what is bhim upi pin

A UPI PIN is a 4 or 6-digit secret code used as the primary authentication credential to approve and complete financial transactions. It is a mandatory security feature that a user sets up to authorize fund transfers, person-to-person payments, and merchant transactions through the UPI platform. This unique code ensures that every payment is secure, as no transaction can be processed without the correct PIN. To set this security code initially, the user must provide the last six digits and the expiry date of their debit card linked to the bank account.
