Abstract

Extracting card information comprises a server at an optical character recognition (“OCR”) system that interprets data from a card. The OCR system performs an optical character recognition algorithm an image of a card and performs a data recognition algorithm on a machine-readable code on the image of the card. The OCR system compares a series of extracted alphanumeric characters obtained via the optical character recognition process to data extracted from the machine-readable code via the data recognition process and matches the alphanumeric series of characters to a particular series of characters extracted from the machine-readable code. The OCR system determines if the alphanumeric series and the matching series of characters extracted from the machine-readable code comprise any discrepancies and corrects the alphanumeric series of characters based on the particular series of characters extracted from the machine-readable code upon a determination that a discrepancy exists.

First claim

What is claimed is:

1. A computer-implemented method to extract information from objects, comprising:
extracting, by one or more computing devices, a series of extracted characters on a digital representation of an object using an optical character recognition process;
performing, by the one or more computing devices, a data recognition process on a machine-readable code on the digital representation of the object;
comparing, by the one or more computing devices, the series of extracted characters obtained via the optical character recognition process to a series of extracted characters from the data extracted from the machine-readable code via the data recognition process;
determining, by the one or more computing devices, that the series of characters determined via the optical character recognition process performed on the digital representation of the object and the series of characters extracted from the data extracted from the machine-readable code comprise one or more discrepancies;
upon a determination that one or more discrepancies between the series of characters determined via the optical character recognition process and the data extracted from the machine-readable code exists, correcting, by the one or more computing devices, the series of characters determined via the optical character recognition process performed on the digital representation of the object based on the particular series of characters extracted from the machine-readable code; and
communicating, by the one or more computing devices and to a user computing device, the corrected series of characters and instructions to display the corrected series of characters via the user computing device.

2. The method of claim 1 , wherein the series of extracted alphanumeric characters and the particular series of characters extracted from the data extracted from the machine-readable code are determined to match based on an identification, by the one or more computing devices, of at least a threshold number of matching characters between the extracted alphanumeric characters and the particular series of characters extracted from the data extracted from the machine-readable code.

3. The method of claim 2 , wherein the threshold is based on a percentage of the characters matching.

4. The method of claim 1 , further comprising determining, by the one or more computing devices, a match between the series of characters determined via the optical character recognition process performed on the digital representation of the card to the particular series of characters extracted from the data extracted from the machine-readable code, wherein the series of extracted characters obtained via the optical character recognition process is compared to the series of extracted characters from the data extracted from the machine-readable code via the data recognition process in response to determining the match.

5. The method of claim 1 , wherein the machine-readable code comprises a barcode.

6. The method of claim 1 , wherein the series of extracted characters comprises an alphanumeric series of characters comprising an identification code for an account of a user.

7. The method of claim 6 , wherein the series of extracted characters comprises a redemption code of a gift card.

8. A computer program product, comprising:
a non-transitory computer-readable storage device having computer-readable program instructions embodied thereon that when executed by a computer cause the computer to extract card information, comprising:
computer-readable program instructions to extract a series of extracted characters on a digital representation of an object using an optical character recognition process;
computer-readable program instructions to perform a data recognition process on a machine-readable code on the digital representation of the object;
computer-readable program instructions to compare the series of extracted characters obtained via the optical character recognition process to a series of extracted from the data extracted from the machine-readable code via the data recognition process;
computer-readable program instructions to determine that the series of characters determined via the optical character recognition process performed on the digital representation of the object and the series of characters extracted from the data extracted from the machine-readable code comprise one or more discrepancies;
computer-readable program instructions to correct, upon a determination that one or more discrepancies between the series of characters determined via the optical character recognition process and the data extracted from the machine-readable code exists, the series of characters determined via the optical character recognition process performed on the digital representation of the object based on the particular series of characters extracted from the machine-readable code; and
computer-readable program instructions to communicate, to a user computing device, the corrected series of characters and instructions to display the corrected series of characters via the user computing device.

9. The computer program product of claim 8 , wherein the series of extracted characters and the particular series of characters extracted from the data extracted from the machine-readable code are determined to match based on computer-readable program instructions to identify at least a threshold number of matching characters between the extracted alphanumeric characters and the particular series of characters extracted from the data extracted from the machine-readable code.

10. The computer program product of claim 9 , wherein the threshold is based on a percentage of the characters matching.

11. The computer program product of claim 8 , further comprising computer-readable program instructions to determine a match between the series of characters determined via the optical character recognition process performed on the digital representation of the card to the particular series of characters extracted from the data extracted from the machine-readable code, wherein the series of extracted characters obtained via the optical character recognition process is compared to the series of extracted characters from the data extracted from the machine-readable code via the data recognition process in response to determining the match.

12. The computer program product of claim 8 , wherein the machine-readable code comprises a barcode.

13. The computer program product of claim 8 , wherein the series of characters comprises a series of alphanumeric characters comprising an identification code for an account of a user.

14. The computer program product of claim 8 , wherein the alphanumeric series of characters comprises a redemption code of a gift card.

15. A system to extract card information, comprising:
a storage device; and
a processor communicatively coupled to the storage device, wherein the processor executes application code instructions that are stored in the storage device to cause the system to:
extract a series of extracted characters on a digital representation of an object using an optical character recognition process;
perform a data recognition process on a machine-readable code on the digital representation of the object;
compare the series of extracted characters obtained via the optical character recognition process to a series of extracted from the data extracted from the machine-readable code via the data recognition process;
determine that the series of characters determined via the optical character recognition process performed on the digital representation of the object and
