NEFT, RTGS & UPI
Introduction
Electronic payment systems form the backbone of modern banking in India. NEFT (National Electronic Funds Transfer), RTGS (Real Time Gross Settlement), and UPI (Unified Payments Interface) are the three most important payment channels that every banking professional must understand. This topic is heavily tested in the JAIIB exam covering operational features, settlement mechanisms, timings, limits, and regulatory aspects.
NEFT — National Electronic Funds Transfer
Overview
- Managed and operated by the Reserve Bank of India (RBI)
- Electronic fund transfer system for one-to-one transactions
- Available 24x7x365 (round the clock since December 2019)
Settlement Mechanism
- Deferred Net Settlement (DNS) — transactions are settled in half-hourly batches
- Transactions are accumulated and settled in batches, not individually
- Settlement happens across all banks simultaneously through RBI
Key Features
| Feature | Detail |
|---|---|
| Settlement | Half-hourly batch settlement |

| Charges | No charges for savings account holders (RBI directive) |
| Mode | Online (internet/mobile banking) and offline (branch) |
NEFT Process Flow
- Remitter initiates transfer through bank (online or branch)
- Originating bank prepares and sends the message to its NEFT Service Centre
- Messages are forwarded to the NEFT Clearing Centre (operated by RBI)
- RBI sorts transactions bank-wise and destination-wise
- Beneficiary bank credits the amount to the beneficiary's account
Requirements for NEFT
- Beneficiary's name, account number, and bank
- IFSC code (Indian Financial System Code) of the beneficiary's bank branch
- Amount to be transferred
RTGS — Real Time Gross Settlement
Overview
- Managed and operated by the Reserve Bank of India (RBI)
- Designed for high-value, time-critical fund transfers
- Available 24x7x365 (round the clock since December 2020)
Settlement Mechanism
- Real-Time Gross Settlement — each transaction is settled individually and immediately
- No batching or netting — funds move in real-time
- Settlement is on a gross basis (full amount, not net)
Key Features

RTGS Process Flow
- Remitter instructs the bank to transfer funds
- Originating bank sends the payment instruction to RBI
- RBI debits the originating bank's account and credits the beneficiary bank's account in real time
- Beneficiary bank credits the customer's account
