Q.4) We all are familiar with the Bank ATM machine that we use to withdraw money. In this situation, you are required to add the functionality of “Deposit Money using the ATM machine”.

Write a formal Use Case document for the process described below. Describe the success scenario and the alternate scenarios. [7 points] A deposit transaction is started from within a session when the customer chooses deposit from the menu of possible transaction types. The customer chooses a type of account to deposit to (e.g. checking) from a menu of possible accounts, and then chooses a dollar amount by typing it on the keyboard. The system sends the customer’s card number, PIN, chosen account and amount to the bank, which either approves or disapproves the transaction. If the transaction is approved, the machine accepts an envelope from the customer containing cash and/or checks and then issues a receipt. (If the customer does not insert the envelope within a specified period of time, this operation times out and the deposit transaction is aborted). If the transaction is disapproved due to an incorrect PIN, the Incorrect PIN extension is executed. All other disapprovals are reported to the session, which initiates the Failed Transaction Extension. The bank is notified whether or not an approved transaction was completed in its entirety by the machine; if it is completed then the bank completes crediting the customer’s account for the amount – contingent on manual verification of the deposit envelope contents by an operator later.
