Draw an activity diagram of cash withdrawal using an ATM machine. The diagram must include three swim-lanes (i.e., customer, ATM, and ATM owing back). For a transaction, the machine validates pin, checks if the amount is a multiple of $20, checks for daily withdrawal limits, and checks if the customer’s account belongs to an out-of- network bank. An out-of-network customer must acknowledge paying $3 processing fees before proceeding with a transaction.
