UPI
Also known as: Unified Payments Interface
India's instant, free system for sending money between bank accounts using a phone.
UPI lets you transfer money instantly, 24x7, straight between bank accounts using apps like GPay, PhonePe, and Paytm.
It is free for regular person-to-person and most merchant payments, and works with a simple ID or QR code.
It has made cash and cards optional for everyday spending across India.
For example
Split a dinner bill by scanning a friend's UPI QR and sending ₹500 instantly, with no fees and no card details needed.
