Claim One:
1. A computer-implemented method to extract financial card information, comprising: associating, by the one or more computing devices, expected aspect ratios for each of a plurality of card types in a database, the card types having different expected aspect ratios; receiving, by one or more computing devices, an image of a card, the card being of a particular card type; identifying, by the one or more computing devices, lines of the image in one or more edge finder zones; identifying, by the one or more computing devices, a plurality of quadrilaterals formed by intersections of extrapolations of the identified lines; adjusting, by the one or more computing devices, a perspective of the one or more quadrilaterals until the one or more quadrilaterals are fronto-parallel; determining, by the one or more computing devices, an aspect ratio of each of the plurality of quadrilaterals; identifying, by the one or more computing devices, the particular card type in the database and an expected aspect ratio that is associated with the particular card type in the database; comparing, by the one or more computing devices, the determined aspect ratio for each of the plurality of quadrilaterals to the expected aspect ratio for the particular card type to identify a particular quadrilateral that matches the expected aspect ratio as a preferred card boundary; cropping, by the one or more computing devices, the image to only a portion of the particular quadrilateral that comprises account information; and performing, by the one or more computing devices, an optical character recognition algorithm on the cropped portion of the particular quadrilateral that comprises the account information.
