What is atm definition?

ATM, short for Automated Teller Machine, is an electronic banking device that is used by customers of financial institutions to perform various banking transactions such as depositing or withdrawing cash, making balance inquiries, paying bills, and transferring funds. It is a self-service machine that operates 24 hours a day, seven days a week, and can be accessed with a bank-issued card, also known as an ATM card or debit card, and a personal identification number (PIN). The first ATM was introduced in 1967 by Barclays Bank in London, and since then, it has become a popular and convenient way for people to access their money and perform financial transactions. ATMs are now available across the world, making banking faster, easier, and more accessible to customers.
