Aims & Objectives

What is an ATM Machine?

An Automated Teller Machine (ATM) is an electronic banking outlet, which allows customers to complete basic transaction without the aid of a branch representative or a teller

ATM CardAn ATM card is any payment issued by a financial

institution that enables a customer to access an ATM machine in order to perform transaction.

Advantages• Can use ATM machines at any time without accessing into

a bank.• ATMs offer the convenience of multiple locations.• Your ATM card is protected by a PIN. • You don’t need to fill out any slips to do your task.• ATMs are faster than going to the bank – no long lines.• One can withdraw cash at ATMs in foreign countries.

Disadvantages• There must be system down failures.• You might forget your PIN number.• Risk of robbery when you leave the ATM.• Fees charge to use ATMs of other banks can become

expensive.

printf("\t\t\tEnter your PIN:"); scanf("%d",&pin); do{ if (pin==12345)

{ start(a); printf("\t\t\tSelect you operation: "); scanf("%d",&a); ; else { if (i<4) {printf("\t\tEnter valid PIN!\n");

Enter your pin:
