1. A computer-implemented method for extracting financial card information with relaxed alignment, 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, one or more quadrilaterals formed by intersections of extrapolations of the identified lines; determining, by the one or more computing devices, an aspect ratio of each of the one or more quadrilaterals by performing a transformation function on the image to create a fronto-planar image; 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 one or more 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; and performing, by the one or more computing devices, an optical character recognition algorithm on the rectified model of the particular quadrilateral.
