What does UPI PIN mean?

A UPI PIN (Unified Payments Interface Personal Identification Number) is a secure 4 or 6-digit numeric code used to authorize all bank transfers through UPI-enabled applications. It acts as a digital password unique to each linked bank account, ensuring that only the account holder can approve a transaction. You must enter this PIN every time you send money, pay bills, or scan a QR code to complete a payment. For security, it is essential to keep your UPI PIN confidential and avoid sharing it with anyone.
