Abstract: An easy cash drawing system, Automated Teller Machine (ATM) has become an integral part of our society. For withdrawal service, existing ATM machines asks only how much money do you want to withdraw after the user authentication. It does not ask what denominations the customer wants. So implementing custom denomination request in an ATM withdrawal is an added advantage to the customer. It avoids the overhead of a customer by giving custom denomination for small and large amount withdrawals.
