6. The Requirements Statement for an ATM system is provided as follows:
The ATM must be able to give the subsequent services to the customer:
i) A customer must be able to make a cash withdrawal from any suitable account
linked to the card, in multiples of $20.00. Approval must be found from the
bank before cash is dispensed.
ii) A customer must be able to make a deposit to any account linked to the card,
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

found from the bank before physically accepting the envelope.
iii) A customer must be able to make a transfer of money ranging from any 2 accounts
linked to the card.
iv) A customer must be able to make a balance inquiry of any account linked to the
card.
