what is green pin in atm

The Green PIN is a digitally generated, eco-friendly alternative to the traditional paper PIN mailer sent by banks. It is an instant One-Time Password (OTP) sent to a customer's registered mobile number. This secure OTP allows the cardholder to conveniently set or reset their own 4-digit Personal Identification Number (PIN) for their debit or credit card at any bank's ATM, through net banking, or a mobile app. This process enhances security and eliminates paper waste.
