ABSTRACT:
A teller machine is capable of modifying information stored within a secondary memory when the operator realizes a mistake even after he has completed transactions and placed information with respect to these transactions into the secondary memory. In the teller machine, a primary memory stores numerical information representative of amounts of money after each transaction and a secondary memory stores cumulative amounts of money for all transactions.
