Abstract

Comparing extracted card data from a continuous scan comprises receiving, by one or more computing devices, a digital scan of a card; obtaining a plurality of images of the card from the digital scan of the physical card; performing an optical character recognition algorithm on each of the plurality of images; comparing results of the application of the optical character recognition algorithm for each of the plurality of images; determining if a configured threshold of the results for each of the plurality of images match each other; and verifying the results when the results for each of the plurality of images match each other. Threshold confidence level for the extracted card data can be employed to determine the accuracy of the extraction. Data is further extracted from blended images and three-dimensional models of the card. Embossed text and holograms in the images may be used to prevent fraud.

First claim

1. A computer-implemented method to compare extracted card data, comprising:
performing, by one or more computing devices, an optical character recognition algorithm on each of a plurality of images obtained from a digital scan of a card, the digital scan being a continuous digital scan;
determining, by the one or more computing devices, if a configured threshold number of results for each of the plurality of images match each other based on a comparison of the results of the performance of the optical character recognition algorithm on each of the plurality of images; and
verifying, by the one or more computing devices, the matching results as card data when at least the configured threshold number of results for each of the plurality of images match each other is reached.

2. The method of claim 1 , further comprising:
accessing, by the one or more computing devices, at least one additional digital image of the card when the one or more computing devices determines that at least the configured threshold number is not reached;
performing, by the one or more computing devices, the optical character recognition algorithm on each additional image of the card; and
including, by the one or more computing devices, the results of the performance of the optical character recognition algorithm to each additional image in the determining.

3. The method of claim 2 , wherein the at least one additional image is accessed from the plurality of images obtained from the digital scan of the card.

4. The method of claim 2 , further comprising performing a second digital scan of the card to obtain the at least one additional image.

5. The method of claim 1 , wherein the results are determined to match when a percentage of matching digits meets or exceeds the configured threshold.

6. The method of claim 1 , wherein the digital scan is received from a camera.

7. The method of claim 1 , wherein the digital scan comprises a video or a plurality of still images.

8. The method of claim 1 , wherein the card is a credit card, a debit card, an identification card, a loyalty card, an access card, or a stored value card.

9. A computer program product, comprising:
a non-transitory computer-readable storage device having computer-executable program instructions embodied thereon that when executed by a computer cause the computer to compare extracted card data from multiple images to identify matched extraction results, the computer-executable program instructions comprising:
