An ATM (Automated Teller Machine) controller is a specialized computer system that manages the operations of an ATM, including transaction processing, user interface, and communication with financial networks. It functions by receiving input from the user through the ATM interface, validating the user's credentials, and processing requests such as cash withdrawals or balance inquiries. The controller communicates with the bank's servers to authorize transactions and ensures security protocols are followed. Additionally, it manages hardware components like the cash dispenser, card reader, and receipt printer.
