ISTQB Question Dumps For Software Testing -  Part  24


An ATM has been specified to work in the following way:

Enter a card and if the card is invalid reject the card and exit system. If it is a valid card then enter a PIN number. Check to see if the PIN is invalid – if it is then display a message ‘invalid pin number, please re-enter’. If 3 attempts are made with an invalid pin then the machine keeps the card. If it is a valid PIN then the user can select one of the following transactions:
• Cash Withdrawal without receipt
