Please draw level 0 and context diagram Question 12 Not yet answeredmachine reads card number and its expiration date. If the card has expired, the ATM machine shows refusal Points out of 33.00 information to customer and cancels the transaction. Otherwise, the customer is required to enter PIN code. The To withdraw money at an ATM machine, a customer inserts her ATM card into the machine. Then the ATM ATM then compares the PIN code entered with the one stored in customer file to see if they match. If they don't match, card is returned and a refusal message is shown to the customer. If they match, the customer is then able to enter the amount of cash to withdraw. ATM retrieves the customer's balance information from the account file and compares it with the amount to withdraw entered by the customer. If account balance is greater than the amount to withdraw, cash is dispensed, balance is calculated and updated in the account file as well as the customer file, and a receipt is printed. If account balance is less than the amount to withdraw, the customer is asked to reenter the amount up to two more times. If valid amount to withdraw has not been entered after two more attempts, the transaction is cancelled and customer file is updated. Remove flag Use Visio to draw context and level-0 diagrams.
