This UML sequence diagram depicts the ATM cash replenishment and maintenance workflow, highlighting interactions between the Bank Cash Officer, Security Guard, ATM Machine, Bank Server, and Maintenance System. The process begins with arrival at the ATM location and a request for access authentication.
Depending on the security verification, access is either granted or denied. Once authorized, the cash vault is opened, cassettes are loaded, and the ATM inventory is updated. Alternatives handle mismatched inventory or hardware issues. The class diagram also shows diagnostics, scheduling of maintenance tasks, and vault closure. Communication between actors ensures secure operations, accurate updates, and proper maintenance logging.
