A method of processing checks includes obtaining first information relating to the checks that is compiled by an operator using a calculator, such as by scanning a calculator tape, wherein the first information includes a first number of first dollar amounts, each of which corresponds to a respective one of the checks. The method further includes scanning the checks to create a plurality of check images, obtaining from the check images a second number of second dollar amounts, each corresponding to a respective one of the check images, determining whether the first number is equal to the second number, and providing an error indication if the first number does not equal the second number (which is an indication that a misfeed has occurred).
