Automatic Teller Machine (ATM)

The ATM is a terminal of the bank's computer network and is operated by a customer himself through a VDU and a keyboard. The customer is given a plastic card at the time of opening his account. The name of the account holder and the account number are magnetically coded on the card. The customer is also given a PIN (Personal Identification Number) which is only known to him. When the customer inserts his card in the ATM, it checks the magnetically coded data and identifies the customer. He then types in  his PIN and the amount is withdrawn. The ATM checks the balance and gives out the currency along with a statement of the transaction. The amount gets debited from the account.
