Automated Teller Machine (ATM): An Overview
Automated Teller Machines (ATMs) have become an essential component of modern banking infrastructure, enabling customers to perform basic financial transactions without visiting a bank branch. Introduced to simplify cash access and reduce dependence on teller services, ATMs now play a critical role in delivering convenient, round-the-clock banking services across urban and rural areas.
An ATM is an electronic banking outlet that allows users to complete transactions such as cash withdrawals, balance inquiries, fund transfers, mini statements, and bill payments using a debit or ATM card. Most machines operate through secure connections with banking networks, ensuring real-time processing and authentication. The integration of personal identification numbers (PINs), encryption technologies, and increasingly biometric verification has enhanced transaction security and customer trust.
