1. A computer-implemented method of processing a paper substitute check which has a first magnetic ink character recognition (MICR) codeline which is printed on a first portion of the paper substitute check and a second MICR codeline which is printed on a second portion of the paper substitute check and which second portion is different from the first portion of the paper substitute check, the computer-implemented method comprising: (a) electronically on an image capture device capturing an image of the paper substitute check; (b) reading from the paper substitute check the first MICR codeline which is printed on the first portion of the paper substitute check; (c) reading from the captured image of the paper substitute check the second MICR codeline which is printed on the second portion of the paper substitute check; and (d) electronically on a microcomputer comparing the first MICR codeline read in step (b) and the second MICR codeline read in step (c) to determine if the first MICR codeline which is printed on the first portion of the paper substitute check and the second MICR codeline which is printed on the second portion of the paper substitute check match.
