UPI transactions reached a record 24.51 billion in August 2026, capturing 77.3% of retail payment share. As physical cards decline, banks and fintechs face a structural revenue shift, balancing the high engagement of QR payments against the significantly lower fee income compared to traditional card swipes.
The Indian retail payments landscape has shifted decisively toward digital instant payments, with the Unified Payments Interface (UPI) hitting a record 24.51 billion transactions in August 2026. These transactions totaled Rs 29.82 lakh crore, cementing UPI's position as the primary method for everyday retail spending.
Data from July 2026 shows that UPI’s share of person-to-merchant (P2M) transactions has climbed to 77.3%, up from 74.9% a year earlier. In contrast, the utility of physical plastic cards is eroding rapidly. Debit cards, once the standard for store-based transactions, saw their share in merchant payments drop to just 3.2% as of July 2026, compared to 3.9% in the same period last year. For the average consumer, the speed of a QR code scan has largely replaced the need to carry physical debit cards or wait at card terminals.
Credit cards are undergoing a different transformation. While their share in daily merchant payments also dipped to 17.7% in July 2026, the product remains central to high-value purchases and e-commerce. To stay relevant, credit card issuers are increasingly integrating their offerings with the UPI ecosystem. By linking RuPay credit cards to UPI applications, banks are allowing users to tap into credit lines directly through the QR infrastructure, bypassing the need for a physical card at many points of sale.
For investors and market observers, this transition carries specific business implications. Traditional card swipes typically generated a Merchant Discount Rate (MDR)—a fee paid by merchants to banks and payment providers—which served as a consistent revenue stream. In the current UPI-dominated model, the vast majority of transactions, particularly smaller ones, are processed without MDR. This creates a challenging environment for banks and payment service providers who must manage massive transaction volumes and infrastructure costs while facing pressure on fee-based income.
The introduction of 'Credit-on-UPI' is a strategic attempt to bring MDR back into the ecosystem, as transactions above Rs 2,000 on credit lines are subject to merchant fees. However, this creates a new friction point: merchant resistance. Smaller merchants may be hesitant to accept credit-based UPI payments if they are required to pay an MDR of 1.1% to 2%, potentially limiting the widespread adoption of credit on QR codes.
Furthermore, the sector faces risks from high market concentration. A few large players, such as PhonePe, Google Pay, and Paytm, process the overwhelming majority of UPI volume, leaving the wider ecosystem dependent on their performance and regulatory compliance. As the industry moves forward, the key monitorable for investors will be any regulatory updates regarding MDR structures and transaction limits, which could significantly impact the profitability of both public and private sector banks involved in digital payments.
