This diagram visually represents the sequence of interactions between a customer and an Automated Teller Machine (ATM) during a transaction. It starts with the customer inserting an ATM card, followed by the system prompting the customer to enter a PIN. The account is then checked against the bank's server database for validation. If the information is accepted, the customer is prompted to enter an amount for the transaction, which is then validated again by the bank server before updating the database. This template is an excellent tool for understanding the ATM transaction process's step-by-step workflow.
