An ATM (Automated Teller Machine) transaction allows users to access their bank accounts electronically. Customers can perform various functions, such as withdrawing cash, depositing money, checking account balances, and transferring funds between accounts. These transactions are typically completed using a bank card and a personal identification number (PIN) for security. ATMs are widely available in various locations, including banks, shopping centers, and airports. They provide a convenient way for individuals to manage their finances without needing to visit a bank branch. Most ATMs are connected to a bank network, enabling users to access their accounts from different locations.
