. Also shown in FIG. 1, the networks can be employed to complete transactions between the bank housing the central computer 12 and other regional, affiliated or branch banks 19. Thus, the SWIFT network 20 can be used to communicate transactions through a branch bank to another payment network such as the CHIPS network 21. 
     As those skilled in the art will appreciate, the payment networks illustrated in FIG. 1 are provided only by way of example, and any number of the available payment networks or systems can be employed with the invention without departing from its spirit or essential scope. Examples of such further payment networks and systems include various settlement networks in foreign countries and networks allowing for customer drawdowns from their own accounts. 
     To communicate with the plurality of payment networks, a network interface 22 is provided between the central computer 12 and the payment networks themselves. The network interface 22 can comprise a variety of communications and information transfer techniques. The network interface 22 can even comprise differing interfaces as dictated by each particular payment network. In the preferred embodiment of the invention, the central computer 12 includes interface software and hardware to communicate with the various interfaces required by the available payment networks and to complete transactions over each interface. 
     The central computer 12 also includes a user interface to facilitate user access to the plurality of payment networks. In the preferred embodiment, the central computer 12 includes a modem 26, which allows communication over the telephone lines 24 to one or more remote computers 28, which employs the DynaComm for Windows communications program, version 3.00.40, manufactured by Future Soft Engineering, Inc. of Houston, Tex. Although in the preferred embodiment the central computer 12 communicates with a plurality of remote computers 28, as those skilled in the art will appreciate the computers 28 need not be remote and can comprise any number of computers from a single computer to the maximum number capable of support by the central computer 12. Moreover, although a modem 26 and telephone lines 24 are the preferred method of communication to the remote computers 28, as those skilled in the art will also appreciate any number of communication interfaces will suffice for communication to the remote computers 28. For example, the telephone lines 24 can be replaced by a local area network or other known means of data communication. 
     In the preferred embodiment, the central computer 12 comprises a Tandem VLX Hardware Model Number C30 mainframe computer manufactured by Tandem Computers, Cupertino, Calif. The VLX Model C30 is capable of supporting the transaction throughput required over the system 10. The remote computers 28 are preferably personal computers such as the IBM PC manufactured by International Business Machines Corp. (or equivalent clone thereof). It is also preferred that the IBM PC include an 80386 microprocessor chip, four megabytes of RAM, a 20-megabyte local hard disk drive, a 1200 bits/second modem, a VGA color monitor and a compatible mouse 14. As those skilled in the art will appreciate, however, other similar computers can be employed without departing from the spirit and scope of the invention. 
     As will be described in more detail below, the system 10 includes software to implement the user interface between the remote computers 28 and the plurality of payment networks. The software provided in the system 10 is distributed between the remote computers 28 and the central computer 12. The software executing on the central computer 12 provides the functions necessary for completing the requested payments received from the remote computers 28 over the various payment networks. The software executing at the remote computers 28 provides the unique user interface of the invention to allow users access to the plurality of payment networks. This unique user interface allows access to any number of dissimilar payment networks through a single video display screen appearing at the remote computers 28 and using a single data input protocol. 
     Turning now to the user interface of the invention, an example of one preferred desk top screen displayed at the remote computer 28 is illustrated in FIG. 2. In the preferred embodiment of the invention, the software interface provided at the remote computers 28 is accomplished using the Microsoft Windows version 3.1 operating system manufactured by the Microsoft Corporation. As those skilled in the art will appreciate, therefore, various facilities are provided within the Windows 3.1 operating system that allow for file access and program initiation. As shown in FIG. 2, the interface program executing at the remote computers 28 provides facilities for all the various functions necessary to initiate a payment transfer, as well as other system maintenance or communications functions, required by the system 10. These functions include funds transfer, communications, information reporting, security, services/utilities and file management, and are subdivided into various windows 32-42 appearing on the desk top screen 30. The communications 34, information reporting 36, security 38, services/utilities 40 and file handling 42 aspects of the software interface are handled in conventional manners and need not be discussed further herein. The funds transfer screen 32, however, includes the sub-routines of the user interface that provide access to the plurality of payment networks and is described in more detail below. 
     In the funds transfer window 32 a plurality of icons including a transaction entry icon 44 are displayed to the user. In the preferred embodiment of the invention, the mouse 14 can be used to manipulate a cursor across the display screen displaying the desk top screen of FIG. 2. Using the mouse 14, or the keyboard 15, the user selects the transaction entry icon 44 appearing in the funds transfer window 32 of FIG. 2. Selecting the transaction entry icon 44 accesses the appropriate sub-routine of the software interface to initiate a payment transfer over one of the payment networks. Selecting the transaction entry icon 44 also brings up a separate transaction entry screen. An example of the preferred transaction entry screen, appearing on the remote computer 28 upon selection of the transaction entry icon 44, is shown in FIG. 3. 
     Once a payment transaction has been input by the user using the transaction entry screen of FIG. 3, approval of the transaction takes place. The approval process also occurs at the remote computers 28 and employs the transaction approval sub-routine of the software interface. Thus, in a similar manner the transaction approval routine is initiated by selecting the transaction approval icon 46 shown in FIG. 2. The approval of a transaction initiated by the user is discussed in more detail below in connection with FIG. 10. 
     The transaction entry screen 48 shown in FIG. 3 allows both free-form and repetitive entry techniques as methods of initiating a payment transfer. In the free-form entry of data, the user inputs data through a keyboard 15 coupled to the display 17 of the remote computer 28. In the repetitive entry of transaction data, previous transactions over the system 10 can be stored under a specific setup name for future use. To initiate a repetitive transaction, therefore, the setup name previously entered by the user is typed in the &#34;Setup Name&#34; field 60 shown in FIG. 3. In the repetitive transaction initiation format, the remaining fields appearing in FIGS. 3 and 4 will be filled in using stored data provided from the stored setup, including a selection of the appropriate payment network. In the free-form manner of transaction initiation, the fields appearing in FIGS. 3 and 4 must be individually completed and filled in by the user. 
     In the free-form manner of transaction initiation, the fields necessary to be completed by the user include an account field 62, a transaction type field 64, and an amount field 66. The account field 62 represents the user&#39;s account at the bank housing the central computer 12 or a related bank. The transaction type field 64 that allows the user to specify the particular payment network desired for completion of the particular transaction. The amount field 66 provided in a transaction entry screen 48 can include a default amount or simply be blank in amount awaiting input of the transaction amount. 
     Based on the specific transaction type selected by the user or identified in the transaction type field 64, the various other fields appearing throughout the transaction entry screen, as well as other successive screens (see FIGS. 5-9), are dynamically enabled or disabled as determined by the software interface for the particular payment network chosen. In the transaction entry screen 48, these fields include a beneficiary field 70, an account number field 72, an account-with bank field 74, an intermediary field 76 and a text field 80. One or more of these fields may be appropriate to the particular payment network chosen by the user for completion of a particular transaction. For ACH payment network transactions, an ACH code field 68 is also provided, as will be described in more detail below. 
     As those skilled in the art will appreciate, several other features and functions are provided on the transaction entry screen of FIG. 3, which form a part of the software interface. These features and functions are facilitated by the Windows 3.1 operating system and include drop-down lists 80, field pick-data buttons 82 and system function buttons 84. These features are well-known in the art and need not be described in detail herein. 
     After the user fills in the account field 62 and the transaction type field 64, certain of the remaining fields appearing in the transaction entry screen 48 will change dynamically. For example, certain fields may change in terminology or length of valid input allowed, or may become &#34;grayed out&#34; to indicate their inapplicability to the specific transfer type selected. (In the display shown in FIG. 3, most of the fields appear grayed out as the interface awaits input of either a setup name or account number, at which time the appropriate fields of the transaction entry screen 48 are converted to normal video.) Examples of those fields that may change in valid input length include the text field 78, the beneficiary field 70 and the account-with bank field 74. Those fields that may be grayed out based on the transaction type selected by the user include the intermediary field 76; the ID code field 6; the ACH code field 68; the routing code fields 88; the account-with bank field 74; and the city field 90, state field 92 and county fields 94. 
     As can be seen, the various fields appearing on the transaction entry screen 48 may require differing formats depending on the transaction type selected. For example, the text field 78 is different for every type of transaction. Some transaction types such as the Federal Reserve Bank Fedwire network allow a free-format text area for the text field 78. Other transaction types such as the ACH network require a set format for the text field 78. 
     In the repetitive mode of transaction initiation, the user may select from a variety of stored payment transfers identified by various setup names. Accordingly, the setup name field 60 has associated therewith a pick-data button 82. As each payment transfer is entered by the user through the transaction entry window 48, the user can choose to store the specifics of that transfer as identified by a particular setup name. Selecting the setup name pick-data button 82 causes a listing of the various setup names stored on the system to appear in an enlarged setup name field 60 appearing on the transaction entry screen 48. The user can thus highlight any of the stored setup names and input that setup in the setup name field 60. Based upon the setup chosen, the proper information for the remaining fields in the transaction entry window 48 will propagate from the interface to the display. The amount field may include a default amount, which can be changed by the user. The transaction type field 64 and text field 78 may also be changed by the user if the particular setup so allows. 
     As shown in FIG. 3, many of the remaining fields of the transaction entry screen 48 include such pick-data windows 82. In particular, the transaction type field 64 includes a pick-data button 82, which preferably displays on the transaction entry screen 48 an enlarged window identifying all of the payment networks to which a particular user has access. The account field 62 also includes a pick-data button 82, which operates in a similar manner. 
     Upon completion of the pertinent data required for a particular payment transfer, the user will select the &#34;Accept&#34; system function button 84. When the Accept system function button 84 has been &#34;depressed&#34; the interface will either validate the input and display error messages if appropriate, for example, for additional transaction details required for the transaction type selected (see FIG. 4), or will accept the transaction and place a status indication in a summary field 81 for the particular transaction. In the preferred embodiment of the invention, after each transaction has been accepted it is stored on a data base (not shown) provided at the remote computer 28. Upon a regular interval, i.e. hourly, daily or weekly, the transactions stored on the various remote computers 28 are processed for approval. The transaction approval process is discussed in more detail below in connection with FIG. 10. 
     Based on the particular transaction type selected, further information may be allowed by the software interface. Referring to FIG. 4, for example, if the wire payment network was selected as the transaction type additional transaction details are allowed. Thus, FIG. 4 illustrates a preferred additional transaction details screen 90. As shown in FIG. 4, in addition to the fields already discussed in connection with the transaction entry screen 48, a settlement type window 92 and terms window 94 are provided. In the software interface, data entered on the transaction entry screen 48 will propagate to the additional transaction details screen 90 to complete those fields common to both screens. However, to provide further instructions for each transaction over the Fedwire or CHIPS payment networks the user can select from four terms appearing in the terms window 94. Examples of the terms that can be selected include a priority transfer, to deduct charges from the beneficiary, conditional payment or to deduct correspondent charges. Once the additional data provided in the additional transaction details screen 90 is complete, the user selects the &#34;O.K.&#34; system function button 84. 
     Referring to FIGS. 5-9, if the ACH payment network is specified in the transaction type field 64 (FIG. 3) further additional information may be required. FIGS. 5-9 thus illustrate additional information screens required for the various types of ACH transfers. FIG. 5 prompts the user for additional information for a CCD+ type ACH transfer; FIG. 6 prompts the user for additional information required for a PPD+ACH type transfer; FIG. 7 prompts the user for additional information for a TXP ACH type transfer; FIG. 8 prompts the user for additional information required by a CTP ACH type transfer; and FIG. 9 prompts the user for additional information required by a CTX ACH type transfer. As mentioned above, once all the pertinent data is specified and entered for each particular payment transfer, the transaction is stored at the remote computer to await transaction approval. 
     Referring to FIG. 10, a preferred transaction approval screen 100 is shown. As displayed in FIG. 10, the plurality of transactions awaiting approval are listed for a system operator who has been given access to the transaction approval screen 100. The transaction approval screen 100 includes several categories with which to identify each transaction awaiting approval. These categories include a PC reference category 102, a currency category 104, an amount category 106, a setup name category 108 (where appropriate), a beneficiary/receiver category 110, and a status category 112. 
     FIG. 11 illustrates the transaction entry function flow as seen from the back office terminals 120 provided at the central bank. As indicated at the top of FIG. 11, a payment may be initiated in either of two fashions on the system 10. The payment may be entered by the user by hand as illustrated by the payment entry box 130, or the payment may be imported from other files as shown by the import entry box 132. As described above, payments first entered by the user may be saved as a setup 134. Setups may also be entered in advance of any transfer (box 136), and all setups are approved as shown at step 138. A setup repair step 140 is also provided in FIG. 11. 
     Once a payment is entered, the payment may be first approved or verified at the remote locations before it is communicated to the central bank (see FIG. 10). As shown in FIG. 11, a payment is approved at step 142, and rejected payments can be repaired by the user at step 144. After a transaction entry has been approved it may be further reviewed at step 148, but is ultimately transmitted to the central bank at step 150. Those transactions rejected by the central bank are sent back through path 152 to the remote location for payment repair (step 144). Valid, approved payment transactions transmitted to the bank are then forwarded to a back office terminal 120 in order to complete the transaction. As shown by step 156, status reports are also available at the central bank showing transmission errors or acknowledgements and control data. 
     Referring now to FIG. 12, a detailed flow chart of the software interface is provided. A copy of the actual code used to implement the software interface of the invention appears in the Appendix. In the preferred embodiment of the invention, the software was written primarily in a proprietary object-oriented programming language called &#34;Actor&#34; developed by the Whitewater Group, Evanston, Ill. As those skilled in the art will appreciate, however, other programming languages and techniques can be employed to achieve the software interface without departing from the spirit and scope of the invention. For example, the C programming language, or any of its enhancements (C++ and turbo C++), or any combination of programming packages can be used to develop the software interface. 
     Referring to FIG. 12A, a detailed flow chart for implementation of the transaction entry screen 48 (FIG. 3) is illustrated. The transaction entry screen 48 is first initialized at step 160 and a check is made at step 162 to determine if any work is currently in progress. If not, the interface then waits for either input of a setup name or an account number at step 164. If a setup name is provided, the program branches at step 166 to retrieve the setup and fills in all appropriate fields at step 168. Those fields not necessary for the specific setup are disabled at step 174. If an account number is provided, the program branches at step 170 to display all available and valid transaction types at step 172 subscribed to by the user. 
     At step 176, the user selects and provides the preferred transaction type for the particular payment transfer. Based on the transaction type selected, therefore, certain additional functions are performed, as described above. For example, where an ACH transfer has been selected, the program proceeds to display the available ACH codes at step 178 and enables the &#34;More&#34; system function button 84 (FIG. 3) at step 180. On the other hand, where a SWIFT, foreign currency wire or book transfer is selected by the user, the available currencies are retrieved at step 182 and the conversion rate for each currency is calculated at step 184. After completing either the ACH or SWIFT/foreign currency wire/book transfer branches of the program, or if a Federal Reserve Fedwire transfer or draft transfer were selected by the user, the program proceeds to retrieve the proper cutoff times for the transaction at step 186. 
     In the cutoff time function, the program determines the appropriate time frame in which to complete the requested payment transfer. The best value date is calculated at step 188 and the cutoff date and time are calculated and displayed at step 190. A more detailed flow chart of the cutoff time calculation appears in FIG. 12D, and is described in more detail below. 
     After the cutoff date and time are calculated and displayed, the program determines the ranges and maximum lengths for all fields appearing on the transaction entry screen 48 (FIG. 3) at step 192. The interface then allows the user to input data to the appropriate fields at step 194, and then waits for one of the system function buttons 84 to be &#34;depressed&#34; at step 196. Upon activation of the &#34;Clear&#34; function button 84 (FIG. 3) the flow returns to step 164 to await entry of a new transaction. Should the &#34;More&#34; system function button 84 have been depressed, the program proceeds to display the additional screens of FIGS. 4-9 at step 198. Should the user select the &#34;Accept&#34; system function button 84, the program proceeds to perform validity checks at step 200. A detailed illustration of the validity check routine appears in FIGS. 12B and 12C. 
     Referring to FIGS. 12B and 12C, the flow of the validity analysis sub-routine is illustrated. The validity analysis sub-routine is also part of the software interface executing at the remote computers 28. Upon initiation of the validity routine at step 202, therefore, the routine checks to ensure the operator has rights to access the particular transfer and account to be verified. If so, the routine next determines at step 204 if the particular account supports the transaction type chosen. If not, an error is identified at step 206. Whenever the pre-note transaction type is chosen the routine sets the pre-note amount to zero at step 208. 
     The validity routine next checks whether the user conversion rate is on file at step 210. If so, the routine determines whether the transaction is repetitive at step 212. If the transaction is repetitive, the validity routine checks at step 214 the amount entered against the maximum amount defined by the setup. For non-repetitive transfers the routine checks the amount entered against a non-repetitive maximum amount at step 216. After either maximum amount has been checked, or if the user conversion rate is not on file, the program proceeds to step 218. 
     At step 218, the validity routine checks for any operator limits. If operator limits exist, the routine checks the data entered against those limits at step 220. After such checks, or if no operator limits exist, the program proceeds to step 222 to check for other party account numbers. If an other party account number exists the validity routine determines whether the transfer is a book transfer at step 224, and if so, performs a &#34;mod&#34; check at step 226. Upon completion of the mod check, or if no other party account number exists, the program proceeds to step 228 where it retrieves required fields, ranges and party rules. 
     Continuing in FIG. 12C, the validity routine next determines whether data input by the user is valid or present at steps 230-238. At step 240, the routine determines whether the transaction entry was imported. If so, the routine determines the maximum length of the imported transfer at step 242 and proceeds to step 244. For non-imported transfers the program proceeds directly to step 244 where a determination of whether the ACH network is specified is made. If the transfer is not an ACH transfer then the program checks for illegal characters at step 246 and proceeds to step 248 to check ranges. Ranges are also checked at step 248 if the transfer is an ACH type payment. Finally, the validity routine determines if any errors or warnings were generated at step 250. The value returned to the main interface routine is zero if any errors or warnings occurred (step 254). If the transaction is valid, a true value is returned to the main program at step 252. 
     Referring now to FIG. 12D, a detailed flow chart of the cutoff time calculation is illustrated. At step 260, the cutoff time sub-routine sets the cutoff date equal to the effective date. At step 262 the cutoff sub-routine retrieves the particular cutoff default for the type of transaction selected. A determination is made at step 264 if the default cutoff time for the transaction is to be employed. If not, a customer adjustment to the default cutoff time is added at step 266 and the program returns to step 268. If the default cutoff time will be employed, the sub-routine determines at step 268 if a negative cutoff time is selected. A negative cutoff can be supplied by the user as another form of transaction protection. If so, the cutoff time sub-routine calculates the number of days to back up at steps 270 and 272. The sub-routine also determines if the backup date is a business day at step 274. If not, the sub-routine backs up another day at step 272. 
     The cutoff time sub-routine proceeds at step 276 to convert the cutoff time into a time of day. Thus, the cutoff time and date are set at step 278 and again a determination is made if the cutoff date falls on a business day at step 280. If not, the sub-routine backs the cutoff date one day at step 282. Next, the sub-routine checks for matching time zones for the location of transaction initiation and transaction completion at step 282. If these time zones differ, the sub-routine converts the cutoff time and date into local time at step 284. The sub-routine is exited at step 286 where a valid cutoff time and date have been set. 
     A hierarchical depiction of the data base design for transaction entry and processing over the system 10 employing the preferred object-oriented programming language is shown in FIG. 13. At the top of FIG. 13 is a business object box 290. In the context of the invention, the business object box 290 represents the unified payment transfer system of the invention. In this system, a payment initiation is seen as an instruction 292 in the hierarchy of FIG. 13. Upon selection of a funds transfer at point 294, the software interface branches to the rules associated with various payment networks coupled to the system 10. As illustrated in FIG. 13, these payment networks can include an ACH payment network 296, a branch payment network 297, a &#34;will receive&#34; transfer 298 and a Fedwire transfer 300. At points 292 and 294, therefore, all data received by the interface is common to all of the various payment networks and options available to each user. Upon designation of either the branch payment network 297, &#34;will receive&#34; transfer 298 or Fedwire transfer 300, the interface receives the rules associated with the respective payment network. 
     For ACH transfers 296, however, further identification of the specific ACH type of transfer is required. Accordingly, for CCD transfers 302, CTP transfers 304, CTX transfers 306, PPD transfers 308, and TXP transfers 310 further processing may be necessary. As a result, in response to selection of the &#34;More&#34; system function button 84 (FIG. 3) the addenda rules identified at points 312-324 for the various ACH type transfers are supplied by the data base to the interface software. 
     As can be seen, the system described above provides bank customers the unique ability to access any of a number of payment networks through a single user interface. The customer can thus initiate a plurality of payment transactions through the single user interface without employing redundant computer hardware or differing system protocols. These advantages are further enhanced because the interface to the plurality of payment networks is provided through a single computer screen. 
     Accordingly, the single user interface of the invention provides a uniform gateway to the plurality of national and international payment networks. This single user interface provides advantages to both the bank and its customers. With a single user interface and system, a bank no longer needs to support and maintain differing hardware and software systems products provided to its customer base. The primary advantage to the customer is the ease of initiation of any form of payment transfer over a single system employing a single communications protocol. A further advantage to the customer is the elimination of redundant computer equipment which can result in increased costs and fees, and take up valuable office space. 
     It is to be understood that a wide range of changes and modifications to the embodiments described above will be apparent to those skilled in the art and are contemplated.
