18. A method of reading magnetic ink characters on a check, comprising:
moving the magnetic ink characters relative to a magnetic reading head in a first direction and at a first speed;
decoding a first version of the magnetic ink characters based on an output from the magnetic reading head;
storing the decoded first version of the magnetic ink characters;
moving the magnetic ink characters relative to the magnetic reading head in a second direction and at a second speed determined based on the output of the magnetic reading head in the first direction, wherein second direction is reversed from the first direction;
decoding a second version of the magnetic ink characters based on an output from the magnetic reading head;
storing the decoded second version of the magnetic ink characters;
moving the magnetic ink characters relative to a magnetic reading head in a third direction and at a third speed;
decoding a third version of the magnetic ink characters based on an output from the magnetic reading head; and
generating an output signal based upon a comparison of the three decoded versions of the magnetic ink characters.
