Payment systems (NPCI - National Payments Corporation of India, 2008 - runs most retail rails):
| System | Nature | Key facts |
|---|---|---|
| NEFT | National Electronic Funds Transfer | Batch/half-hourly settlement; no minimum; available 24x7 since Dec 2019 |
| RTGS | Real Time Gross Settlement | Minimum Rs. 2 lakh; settles individually, real time; 24x7 since Dec 2020 |
| IMPS | Immediate Payment Service | Instant 24x7 transfers via mobile/MMID; no RTGS-style minimum |
| UPI | Unified Payments Interface (2016) | Instant app-to-app transfer using a VPA (name@bank); 24x7; BHIM app; QR payments |
Security tokens: IFSC (Indian Financial System Code) - 11 characters identifying the bank branch (e.g. SBIN0001234); MICR 9-digit cheque code; OTP (One Time Password) and 2FA (two-factor authentication: something you know + something you receive/are). Safety rules: banks NEVER ask for PIN/OTP/password; check https + padlock before paying; avoid public Wi-Fi for transactions; unknown links = phishing (see cyber-security topic).
Detailed notes
Banking from a distance
e-Banking (net banking) = banking through the bank's secured website; mobile banking = the same through an app. The ATM (Automated Teller Machine) works round the clock for cash withdrawal, balance enquiry, mini statement and PIN change. All of them sit on the same idea: instructions travel over secure networks instead of paper slips at a counter.
The money-transfer rails of India
| Rail | Full form | Style |
|---|---|---|
| NEFT | National Electronic Funds Transfer | moves in batches (half-hourly slots); no minimum; 24x7 since 2019 |
| RTGS | Real Time Gross Settlement | real-time, transaction by transaction; minimum 2,00,000 rupees |
| IMPS | Immediate Payment Service | instant, runs inside mobile/internet banking, 24x7 |
| UPI | Unified Payments Interface | instant app-to-app transfer by UPI ID or QR (PhonePe, GPay, Paytm); built by NPCI (National Payments Corporation of India) |
RTGS's rule is asked again and again: minimum 2 lakh rupees — NEFT has no minimum.
The codes on a cheque and beyond
| Code | Size | Job |
|---|---|---|
| IFSC (Indian Financial System Code) | 11 characters | identifies the exact bank branch for NEFT/RTGS/IMPS (e.g. SBIN0001234: 4 letters bank, 0, 6 characters branch) |
| MICR (Magnetic Ink Character Recognition) | 9 digits | the cheque number strip at the bottom; speeds cheque clearing |
| SWIFT | — | the code system for international wire transfers |
Safety: OTP, PIN, CVV and two factors
- PIN = Personal Identification Number (your secret at ATM/UPI); CVV = the 3-digit Card Verification Value printed on the card's back; OTP = One Time Password, valid for one login/transaction only.
- Two-factor authentication (2FA) = password plus something else (OTP or fingerprint) — two locks instead of one.
- Real banks never ask for PIN, OTP, CVV or passwords by phone, SMS or mail — any such caller is a fraudster. Report cyber-fraud on the national helpline 1930; IFSC-like codes should never be typed on a link received from a stranger.
Quick revision
- NEFT = batches, no minimum; RTGS = real-time, minimum 2 lakh; IMPS/UPI = instant, 24x7; UPI by NPCI.
- IFSC = 11 characters (branch identity); MICR = 9 digits (cheque strip); SWIFT = international.
- OTP = one-time password; CVV = 3 digits on card back; 2FA = password + OTP/biometric.
- Banks never ask for OTP/PIN/CVV; cyber-fraud helpline = 1930.
Types of questions asked
Every way this subtopic shows up in exams — how to recognise it, the formula or logic to use, and a solved example.
Type 1: NEFT / RTGS / IMPS / UPI comparisonvery common5 practice Q
'Which rail has a minimum of 2 lakh', 'which is instant 24x7 by UPI ID', 'full form of NEFT/RTGS/UPI' — the rails' styles mixed in options.
- NEFT = batches, half-hourly slots, NO minimum.
- RTGS = real-time gross settlement, minimum 2,00,000 rupees.
- IMPS = instant inside banking apps, 24x7.
- UPI = instant app-to-app by UPI ID or QR, built by NPCI.
- The recurring trap: giving NEFT the 2-lakh minimum (it belongs to RTGS).
Example: A customer must transfer 25,00,000 rupees immediately, transaction by transaction. The suitable system is:
RTGS — real-time, transaction-wise, built for high-value transfers (minimum 2 lakh).
Type 2: OTP, PIN, CVV and 2FA safetyvery common5 practice Q
'Full form of OTP/CVV', 'a caller from the bank asks your OTP — what do you do', or which combination makes an e-transaction two-factor.
- OTP = One Time Password — one transaction, one use, short life.
- CVV = Card Verification Value — the 3-digit number on the card's back.
- PIN = Personal Identification Number.
- 2FA = password PLUS OTP/biometric — two independent locks.
- Banks NEVER ask for OTP/PIN/CVV by call, SMS or mail — the asker is a fraudster.
Example: A caller says he is from your bank and asks for the OTP that just arrived. You should:
Refuse and disconnect — real banks never ask for OTPs; this is a vishing fraud attempt.
Type 3: IFSC, MICR and SWIFT codescommon4 practice Q
'IFSC has how many characters', 'which code is used for international transfer', 'the 9-digit code on a cheque is'.
- IFSC = Indian Financial System Code, 11 characters — 4 letters (bank) + 0 + 6 (branch); used in NEFT/RTGS/IMPS.
- MICR = 9 digits, the magnetic-ink strip at the cheque's bottom.
- SWIFT = the code system for INTERNATIONAL transfers.
Example: The number of characters in an IFSC code is:
11 — e.g. SBIN0001234: SBIN (State Bank of India) + 0 + 001234 (branch).
Type 4: ATM and net-banking basicscommon3 practice Q
'ATM stands for', 'which of these can be done at an ATM', 'mobile banking vs net banking' — service identification.
- ATM = Automated Teller Machine — cash, balance, mini statement, PIN change, 24x7.
- Net banking = bank's website; mobile banking = bank's app.
- ATM transactions need the card + PIN; the PIN is never written on the card.
Example: The full form of ATM is:
Automated Teller Machine — the 24x7 machine for cash withdrawal, balance enquiry and mini statements.
Shortcut tricks
⚡ NEFT vs RTGS
RTGS = Really To Go, in batches of one, 2 lakh+ (real-time, gross = one-by-one, big amounts). NEFT = Nice Easy Batches (settlement in half-hourly batches, any amount).
Example: Minimum amount for RTGS?
Rs. 2 lakh.
⚡ IFSC 11
IFSC = 11 characters (4 bank code + 0 + 6 branch code), used on NEFT/RTGS/UPI branch routing. MICR is the 9-digit cheque strip.
Example: How many characters does an IFSC code have?
⚡ 2FA two keys
Two-factor = password (know) + OTP/biometric (have/are). One stolen password is not enough - that is the whole point.
Example: Entering a password followed by an SMS OTP is an example of?
Two-factor authentication.
Where students lose marks
Giving NEFT the 2-lakh minimum - RTGS has it; NEFT has no minimum.
Saying IMPS is only for banks abroad - IMPS is an Indian instant retail rail.
Sharing OTPs on calls 'from the bank' - real banks never ask; that is vishing.
