Section 3 (Finance) of the PFRDA Grade A syllabus, RBI Grade B (ESI & FM), and SEBI Grade A explicitly test ‘Financial Inclusion, FinTech, Digital Payments, and Alternate Sources of Finance’. India’s Digital Public Infrastructure (DPI — the ‘India Stack’) comprises three foundational layers: Identity (Aadhaar), Payments (UPI, IMPS, RuPay, AePS, Bharat Connect/BBPS), and Data Empowerment & Credit (DEPA, Account Aggregator [NBFC-AA], Unified Lending Interface [ULI], OCEN, and ONDC), alongside the RBI’s Central Bank Digital Currency (Digital Rupee — e₹-W and e₹-R under Section 22 of the RBI Act, 1934) and Financial Sector Regulatory Sandboxes.

1. Central Bank Digital Currency (CBDC — Digital Rupee e₹) & UPI Milestones

Following the insertion of Section 2(aiv) (“bank note includes a bank note issued in digital form”) and Section 22A in the Reserve Bank of India Act, 1934 via the Finance Act, 2022, the RBI launched India’s sovereign Central Bank Digital Currency (Digital Rupee or e₹):
