## Title
Method and system for conducting international electronic financial transactions

## Abstract

Converting electronic files comprising financial transaction data for supporting international electronic financial transactions. A gateway financial institution that processes electronic payments can organize files comprising international financial transactions according to the destination country. The gateway financial institution can transmit the organized transaction files to an interface that is coupled to the computing systems of foreign financial institutions. The interface can convert the transaction files from the format of the originating financial institution to the format of the receiving financial institution. The converted transaction files can then be forwarded to the respective foreign financial institutions. The interface can also transmit additional data associated with the transaction files to support settlement of the transactions.

No. 60/484,958. Applicants hereby incorporate by reference the full disclosure of U.S. application Ser. No. 60/484,958.


FIELD OF THE INVENTION
The present invention relates to international electronic financial transactions and more specifically to a method and system for accomplishing electronic financial transactions between financial systems that use different electronic file formats.
BACKGROUND OF THE INVENTION
Generally there are three different methods for completing international transactions between financial institutions. The first method relies on pre-existing relationships between banks in different countries. Typically, large banks have relationships with correspondent banks in other countries. These large banks have established their own private processes for completing international transactions. The transactions completed using these correspondent bank relationships are typically for a large amount and involve a relatively small volume of transactions. This method for completing international transactions can be expensive and is not generally available for high-volume, low-value transactions.
The second method for completing international transactions is with a check. Checks are relatively simple to use and can be written by anyone with a checking account at a financial institution. The disadvantage of checks is that they require manual processing that delays the time in which a transaction is completed and adds costs to the transaction. Currency conversions also add to the costs associated with checks.
The third method is generally referred to as a “wire transfer” from an account at one bank to an account at another foreign bank. Wire transfers are a form of electronic finds transfers (“EFTs”) and are generally more accessible in that they are not limited to large banks that have relationships with correspondent foreign banks. However, wire transfers are generally costly, particularly where several intermediaries are involved in the transaction. Because a wire transfer is costly, it is not a cost-effective method for completing low-value, high-volume transactions.
Another form of EFT that is currently used domestically is known as direct payment or direct deposit instruments (hereinafter generally referred to as “direct payment”). A direct payment instrument is an electronically transmitted instruction to credit or debit a particular account. For example, a company can use direct payment to credit the accounts of its employees, customers, vendors, and beneficiaries. Direct payment instruments are becoming increasingly more popular as conventional payment methods, such as checks, decrease in popularity. Because the transaction is performed electronically, direct payment instruments offer convenience and reliability at a relatively low cost. The electronic system that supports direct payment instruments in the United States is referred to as the Automated Clearinghouse (“ACH”).
The ACH is a nationwide system supported by several operators, including the Federal Reserve Banks and other institutions. The ACH network is governed by a set of rules, which are administered by the National Automated Clearinghouse Association (“NACHA”). The ACH network provides for the clearing of generally small value, repetitive and one-time payments among banks that participate in the ACH network. Financial institutions collect transactions and package them in batched ACH files according to the NACHA rules for forwarding to other institutions via the ACH network.
Computer networks exist in other countries and regions of the world for processing different types of transactions among foreign banks. For example, many European countries have their own domestic EFT systems for low-value transactions. Another communication network that supports the processing of certain types of payments among financial institutions in different European countries is called the Eurogiro network. The types of payment services available with the Eurogiro network include standard account payments, check payments, and urgent cash payments such as wire transfers.
Currently, the Eurogiro network is also connected to financial networks in Asia, Africa, and the U.S. However, these transactions are completed via inefficient inter-continental connections such as correspondent banking payments or wire transfers. One of the primary inefficiencies in international EFTs concerns the formats of the electronic files used to process the transactions. For example, the Eurogiro network generally uses an electronic file format called SWIFT. However, financial networks and payment systems in other countries and regions use other types of electronic file formats to process transactions. These different formats complicate the processing of international transactions. Originating and completing international transactions often requires manual steps performed by bank employees which slows down the processing and adds costs to the transaction. Slower processing also adds uncertainty as to when transactions are settled.
In view of the increasing number of international EFTs, there is a need for an efficient method for processing large volumes of low-value transactions by systems using different electronic file formats. Specifically, what is needed is a method for automatically converting between ACH file formats and the file formats of foreign financial networks. The conversion process should preserve the necessary data contained in the electronic file so that each financial network can complete the foreign transaction. The conversion process should also provide uniformity and certainty to international EFTs. There is a further need for a conversion process that can also communicate messages and other data associated with a transaction. Finally, a conversion process is needed that can automatically complete the settlement of the transaction.
SUMMARY OF THE INVENTION
The conversion processes and systems described herein provide solutions to the foregoing problems. Specifically, the conversion processes disclosed in the text and accompanying drawings support the conversion of electronic transaction files from one file format to another file format facilitating seamless processing of international electronic financial transactions. A gateway operator or institution in one country or region can transmit an electronic file containing transaction data to a converter software module. The converter software module converts the format of the file from the format used in the first country or region to a second format used in the country or region to which the file is being transmitted. The converter software module can also convert and transmit other files comprising data associated with the electronic transaction. The associated data can be used to manage records of electronic financial transactions and to settle the transactions.
In one aspect, the converter software module can receive a NACHA formatted transaction file comprising transaction data from a gateway operator in a first country. The converter software module can convert the NACHA formatted transaction file to a SWIFT formatted transaction file and transmit the SWIFT formatted transaction file to a gateway operator in a second country. The converter software module can also receive a NACHA formatted advice file comprising settlement data from a gateway operator in the first country. The converter software module can convert the NACHA formatted advice file to a SWIFT formatted advice file and transmit the SWIFT formatted advice file to a gateway operator in the second country. A receiving institution can use the SWIFT formatted transaction file and the SWIFT formatted advice file to reconcile settlement of the transaction identified by the data in the files.
In another aspect, the converter software module can receive a SWIFT formatted transaction file comprising transaction data from a gateway operator in a first country. The SWIFT formatted transaction file can be transmitted to the gateway operator from an originating financial institution. The converter software module can convert the SWIFT formatted transaction file to a NACHA formatted transaction file and transmit the NACHA formatted transaction file to a gateway operator in a second country. The converter software module can also receive a NACHA formatted advice file from the gateway operator in the second country. The NACHA formatted advice file comprises settlement data associated with the transaction received from the originating financial institution.
In yet another aspect, the converter software module can operate on a computing device coupled to a U.S. gateway operator and a European gateway operator. The U.S. gateway operator and the European gateway operator are coupled to financial institutions in their respective regions. The converter software module can receive a file in either NACHA format or SWIFT format from the U.S. or European gateway operator, respectively. The converter software module can convert files either from NACHA to SWIFT format or from SWIFT to NACHA format and transmit the converted file to the destination gateway. The destination gateway can forward the converted file to a receiving financial institution in the U.S. or Europe.
The aspects of the present invention may be more clearly understood and appreciated from a review of the following detailed description of the disclosed embodiments and by reference to the drawings and claims.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The exemplary embodiments of the present invention support the completion of electronic financial transactions. Specifically, a conversion process is described that facilitates the exchange of electronic files containing financial transaction data. The conversion process allows clearinghouse systems for electronic transactions to communicate and share transaction information despite different format conventions. In the exemplary embodiments described herein, a converter software module can receive electronic files in a first format containing transaction data. The converter software module can transfer the file in the first format to a file in a second format and transmit the converted file to a financial institution. Conversely, the converter software module can also receive a file in the second file format from a financial institution and convert that file to the first format for receipt by another financial institution. The converter software module also supports the conversion and transmittal of other electronic files containing settlement data associated with a transaction file.
Although the exemplary embodiments will be generally described in the context of software modules running in a distributed computing environment, those skilled in the art will recognize that the present invention also can be implemented in conjunction with other program modules for other types of computers. In a distributed computing environment, program modules may be physically located in different local and remote memory storage devices. Execution of the program modules may occur locally in a stand-alone manner or remotely in a client/server manner. Examples of such distributed computing environments include local area networks of an office, enterprise-wide computer networks, and the global Internet.
The detailed description that follows is represented largely in terms of processes and symbolic representations of operations in a distributed computing environment by conventional computer components, which can include database servers, application servers, mail servers, routers, security devices, firewalls, clients, workstations, memory storage devices, display devices and input devices. Each of these conventional distributed computing components is accessible via a communications network, such as a wide area network or local area network.
The present invention also includes a computer program that embodies the functions described herein and illustrated in the appended flow charts. However, it should be apparent that there could be many different ways of implementing the invention in computer programming, and the invention should not be construed as limited to any one set of computer program instructions. Further, a skilled programmer would be able to write such a computer program to implement the disclosed invention based on the flow charts and associated description in the application text, for example. Therefore, disclosure of a particular set of program code instructions is not considered necessary for an adequate understanding of how to make and use the invention. The inventive functionality of the claimed computer program will be explained in more detail in the following description in conjunction with the remaining figures illustrating the program flow.
Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of the present invention and the preferred operating environment will be described.
FIG. 1 illustrates an exemplary architecture 100 for completing an international financial transaction in the representative context of the United States and Europe. The architecture 100 represents various financial institutions involved in the completion of an international financial transaction and the computer systems they use to complete that transaction. Throughout the specification, the terms “bank” and “financial institution” are used interchangeably to refer to any institution that processes, creates, transmits, or receives data associated with a financial transaction. Similarly, the term “gateway operator” refers to any institution that processes, creates, transmits, or receives data associated with a financial transaction. A gateway operator can also be a bank or other financial institution. Although the example of a forward payment transaction is discussed in greater detail within the specification, the term “financial transaction” includes, and is not limited to, a credit, a debit, or a rejected or returned transaction. Furthermore, a “financial transaction” can also include information associated with a transaction.
The originating depository financial institution (“ODFI”) 105 receives transactions from its customers or other financial institutions and packages these transactions in electronic packets or files in a first format, such as the NACHA format. Under the NACHA format, files typically comprise batches of transactions that are generally referred to as items. Throughout this specification the term “file” includes NACHA and SWIFT formatted files as well as other more general electronic files and records that comprise data associated with a financial transaction. The NACHA format is a file format convention adopted by the Federal Reserve Banks and other financial institutions that participate in the ACH system in the U.S. The ODFI 105 submits the NACHA formatted files to the ACH system. The Federal Reserve Banks and the private financial institutions use the ACH system for clearing and settling electronic financial transactions.
The ACH system is represented in FIG. 1 as the U.S. Gateway Operator (USGO) 110. The USGO is merely one of many financial institutions within the ACH. In the example of an international transaction, as illustrated by the architecture 100 in FIG. 1, the USGO is the entity that forwards and receives international transaction data contained in NACHA formatted files. The USGO 110 transmits the NACHA formatted files to the EuroGiro Network 115. The EuroGiro Network 115 comprises computer systems coupled to various European financial institutions. The EuroGiro Network 115 comprises a EuroGiro-Fed Interface (“EFI”), also referred to as a converter software module 117, and an EFI database 118. The converter software module 117 converts the NACHA formatted transaction files to a second format, such as the SWIFT format used by European financial institutions. The converter software module 117 also stores a copy of the NACHA formatted files in the EFI database for later use. The converter software module 117 and the EFI database 118 are not required to be part of the Eurogiro Network 115. Alternative embodiments of the present invention can comprise a converter software module located in another country outside of the Eurogiro Network 115.
Once the transaction file is converted to the SWIFT format it is forwarded to the European Gateway Operator (“EGO”) 120. The EGO 120 edits the SWIFT formatted transaction file, converts the amount of the transaction to a local currency, and converts the SWIFT formatted file to a local format. The EGO 120 then forwards the locally formatted transaction file to a receiving depository financial institution (“RDFI”) 125. Unless the transaction file is rejected or returned, the RDFI 125 will credit or debit the account of its customer that participated in the original transaction forwarded from the ODFI 105.
The converter software module 117 also supports the conversion and transmittal of transaction files from Europe to the U.S. In such a transaction, the transaction file originates with an ODFI 130 in Europe in the SWIFT format. Alternatively, the ODFI 130 may create the transaction file in a local format that the EGO 120 can convert to SWIFT. The converter software module 117 converts the transaction file from SWIFT format to NACHA format. The NACHA formatted file can then be transmitted to an RDFI 135 in the U.S. via the USGO 110.
It should be understood by those skilled in the art that the architecture 100 is merely a representative example and that other computing systems and financial institutions can participate in the international financial transaction. Furthermore, the converter software module 117 can be associated with computer systems other than the Eurogiro Network 115. The process used for transactions originating from both the U.S. and Europe will be described in greater detail in the following flow diagrams.
FIG. 2 illustrates two exemplary file structures for the two file formats discussed previously. The ACH system in the U.S. employs the NACHA format illustrated in exemplary file structure 210. Many foreign financial institutions, such as those in Europe, use the SWIFT format represented by exemplary file structure 205. The file formats 205 and 210 are representative and minor variations of these formats may be implemented by those skilled in the art. The arrows shown in FIG. 2 illustrate how financial transaction data is organized during the conversion process performed by the converter software module 117.
For example, when the converter software module 117 converts a file from SWIFT format to NACHA format, it collects the data contained in the basic header, the application header, and the user header from the SWIFT formatted file and transfers this data to a single location known as the file header in the NACHA formatted file. The transaction data contained in a single field in the SWIFT formatted file is dispersed among the batch header record, the entry detail record, and the addenda record in the NACHA formatted file. Finally, the data in the trailer field in the SWIFT formatted file is transferred to the file control record in the NACHA formatted file. At a general level, the conversion process from NACHA format to SWIFT format is the reverse of the foregoing process.
As the exemplary file structure suggests, the SWIFT file format 205 was originally intended to contain data for a single transaction. In contrast, the NACHA formatted file 210 was originally intended to contain transaction records for numerous transactions that could be processed in a batch processing approach. Nonetheless neither file format is limited to its original intended purpose. The NACHA formatted file can contain only a single transaction and the SWIFT formatted file, as implemented by Eurogiro, can contain data for multiple financial transactions. Exemplary file formats are illustrated in greater detail in FIGS. 9 through 14. The file formats illustrated in FIGS. 9 through 14 are merely one means for accomplishing the conversion process and those skilled in the art will recognize that other file formats can readily be adopted to accomplish the conversion process described herein.
FIG. 3 illustrates an exemplary process 300 for performing a forward payment process for an international transaction from a U.S. financial institution to a European financial institution. The exemplary process 300 refers to steps performed by the components illustrated in exemplary architecture 100. Those skilled in the art will understand that the steps illustrated in process 300 are only one example and in alternative embodiments of the invention process 300 may be performed in a somewhat different order or may eliminate certain steps entirely.
In step 305, the ODFI 105 in the United States receives a payment instruction from a customer involving an account at a European financial institution. The ODFI 105 creates an electronic file containing the transaction data for the payment instruction in step 310. The file containing the transaction data is in the NACHA format used by the participants in the ACH system. Examples of the transaction data in the NACHA format are illustrated in FIGS. 12A through 12K. The ODFI 105 then transmits the NACHA formatted file to the USGO 110 in step 315 and, in step 320, the USGO acknowledges receipt of the file.
The USGO 110 recognizes an identifier signifying that the file is to be transmitted to the EuroGiro Network 115. In step 325, the USGO 110 edits the file and separates transactions according to destination country, settlement date, forward items and return items. In step 330, the USGO 110 transmits an edited NACHA file to the EGN 115. The EGN 115 stores a copy of the NACHA formatted file in the EFI database 118 in step 335.
Step 340 represents an exemplary process whereby the converter software module 117 converts the transaction file from a NACHA format to a SWIFT format. The sub-processes performed in connection with the conversion process are illustrated in greater detail in FIG. 4. Furthermore, FIGS. 12A through 12K illustrate file formats associated with the conversion of a forward payment from the U.S. to Europe. The file formats illustrated in FIGS. 12A through 12K show the data that the ACH system provides when sending a transaction file for the representative transaction of a forward payment to Europe. The exemplary file formats show the data values that are taken from the NACHA formatted file and inserted into the various fields of the SWIFT formatted file. If the converter software module 117 is unable to convert a transaction file, it will be rejected and transmitted back to the USGO 110 for manual handling. The term “reject” is generally used for files that cannot be processed because of erroneous data or an incorrect file format. In contrast, a “returned” file, as described in greater detail in connection with FIGS. 5 and 8, comprises a transaction that cannot be completed because, for example, an account is closed or has insufficient funds.
In step 345, the EGN 115 transmits the file that has been converted to SWIFT format to the EGO 120. If the EGO 120 is unable to process a file that has been converted to SWIFT format, the EGO will reject the transaction file. After the SWIFT formatted file is transmitted to the EGO 120, the USGO 110 settles the transaction with the ODFI 105 and the EGO 120 in step 347.
In step 350, the EGO 120 edits the SWIFT file and converts the amount of the transaction to a local currency. The EGO 120 may also convert the SWIFT file to a local file format for receipt by the RDFI 125. In step 355, the EGO 120 transmits the converted file to the RDFI 125. The transmission to the RDFI 125 can be accomplished using an electronic financial transaction system local to the RDFI 125. In step 360, the USGO 110 sends balance reports to the EGN 115 and the ODFI 105. Balance reports contain summaries of the file traffic between the different financial institutions and assists those institutions in keeping accurate records. In step 363, the USGO also sends an advice file to the EGN 115 and the ODFI 105. The advice file contains settlement information for each transaction. For example, in the context of a forward payment transaction, the advice file would reflect the settlement amount of the forward payment that was sent from the ODFI to the EGO and the settlement date.
As with the original transaction file, the converter software module 117 converts the advice file from the NACHA format to the SWIFT format in step 365. The conversion process represented in step 365 is illustrated in greater detail in FIG. 4. Exemplary format tables for the conversion of an advice file from NACHA format to SWIFT format are illustrated in FIGS. 14A through 14J. The SWIFT formatted advice file is transferred from the EGN 115 to the EGO 120 in step 368. In step 375, the EGO 120 uses the converted transaction file and converted advice file to complete the settlement of the transaction with the RDFI 125.
FIG. 4 illustrates an exemplary process for performing the conversion process using the converter software module 117. The conversion process from NACHA format to SWIFT format is illustrated in steps 340 and 365 of FIG. 3, step 550 of FIG. 5, and steps 830 and 858 of FIG. 8. The data that is transferred in the conversion process from NACHA format to SWIFT format is illustrated in greater detail in the exemplary file format tables in FIGS. 10A through 10L, 12A through 12K, and 14A through 14J.
In step 405, the converter software module 117 validates the NACHA file. If the converter software module 117 is unable to validate the NACHA file in step 407, the file will be rejected and returned to the financial institution from which it originated. Assuming the NACHA file is validated, in step 410, the converter software module 117 transfers the NACHA file header data to the SWIFT basic header, application header, and user header fields. The NACHA formatted file typically contains only one file header. The fields that comprise the NACHA file format and the SWIFT file format are illustrated in the exemplary file structures illustrated in FIG. 2.
In step 415, the converter software module 117 transfers the batch header data for one or more transactions to the transaction information field in the SWIFT formatted file. The batch header data generally contains one or more transactions for a specific customer. The entry detail record and the addenda record in the NACHA formatted file are also placed in the transaction information field in the SWIFT formatted file in steps 420 and 425. Each transaction typically has one entry detail record and one addenda record. Lastly, in step 430, the converter software module 117 transfers the control record indicating the end of the file to the trailer field in the SWIFT formatted file. It should be understood by those skilled in the art that the exemplary process illustrated in FIG. 4 may be performed in a different sequence and certain steps may be combined or eliminated.
Referring to FIG. 5, an exemplary process 500 for the return of a U.S. file from Europe is illustrated. A return typically occurs when the EGO 120 or the RDFI 125 is unable to process a transaction in the converted SWIFT file because an account lacks sufficient funds or is closed. In step 501, the RDFI 125 in Europe receives a file in a local format convention that it is unable to process. The RDFI 125 creates a return file and transmits the return file to the EGO 120 in step 502. The EGO 120 and RDFI 125 typically complete settlement of the transaction at step 503. While FIG. 5 and the other figures described herein illustrate settlement occurring at discrete points in time, those skilled in the art understand that settlement of a transaction typically involves several steps that occur over a period of time. For example, a financial institution can record a transaction at one point in time, but the transfer of finds can occur at a later point in time. The processes described herein are merely representative and the steps of each exemplary process need not necessarily occur in the described sequence.
The EGO 120 converts the locally formatted file to a SWIFT formatted file and converts the currency to U.S. dollars in step 504. In step 505, the EGO 120 transmits the SWIFT formatted return file to the EGN 115. If the EGO was unable to process the SWIFT formatted file, it typically would not have been forwarded to the RDFI 125 and the return process would begin at step 505.
In step 510, the converter software module 117 converts the return file from SWIFT format to NACHA format. The process for converting the SWIFT formatted file to the NACHA format is illustrated in greater detail in FIG. 7. In step 515, the converter software module 117 compares the converted return file to the NACHA formatted file previously stored in the EFI database 118 in step 335. The stored NACHA formatted file contains the data transmitted by the USGO 110 during the initial forward payment process 300. The comparison step is used to retrieve additional data which may have been lost during the conversion processes.
In step 520, the EGN 115 transmits the converted return file to the USGO 110 and the USGO 110 transmits an acknowledgement to the EGN 115 in step 525. The USGO 110 periodically collects returned files received from the EGN 115 and creates output return files for transmitting to various ODFIs 105 as illustrated in step 530. The output return files are typically organized according to each RDFI 125. In steps 535 and 540, the ODFI 105 that originally transmitted the transaction for the representative example of a forward payment illustrated in FIG. 3 receives the output return files from the USGO 110. In steps 545 and 547, the USGO 110 transmits the balance reports and the advice files to the EGN 115 and the ODFI 105. The financial institutions use the balance reports to manage the file traffic and to ensure their records are accurate. The advice files contain settlement data including the timing for the settlement of the transaction. In steps 550 and 555 the converter software module 117 converts the advice file to SWIFT format and the file is transmitted to the EGO 120. Lastly, in step 560, the EGO 120 settles the return transaction with the USGO 110 and the USGO 110 settles the return transaction with the ODFI 105.
FIG. 6 illustrates an exemplary process 600 for processing a forward payment from a European financial institution to a U.S. financial institution. Although the process for handling a transaction from Europe to the U.S. is similar to the process illustrated in FIG. 3, there are certain distinctions as shown in process 600. In step 605, the ODFI 130 in Europe receives a payment instruction involving a U.S. account. The ODFI 130 creates a file with transaction data in the local format in step 610 and transmits the transaction file in a local format to the EGO 120 in step 615. In steps 620 and 625 the EGO 120 converts the file from a local format to the SWIFT format and performs the necessary exchange on the transaction amount to U.S. dollars. In alternative embodiments of the invention the ODFI 130 in Europe can use the SWIFT format instead of a local format making the format conversion in step 620 unnecessary. The EGN 115 receives the SWIFT formatted file and stores a copy of the file in the EFI database 118 in step 630. The stored copy of the SWIFT formatted file can be used later to verify records and to process any returned transactions.
In step 635, the converter software module 117 converts the SWIFT formatted file to NACHA format. An exemplary process for performing the conversion from SWIFT to NACHA format is illustrated in greater detail in FIG. 7. Representative file formats containing the data that is transferred from the SWIFT format to the NACHA format are illustrated in FIGS. 9A through 9K. In steps 640 and 645 the USGO 110 receives the NACHA formatted file from the EGN 115 and responds with an acknowledgement. The USGO 110 collects NACHA formatted files from financial institutions within the ACH system as well as foreign financial institutions. The USGO 110 uses the adopted NACHA format to organize and route the transaction files to the appropriate financial institutions in the U.S. In step 650, the USGO 110 edits the NACHA formatted file received from EGO 120 and sends the output files to the appropriate RDFI 135.
In step 653, the USGO 110 settles the transaction contained in the output files with the RDFI 135 and the EGO 120. The USGO 110 transmits balance reports and advice files to the EGN 115 and the RDFI 135 in steps 655 and 657. In the embodiment illustrated in FIG. 6 of a forward payment from Europe to the U.S., the EGO 120 typically does not receive converted advice files from the EGN 115. Because the forward payment originated with the EGO 120, EGOs typically do not require receipt of a debit settlement item. In alternative embodiments of the invention, such as a debit item that originates in Europe, the EGO 120 may request to receive a credit settlement item. In those instances where the EGO 120 requires receipt of the settlement item, the converter software module 117 converts the advice file from NACHA to SWIFT format and the converted advice file is sent to the EGO 120. As in the previous conversion steps from NACHA format to SWIFT format, the NACHA to SWIFT conversion process is illustrated in greater detail in FIG. 4. Additionally, FIGS. 14A through 14J contain exemplary file format tables for the conversion of an advice file.
Referring to FIG. 7, an exemplary conversion process, as identified in steps 510 and 635, is illustrated. The exemplary process illustrated in FIG. 7 describes the conversion of an electronic file from SWIFT format to NACHA format. In step 705, the converter software module 117 validates the transaction file received from a gateway operating financial institution. If the converter software module 117 is unable to validate the file, it is rejected and transmitted back to the financial institution from which it was received. Assuming the validation process is completed, the converter software module 117 proceeds to transfer the data in the file from the SWIFT format to the NACHA format. Representative file formats are illustrated in greater detail in FIG. 2. Additionally, FIGS. 9A through 9K show the data that is transferred in accordance with an exemplary conversion process.
In step 710, the converter software module 117 transfers the header information in the SWIFT basic header to the NACHA file header. In steps 715 and 720, the converter software module 117 transfers the application header data and the user header data to the NACHA file header. Unlike the SWIFT file format which comprises three distinct file headers, the NACHA file format generally consists of a single file header. In step 725, the converter software module 117 transfers information for a particular transaction to the batch header field, the entry detail field and the addenda record field in the NACHA formatted file. In the NACHA format each transaction comprises an entry detail record and an addenda record. Furthermore, in the NACHA formatted file data for multiple transactions can be grouped into a batch with a header record and a control record. Lastly, in step 730, the converter software module 117 transfers the trailer information from the SWIFT formatted field to the file control record in the NACHA formatted file.
Exemplary process 800 illustrated in FIG. 8 describes the return of a financial transaction from a U.S. institution to a European financial institution. The return process 800 may occur when a transaction cannot be completed such as the forward payment transaction illustrated in process 600. For example, if a party no longer maintains an account at the RDFI, the RDFI will not be able to complete the transaction and will transmit a return item to the originating institution.
Referring now to the exemplary process 800, in step 805, the RDFI in the U.S. transmits a NACHA file with the return transaction to the USGO 110. The USGO 110 transmits an acknowledgement to the RDFI 135 and edits the file and separates return items on a country and settlement date basis in steps 810 and 815. In step 820, the USGO 110 transmits separated files to the EGN 115. A copy of received file is stored in the EFI database 118 in step 825 and the converter software module 117 proceeds to convert the file to SWIFT format in step 830. The conversion process is illustrated in greater detail in FIG. 7. Exemplary file format tables illustrating the data that is typically transferred in a conversion process for a return file from the U.S. to Europe are contained in FIGS. 10A through 10L.
The EGN 115 also refers to the file that was stored in the EFI database 118 when the forward payment file was originally converted in step 833. The stored file can be used to assemble additional data that may have been lost in the conversion process. In step 835, the EGN 115 transmits the SWIFT formatted return file to the EGO 120. The EGO 120 edits the return file and converts the transaction amounts to the local currency of the originating European financial institution in step 840. At this point, the USGO 110 can complete settlement of the transaction with the RDFI 135 and the EGO 120. The EGO 120 also transmits the return file to the ODFI 130 in Europe in step 845.
Completion of the return transaction is accomplished with the transfer of the balance and advice files. In steps 855 and 857, the USGO will transmit balance reports to the EGN 115 and the balance report and advice file to the RDFI 135 in the U.S. As illustrated in FIG. 4, the advice file is converted from NACHA format to SWIFT format and transmitted to the EGO 120 in steps 858 and 859. Lastly, in step 860 of exemplary process 800, the EGO 120 in Europe settles the transaction with the ODFI 130, generally via the process employed by the local electronic financial transaction system.
In conclusion, the present invention enables and supports communication among different financial transaction systems located in different regions of the world. The systems and processes described herein allow for the conversion of financial transaction files from a first format to a second format. For example, the first format can be used in a first geographical region and the second format can be used in a second geographical region. The conversion processes also support the transfer of data associated with the financial transactions enabling settlement of the transaction without manual steps. The conversion processes allow international financial transactions to be completed more quickly and with greater certainty as to the time period in which they will be completed.
It will be appreciated that the present invention fulfills the needs of the prior art described herein and meets the above-stated objectives. While there has been shown and described the preferred embodiment of the invention, it will be evident to those skilled in the art that various modifications and changes may be made thereto without departing from the spirit and the scope of the invention as set forth in the appended claims and equivalence thereof. It should be readily apparent that the components of the conversion module can be located in various local and remote locations of a distributed computing environment. Although the present invention has been described as operating with financial systems in the U.S. and Europe, it should be understood that the invention can be applied to other financial systems located throughout the world.
