Discuss the challenges in monitoring merchant turnover thresholds in a digital payments ecosystem and their implications for financial inclusion.

NPCI's new UPI framework, effective 15 October 2026, levies a 0.4% Merchant Discount Rate on person-to-merchant payments above ₹2,000, while exempting small merchants receiving up to ₹1 lakh per month through UPI QR codes [1]. This turnover-based exemption is socially sound in intent, but it converts a simple payment rail into a rule that must be continuously measured — and measurement, not the rate, is where the design strains.

Challenges in monitoring turnover thresholds

• Aggregation problem: a merchant may hold QR codes across several apps and bank accounts; unless turnover is pooled across providers, two acquiring banks can classify the same shop differently [3].
• Real-time tracking burden: status changes mid-month, requiring banks to track running turnover and switch pricing dynamically — a compliance load on acquirers, not on NPCI [3].
• Thin-sliver arbitrage: twin thresholds — ₹2,000 per transaction and ₹1 lakh monthly — invite splitting of bills or diverting receipts to cash to stay below the line.
• Verification without intrusion: turnover captured only on UPI rails is a partial picture of actual business, yet deeper scrutiny raises data-privacy concerns.

Implications for financial inclusion

• Acceptance risk at the last mile: ambiguity may push marginal merchants to prefer cash, reversing the digitisation drive that zero-MDR since 2020 was built to create.
• Weakened cost support: the ₹1,500 crore Incentive Scheme for low-value BHIM-UPI (P2M) already pays acquiring banks 0.15% on small-merchant transactions up to ₹2,000, with 20% released only on meeting uptime and decline-rate norms [2]; letting it lapse would strand exactly the merchants the exemption protects.
• Misinformation vulnerability: PIB has earlier had to reject as "completely false" claims of GST on UPI payments above ₹2,000 [4] — threshold rules are easily misread by small users.

Simplicity is itself an inclusion policy. Publishing a clear, cross-app turnover computation method through NPCI's FAQ route [3], sustaining the performance-linked incentive [2], and testing outcomes against the RBI Digital Payments Index [5] would let cost recovery proceed without pricing the smallest merchant out of the digital economy.
