Automated teller machines (ATMs) are electronic devices that allow people to access their bank accounts and perform various financial transactions without the need for a bank teller. Users can withdraw cash, deposit money, check account balances, and transfer funds using a debit or credit card. ATMs are typically available 24/7, providing convenience for banking needs. These machines are equipped with a screen, keypad, and card reader, and they often have a cash dispenser. ATMs are found in various locations, such as banks, shopping centers, and airports, making it easy for users to find one nearby.
