Matching character strings with transaction data

Abstract:

A user may capture an image of a document using a mobile device. The mobile device may crop and clean the image. The mobile device may perform optical character recognition on the image and output a character string. The mobile device may match portions of the character string with stored records and determine a likelihood that the stored record corresponds to the image. The mobile device may display potential matches for the image, and the user may select the record which matches the image.
