India Stack and DPI

Digital Public Infrastructure (DPI) — open, interoperable digital rails — underpins it all. The India Stack has three layers: identity (Aadhaar/e-KYC), payments (UPI) and data (the Account Aggregator framework, DigiLocker) — enabling presence-less, paperless, cashless services and the JAM trinity for direct benefit transfers.

Fintech and UPI

UPI has made India the world leader in real-time digital payments. Fintech now spans payments, digital lending, insurtech, wealthtech and neobanking. New layers include the Account Aggregator (consent-based data sharing for credit), the Open Network for Digital Commerce (ONDC) (democratising e-commerce), and the pilot CBDC (digital rupee).

Opportunities and risks

The digital economy boosts financial inclusion, formalisation, efficiency and new business models. Risks include data privacy and security (addressed by the DPDP Act, 2023), cyber fraud, the digital divide, algorithmic/predatory lending, and concentration — requiring strong regulation and digital literacy.
