Introduction

India operates one of the world's largest digital payment ecosystems, built on interoperable systems managed largely by the National Payments Corporation of India (NPCI) under RBI's oversight. Each system serves a distinct transaction need.

NPCI — The Common Thread

The National Payments Corporation of India (NPCI), promoted by RBI and IBA, operates UPI, IMPS, RuPay, BBPS, and AEPS — making it the backbone institution for most of India's retail digital payment infrastructure. NEFT and RTGS, by contrast, are operated directly by the RBI.
Q. Which payment system requires a minimum transaction amount of ₹2 lakh?
RTGS (Real Time Gross Settlement) is designed for high-value transactions and has a minimum transaction amount of ₹2 lakh, with no upper limit.
⚠️ Key Insight: NEFT and RTGS are both operated by the RBI directly, while UPI, IMPS, RuPay, AEPS, and BBPS are operated by NPCI — this operator distinction is a frequently tested point separate from the transaction-limit differences.
