Abstract

A system and method for correcting data in data fields of financial documents containing unreadable characters is described.

Claims

1. A computer-implemented system for correcting MICR data fields on financial documents, comprising:

a controller configured to receive MICR data from a document processor that is operable to retrieve MICR data from a plurality of financial documents;

wherein the controller is programmed to perform data correction functions on the MICR data, the data correction functions further comprising comparing an erroneous number in said MICR data with a plurality of correct numbers and electronically replacing the erroneous number with a number from said plurality of possible numbers.

2. The system of claim 1, wherein the MICR data includes a bank routing number, and further wherein the erroneous number is a bank routing number, and further wherein the plurality of possible numbers include a list of valid bank routing numbers.

3. The system of claim 1, wherein the erroneous number has a first plurality of known correct characters and at least one known incorrect character.

4. The system of claim 3, wherein the controller is configured to determine all correct numbers from the plurality of numbers that have the first plurality of correct characters.

5. The system of claim 4, wherein the controller is configured to replace all incorrect characters of the erroneous number with corresponding characters of the only one number when there is only one number of the determined correct number that was determined to be correct.

6. The system of claim 4, in which the controller is configured to replace a first character of said at least one known incorrect character in a first character position with a replacement character if all of the correct numbers have said replacement character in respective first character positions of all of said correct numbers.

7. The system of claim 5, wherein the controller is configured to correct the erroneous number by replacing all incorrect characters in a RAM buffer of the controller.

8. The system of claim 1, wherein the controller is operable to correct erroneous numbers from at least two MICR data fields on each of the plurality of financial documents by comparing an erroneous number in said MICR data in each of the at least two MICR data fields with a plurality of possible numbers for each of the at least two MICR data fields and by electronically replacing the erroneous number with a number from said plurality of possible numbers.

9. The system of claim 1, further comprising the document processor.

10. A computer-implemented method for correcting MICR data on financial documents, comprising the steps of:

electronically comparing an erroneous number in said MICR data with a plurality of possible numbers and electronically replacing the erroneous number with a number electronically selected from said plurality of possible numbers.

11. The method of claim 10, wherein the step of electronically comparing includes the step of electronically comparing an erroneous bank routing number in said MICR data with a list of valid bank routing numbers and electronically replacing the erroneous bank routing number with a bank routing number from said list of valid bank routing numbers.

12. The method of claim 10, wherein the erroneous number comprises a first plurality of known correct characters and at least one unrecognized character.

13. The method of claim 12, further comprising the step of determining all correct numbers from the plurality of possible numbers that have the first plurality of known correct characters.

14. The method of claim 13, further comprising the step of replacing all incorrect characters of the erroneous number with corresponding characters of the only one number when there is only one number of the determined correct number that was determined to be correct.

15. The method of claim 13, further comprising the step of replacing a first character of said at least one known incorrect character in a first character position with a replacement character if all of the correct numbers have said replacement character in respective first character positions of all of said correct numbers.

16. The method of claim 14, further comprising the step of replacing the erroneous number with the only one number that was determined to be correct in a RAM buffer of the controller.

17. The method of claim 10, wherein the step of electronically comparing comprises the steps of:

electronically comparing a first erroneous number in a first MICR data field with a first plurality of all possible numbers that the first erroneous number can be and still be valid; and

electronically replacing the first erroneous number with a number selected from the first plurality based at least upon the outcome of the step of electronically comparing.

18. A computer-implemented method for correcting a line of MICR data of a financial document having an unreadable character, comprising the steps of:

electronically scanning the line of MICR data using a MICR reader;

converting the line of MICR data into a first series of numbers and storing the first series in an input buffer;

identifying a first MICR field from the first series of numbers;

sequentially comparing a readable portion of the first MICR field with each successive member of a list of valid first field numbers to determine whether a unique member of the list of valid first field numbers matches the readable portion; and

replacing the first MICR field with the unique member or with portions of the unique member that correspond to an unreadable portion of the first field.

19. The method of claim 18, wherein the step of replacing the first MICR field includes the step of replacing the first MICR field in the input buffer with the unique member or with portions of the unique member that correspond to an unreadable portion of the first field.

20. The method of claim 18, further comprising the step of leaving at least one unreadable portion of the line of MICR data unchanged.
