ATM or an Automated Teller Machine is an electronic machine installed at various places to help people perform financial or banking transactions themselves, without visiting the bank or without the assistance of a bank representative. Anyone with a credit card or a debit card can access cash at the ATM. 

Few ATMs allow only cash withdrawal and bank balance checking facilities, while others allow a variety of banking transactions like deposits, withdrawals, bill payments, fund transfers, etc. A small fee is charged by some of the ATMs. ATMs provide 24*7 access anywhere, thereby easing financial transactions by a common man.
