Key facts about UPI

1️⃣ World's Largest Retail Real-Time Payment System

India's UPI is the world's leading real-time payment system, 

surpassing Visa in daily transactions and accounting for nearly 

50% of global real-time digital payments in 2023.

 It is a major tool of India's "soft power" and 

Digital Public Infrastructure (DPI) diplomacy. 

It is already live in 7+ countries, including the 

UAE, Singapore, France, Bhutan, Nepal, Mauritius, and Sri Lanka.

 2️⃣ True Interoperability and "Open-Loop" System

Unlike closed-loop wallets, UPI allows a single mobile application 

to access multiple bank accounts and facilitates instantaneous, 24/7, 

peer-to-peer (P2P) and person-to-merchant (P2M) transactions.

 It revolutionised digital payments by eliminating the need to 

share bank details (using a Virtual Payment Address - VPA) and 

integrating with the JAM Trinity (Jan Dhan-Aadhaar-Mobile) to 

promote financial inclusion, especially for small merchants.

UPI is built on the IMPS [Immediate Payment Service] infrastructure.

But it provides a simpler interface.

It uses QR codes and VPA instead of account numbers.

3️⃣ Innovative Features Driving Financial Inclusion (UPI Lite, 123PAY, Credit Line)

NPCI (National Payments Corporation of India) has constantly innovated to 

include everyone, such as UPI 123PAY for feature phone users (non-smartphone) 

and UPI Lite for low-value offline payments.

These features bridge the digital divide. 

Other critical innovations include linking Ru Pay credit cards to UPI, 

conversational voice payments, and the "UPI Circle" for delegated payments.
