Which UPI is free?

All Unified Payments Interface (UPI) services are free for basic transactions, according to official sources. You can send money, receive payments, or pay merchants directly from your bank account without any charges for peer-to-peer and peer-to-merchant transactions. This is a core benefit of the service, simplifying the payment process and allowing instant, real-time fund transfers. Apps that facilitate UPI, such as Paytm, adhere to this no-fee structure for everyday use.
