Automated banking system for making change on a card or user account

摘要

An unattended banking machine such as an ATM machine has a payment acceptor for accepting payment from the machine user and for determining the amount of payment from the user. A calculator determines the transactional difference between the amount of the transaction and the payment by the user. In ATM machines service fees may be charged to the ATM user for issuing a money order or for a wire transfer that are not in even multiples of the smallest denomination of the currency being dispensed by the ATM machine. The preferred cash dispenser has only bills of different denominations and no coins. To pay the transactional difference without the use of very small denomination currency and/or coins the transactional difference is divided into a cash payment portion which is dispensed in bills from the machine's cash dispenser. The remainder of the transactional payment is paid electronically to the ATM user either on a card, such as a smart card, or into the user's ATM account as an electronic remainder payment portion. The ATM machine includes a card reader and card writer to add the electronic payment portion to the balance on the card. The ATM machine may perform a number of other transactions such as cashing a check, paying a bill, and purchasing an item.
