What is the use of UPI?

The Unified Payments Interface (UPI) is a system for instant, secure, and free mobile money transfers. It facilitates various financial transactions, making digital payments easier for users. UPI also offers smooth digital payment options like UPI Vouchers for corporate gifts and government programs. Furthermore, with UPI Global Acceptance, Indian users can make QR code-based payments at select international merchant stores using a UPI-powered application like Paytm.
