Abstract: A system and method to produce and use new bank checks with magnetized strips (30) and/or storage chips (33) to avoid forging in the checks and to confirm immediately upon introducing them for negotiation, whether or not sufficient funds are available. The bank check system comprises issued bank checks whose front and rear faces carry imprinted visible data (11-21) and a magnetic strip (30) and/or storage chip (33) containing stored encoded data readable by a reader so it can be checked for conformity with the visible data (11-21) to detect any unauthorized alterations to the check. The visible data (11-21) and stored encoded data include an identification of a check (19), account, drawer (15) and bank (16). The new checks include checks with a maximum value, or a fixed value that is pre-paid and blocked in the drawer's account, and “ordinary” checks, enabling to check whether the checks to be paid with a sufficient blocked amount.

Abstract: 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).
