what is atm pin no

The ATM PIN stands for Personal Identification Number. It is a secret, typically four-digit numerical code that serves as a security password to authenticate you as the rightful cardholder. You must enter this code at an Automated Teller Machine (ATM) or point-of-sale terminal to withdraw cash, check your balance, or complete other transactions. Its main purpose is to prevent unauthorized access and protect your bank account from fraud, ensuring that even if your card is lost or stolen, it cannot be used without this private code.
