The Unified Payments Interface (UPI), a mode of instantaneous payment using mobile phones, has captured the imagination of people around the world as a preferred way of going about buying and selling commodities and services of all kinds. Today almost half the adult population of India uses UPI for making payments on person-to-merchant (P2M) and person-to-person (P2P) transactions, thereby replacing king cash.

Implications of digital payments The accelerating pace of adoption of digital payments has far-reaching consequences for the economy. It transforms the ecosystem of trade and commerce, consumption, saving and investment, acquisition and holding of assets, which in turn brings about far-reaching changes in all aspects of the socio-economic landscape, injecting efficiency.

Everybody, including the government, benefits. Hence, promotion of digital payments makes ample sense.

How UPI evolved The National Payments Corporation of India (NPCI), as an umbrella organisation, was set in motion as part of the Vision Document 2005-08 of the Reserve Bank of India (RBI) and UPI was launched by the NPCI in 2016 as a part of a journey – ATM, IMPS and then UPI. UPI has completely transformed and revolutionised the way we make payments.

Factors behind UPI revolution When a customer initiates a UPI payment, his bank account is debited and the receiver’s bank account is credited through a process known as the clearing and settlement system and an interface like BHIM. What makes UPI attractive is its use by customers at no cost, along with its convenience.

The NPCI, being a not-for-profit company, backed by the RBI, Indian Banks’ Association and the government, could make this possible. , also developed ecosystems like QR codes, integrating merchants and customers and providing them sound boxes to let them know whether payments have been credited to their accounts.

4% MDR on UPI transactions worth Rs 2,000 or more on person-to-merchant transactions from 15 October 2026, raising around Rs 20,000 crore, according to a rough estimate. This will be used to pay banks and FinTech companies to compensate them for helping spread digital payments.

Why do banks need MDR? A bank is required to provide cash deposit and withdrawal facilities free of cost from time immemorial.

As customer deposits are the most important raw material for lending by banks, they had to allow cash withdrawals as a service to these customers. This is how modern banking evolved.
