ATM scenario from Object-Oriented Modeling and Design, by J.Rumbaugh, 1991 The ATM asks the user to insert a card The ATM accepts the card and reads its serial number The ATM requests the password The ATM verifies the serial number and password with the consortium, the consortium checks it with the bank and notifies the ATM of acceptance The ATM asks the user to select the kind of transaction (withdrawal, deposit, …). The user select withdrawal The ATM asks for the amount of cash The ATM verifies that the amount is within predefined policy limits and asks the consortium to process the transaction. The consortium passes the request to the bank, which eventually confirms success and returns the new account balance The ATM dispenses cash and asks the user to take it The ATM asks whether the user wants to continue, the user indicates no The ATM prints a receipt, ejects the card, and asks the user to take them The ATM asks a user to insert a card
