The full form of ATM is Automated Teller Machine. An ATM is an electronic machine used for financial transactions, and it allows customers to withdraw cash, check their balance, transfer funds, and perform other basic transactions without the aid of a bank representative or teller. ATMs are convenient, allowing consumers to perform quick self-service transactions such as deposits, cash withdrawals, bill payments, and transfers between accounts. Anyone with a credit card or debit card can access cash at most ATMs, either in the U.S. or other countries. Different banks provide their ATM services by installing cash machines in different parts of the country, and you can withdraw money from any of these machines irrespective of whether or not you are an account holder in the same bank.
