A self-service check cashing system and method which performs preliminary tests on a check to reduce queue length at attendant check cashing stations. An example method includes obtaining an amount of a check from a customer by the self-service terminal, obtaining information from an image of a check by the self-service terminal, performing a plurality of tests by the self-service terminal, including tests using the information from the image to determine whether the check was properly completed; and displaying instructions to the customer by the self-service terminal to go to an attendant terminal to complete a second phase of the check cashing transaction when the self-service terminal determines that the test results were positive.
