Automated Teller Machines (ATMs) are electronic banking outlets that allow customers to perform basic financial transactions without the need for a human teller. ATMs are typically located in public areas such as shopping centers, airports, and convenience stores, as well as within bank branches. These machines are designed to provide customers with quick and convenient access to their bank accounts, allowing them to withdraw cash, deposit checks, transfer funds, and check their account balances. ATMs are equipped with a range of features that make them easy to use, including touch screens, keypads, and card readers. Customers can access their accounts by inserting their bank card into the machine and entering their personal identification number (PIN). Once authenticated, customers can select the transaction they wish to perform from a menu of options displayed on the screen. ATMs are an essential part of the modern banking system, providing customers with 24/7 access to their accounts and reducing the need for human tellers. They are also an important tool for banks, allowing them to reduce their operating costs and improve their efficiency.
