UPI Now Processes More Transactions Per Day Than Visa: What the UK Can Learn From India

UPI Now Processes More Transactions Per Day Than Visa: What the UK Can Learn From India

In 2016, India launched a payments system that most Western analysts quietly dismissed. The country had 300 million people without bank accounts, unreliable internet infrastructure in rural areas, and a cash dependency so deep it was practically cultural. The idea that India could leapfrog the established card networks seemed, at the time, optimistic at best.

Nine years later, UPI, the Unified Payments Interface, processes more transactions in a single day than Visa does globally.

Let that sit for a moment.

Visa, the payments giant with 4.3 billion cards in circulation and merchant acceptance in over 200 countries, is being outpaced in volume by a system that did not exist a decade ago. According to the National Payments Corporation of India (NPCI), UPI recorded approximately 17.16 billion transactions in January 2025 alone. That works out to roughly 554 million transactions per day across that month, with peak days exceeding 640 million. Visa, by comparison, processed approximately 276 million transactions per day in its most recently reported quarter (Q1 FY2025). The gap is not narrow. It is enormous.

This is not a story about India catching up. It is a story about what happens when a country decides to build payment infrastructure as national infrastructure, and gets the architecture right from the start.

How UPI Actually Works

UPI is not an app. This is a common misconception. It is a protocol, a set of open standards built on top of India's Immediate Payment Service (IMPS) and developed by the NPCI, a not-for-profit entity set up under the Reserve Bank of India. Think of it as the plumbing. PhonePe, Google Pay, Paytm, and dozens of other apps sit on top of it, competing fiercely for users whilst sharing the same underlying infrastructure.

The mechanic is elegantly simple. Every user gets a Virtual Payment Address (VPA), something like yourname@bankname. To send money, you enter a VPA, a mobile number, or scan a QR code. The money settles in seconds, 24 hours a day, 365 days a year, directly between bank accounts. No card required. No intermediary holding funds. No merchant discount rate eating into the transaction.

For most small transactions in India, the cost to merchants is effectively zero.

The Numbers That Should Make UK Policymakers Uncomfortable

UPI's growth curve is not just impressive; it is structurally significant. Consider the trajectory:

• 2017 (first full year): 1.8 billion transactions
• 2020: 22 billion transactions
• 2022: 74 billion transactions
• 2024: 172 billion transactions

That is a near-hundredfold increase in seven years. The World Bank and BIS CPMI data consistently cite India as the single largest real-time payments market by volume, accounting for roughly 49% of all real-time transactions globally in 2023.

For context, the UK processed approximately 3.9 billion Faster Payments transactions in 2023 according to UK Finance. The UK system is excellent. It is just operating at a completely different scale, serving a population roughly one-twentieth the size of India's. The comparison is not about shame; it is about ambition.

India made UPI work not by being richer, more technologically sophisticated, or better regulated than the UK. It worked because of three specific design decisions the UK has only partially replicated.

Three Design Decisions That Made UPI Unstoppable

1. Interoperability Was Non-Negotiable

UPI was built on the principle that every bank, every wallet, every app must connect to the same rails. There was no opt-in period, no phased commercial negotiation, no incumbent veto. The NPCI mandated participation. In the UK, Faster Payments has broad but not universal coverage, and the New Payments Architecture (NPA) programme, overseen by Pay.UK, has faced repeated delays. The Payment Systems Regulator published its review of retail payments in 2023 noting concerns about the pace of NPA delivery. Mandated, universal interoperability changes the game entirely.

2. Zero MDR for Small Merchants

In 2020, the Indian government abolished the Merchant Discount Rate on UPI transactions. Merchants pay nothing to accept a UPI payment. Nothing. The cost is borne partly by the government through subsidies to banks and partly by the structural efficiency of a system that does not involve card networks, issuer banks, and acquirer banks all taking their respective cuts.

For a UK small business owner accepting card payments today, the all-in cost typically runs between 1.5% and 2.5% per transaction depending on the card type and provider. On a 50-pound sale, that is between 75 pence and £1.25 gone before you have paid for stock, rent, or staff. Multiply that across a year of trading and it is a meaningful number. The PSR's market review into card acquiring fees, which concluded in 2023, acknowledged that merchants, particularly small ones, have limited bargaining power. Zero-cost infrastructure would change this calculus entirely.

3. QR Codes as Universal Acceptance Points

India standardised on a single QR code format called Bharat QR, which any UPI app can scan. A street vendor can print a QR code on a piece of paper and accept digital payments from any of 350 million UPI users without a card terminal, a point-of-sale device, or a merchant account in the traditional sense. The acceptance infrastructure essentially democratised overnight.

In the UK, QR-based payments remain fragmented. PayPoint, Barclaycard, and various fintech providers have their own implementations, but there is no universal standard that allows a customer to scan and pay regardless of their bank or app.

What the UK Has Built, and What It Has Not

Britain is not starting from zero. Faster Payments, launched in 2008, was genuinely ahead of its time. The UK was processing near-instant bank transfers years before most European countries. The FCA's regulatory sandbox, launched in 2016, has incubated dozens of payment innovations. Open Banking, mandated by the CMA following PSD2, has created the technical foundation for account-to-account payments that could theoretically replicate UPI-style flows.

The missing piece is adoption. Open Banking-powered payments processed approximately 11.7 million payments in January 2024 alone according to Open Banking Limited, up 72% year-on-year. That is meaningful growth. But compared to UPI's 640 million daily transactions, it illustrates the scale of the cultural and structural gap.

The reasons are multiple. UK consumers trust cards. They have fraud protections on cards that do not automatically apply to bank transfers. Contactless payments work frictionlessly at point of sale. The incentive to switch, for the average consumer, is not yet compelling enough.

What UK Businesses Can Actually Do Right Now

The honest answer is that you cannot single-handedly accelerate the NPA or force the PSR to mandate zero-cost bank transfer acceptance. But there are practical moves worth considering today.

Explore Open Banking payment options. Providers including Volt, TrueLayer, and Yapily offer account-to-account payment products that settle via Faster Payments. For higher-value transactions, the economics can be significantly better than card. If you run a B2B business or take large one-off payments, the saving over card MDR can be substantial.

Understand your true cost of acceptance. Most small business owners know their headline card rate but not their effective rate across all transaction types. American Express, commercial cards, and cross-border cards all carry premium fees. A proper audit of your merchant statement often reveals costs that can be reduced immediately by switching to a transparent, interchange-plus pricing model.

Watch the PSR's Variable Recurring Payments (VRP) consultation closely. VRP is the UK's most promising route to UPI-style recurring and scheduled payments via Open Banking. The PSR published its consultation on expanding VRP beyond sweeping in late 2023. If mandated broadly, this could fundamentally change subscription and utility payment economics for UK businesses.

Do not dismiss QR codes. They have failed twice in the UK consumer market, but the infrastructure, the smartphones, the cameras, the bank apps that can initiate payments, is now genuinely there. A third wave, driven by Open Banking QR-initiated payments, is not implausible within a three-year horizon.

The Bigger Picture

The UPI story is ultimately about what happens when a government treats payment infrastructure as a public good rather than a commercial opportunity. India's NPCI is not a bank. It is not a card network. It does not extract rent from every transaction. It provides the rails and lets competition happen at the application layer.

The UK's equivalent conversation is happening, slowly, inside the PSR, Pay.UK, and the Bank of England's payments oversight work. The New Payments Architecture will, when it eventually arrives, create the technical foundation for a more open, more competitive market. But architecture without ambition is just plumbing.

India did not get to 640 million daily transactions by accident. It got there by deciding that cost-effective, universally accessible digital payments were a national priority, and then building the institutions and mandating the participation to make it happen.

The UK has the institutions. The question is whether it has the ambition.
