Organisation Profile
- →Founded: December 2008
- →Type: Not-for-profit organisation
- →Promoted by: RBI + Indian Banks' Association (IBA)
- →10 core promoter banks: SBI, PNB, Canara Bank, Bank of Baroda, Union Bank, Bank of India, ICICI Bank, HDFC Bank, Citibank, HSBC
- →Goal: Simple, safe, fast, affordable payment services for all Indians — 'less-cash society'
NPCI Products Portfolio
⚠️ Exam note — NPCI founding
NPCI was founded in December 2008 (not 2005 when BPSS was set up, and not 2009 when NFS was handed over). The Board for Payment and Settlement Systems (BPSS) was set up in 2005 — it released a vision document that led to NPCI's formation.
National Financial Switch (NFS)
- →Largest network of shared ATMs in India
- →Developed & deployed by IDRBT in 2004
- →Transferred to NPCI on 14 December 2009
- →As of January 2022: 1,203 members; 2.55 lakh+ ATMs
- →Strong sustainable operational model; comparable to global ATM networks
Basic Services
Value-Added Services (on ATMs/CDMs)
💡 Key point
All NFS value-added services can be used at any other member bank's ATM — that's the whole point of the interoperability switch.
NACH & IMPS — Bulk Clearing and Instant Payments
FreeNational Automated Clearing House (NACH)
NACH is a web-based solution for high-volume, interbank, repetitive and periodic electronic transactions. It consolidated India's multiple ECS systems into one standardised platform.
Use Cases
- →Collection of telephone, electricity, water bills
- →Loan repayments (EMIs)
- →Investments in mutual funds
- →Insurance premium collections
- →Salary / dividend / interest payouts
Aadhaar Payment Bridge (APB) System
- →Developed by NPCI to channel Government subsidies and benefits
- →Links Government Departments + sponsor banks (one side) to beneficiary banks + beneficiaries (other side)
- →Made Direct Benefit Transfer (DBT) scheme a success
- →Supports Aadhaar-based transactions for Financial Inclusion
⚠️ Exam trap
NACH is not for single high-value transactions (that's RTGS). NACH is for bulk, repetitive transactions. It replaced multiple ECS systems by harmonising standards and removing local barriers.
IMPS — Immediate Payment Service
IMPS is an instant, 24×7, interbank electronic fund transfer system. It is managed by NPCI and built on the NFS network. The framework is governed by the Payment and Settlement System Act 2007.
Channels Available
Salient Features
- →Instantly transfers funds across member banks
- →Available 24×7 including bank holidays
- →Safe, secure, easily accessible, cost-effective
- →Channel independent — not limited to mobile
- →Both sender and receiver get SMS confirmation on success
- →666+ members live (banks + PPIs)
Authentication by Channel
💡 Key IMPS point
Transfer is possible using beneficiary's mobile number + MMID, OR using account number + IFSC code, OR using Aadhaar number. Mobile banking registration is NOT mandatory for ATM/internet channels.
⚠️ Exam trap — IMPS vs mobile-only
A common wrong answer: "IMPS can be used only through mobile phones." This is FALSE — IMPS works via mobile, internet, ATM, SMS, branch, and USSD. The correct answer to "which is NOT true about IMPS" in MCQ = option (a) "IMPS allows electronic fund transfer only through mobile phones."
UPI & BHIM — Unified Payments Interface & BHIM App
Unified Payments Interface (UPI)
UPI powers multiple bank accounts into a single mobile application — seamlessly combining banking features, fund routing, and merchant payments. It supports both Push (Pay) and Pull (Collect) transactions.
Core Features
- →24×7 × 365 days — round the clock
- →Single Click, two-factor authentication
- →Virtual address (VPA) — no card/account/IFSC needed
- →Upper limit: ₹2,00,000 per transaction
- →Pay utilities, merchant payments, Scan & Pay (QR)
- →Raise complaints from mobile app directly
Transaction Types
| Type | Description |
|---|---|
| Pay Request (Push) | Customer pushes funds to beneficiary using VPA, Mobile+MMID, or A/c+IFSC |
| Collect Request (Pull) | Customer pulls funds from remitter using Virtual ID — unique advantage over IMPS |
| Non-Financial | Generate OTP, Mobile Banking Registration, Set/Change PIN, Raise Dispute, Check TX Status |
Transfer Channels
🧠 UPI Pull (Collect) Process — Steps
- 1.Log in to bank's UPI app
- 2.Select 'Collect Money' (request for payment)
- 3.Enter remitter's Virtual ID, amount, account to credit
- 4.Review confirmation screen (name associated with Virtual ID shown)
- 5.Payer receives notification on mobile
- 6.Payer opens UPI app, reviews request → accepts or declines
- 7.Payer enters UPI PIN to authorize
- 8.Both parties get successful/declined notification + SMS from bank
UPI 2.0 — 4 New Features
Feature 1: One-Time Mandate with Block Functionality
Consumer pre-authorises a transaction and blocks funds in account for future debit. Mandate is digitally signed and stored at customer's account-holding bank AND PSP bank. Both validate digital signature at time of debit.
Feature 2: Overdraft (OD) Account as Underlying Account
Earlier only Savings and Current accounts could be linked. Now OD accounts can also be linked (if bank grants OD eligibility). Balance check returns two values: available balance and actual/usable balance.
Feature 3: Invoice in the Inbox (View Attachment & Pay)
Merchants can share invoices with customers before payment via secure link in collect/intent message. Customer verifies invoice before authorizing. Initially only for verified merchants.
Feature 4: Signed Intent & QR
Additional security layer when paying via intent or scanning QR. Signed QR reduces tampering of QR codes and prevents non-verified entities from intercepting payments.
UPI vs IMPS — Key Differences
| Feature | UPI | IMPS |
|---|---|---|
| Pull (Collect) request | ✅ Yes — unique feature | ❌ No |
| Merchant Payments | ✅ Simplified via Virtual ID / QR | Limited |
| Single app for multiple banks | ✅ Yes | Per bank app |
| Authentication | Single Click 2FA (UPI PIN) | MPIN / ATM PIN / IBP |
| Channel | Mobile-first | Mobile, ATM, Internet, Branch, USSD, SMS |
| Amount limit | ₹2,00,000 | As per channel; bank prescribed limit |
| Sharing money with friends | ✅ Bill split, QR share via WhatsApp etc. | Not built-in |

⚠️ MCQ answer tip
QR Code = (a) black squares + (b) square grid + (c) white background + (d) contains item information → The correct MCQ answer is (e) All of the above.
