This project is to develop an application software for atm having customer console(keyboard and display) for interaction with the customer, a printer for printing customer receipts, and a key-operated switch to allow an operator to start or stop the machine.

The atm must provide the following service to the customer:

1.) A customer must be able to make a cash withdrawal from and suitable account, in multiples of $20.00. Approval must be obtained from the bank before cash is dispensed.

2.)A customer must be able to make a deposit to any account, consisting of cash and /or checks in an envelope. The customer will enter the amount of the deposit into the atm, subject to manual verification when the envolope is removed from the machine by and operator. Approval must be obtained from the bank before physical accepting the envolope.

3.)A customer must be able to make a balance inquiry of and linked account.

A customer must be able to abort a transaction in progress by pressing the cancel key instead of responding to a request from the machine.
