Digital Payments — Set 1

Correct Answer: B. Unified Payments Interface

• **Unified Payments Interface (UPI)** = a real-time inter-bank payment system developed by NPCI that allows instant 24×7 fund transfers using a Virtual Payment Address (VPA), without sharing bank account details. • **April 2016 launch** — UPI was launched by NPCI in April 2016, built on top of IMPS infrastructure; first live transaction on August 25, 2016; now processes 10+ billion transactions/month. • UPI allows linking multiple bank accounts in a single app; standard transaction limit is ₹1 lakh per transaction (₹2 lakh for specific categories like healthcare, education, IPO). • 💡 Unique Payment Interface is wrong — 'Unique' is not part of the expansion; Universal Payment Index is wrong — UPI is not an index; United Payment Interface is wrong — 'United' is not the word, it is 'Unified' meaning combined/integrated.

Correct Answer: D. National Payments Corporation of India (NPCI)

• **National Payments Corporation of India (NPCI)** = a not-for-profit company incorporated in December 2008 under the Companies Act as a Section 8 company, promoted by RBI and the Indian Banks' Association (IBA) under the Payment and Settlement Systems Act, 2007. • **Retail payments umbrella** — NPCI operates UPI, IMPS, RuPay, NACH, FASTag/NETC, AePS, BHIM, Bharat QR, and BBPS — covering virtually all retail digital payment systems in India. • NPCI is not a regulator; RBI is the regulator, while NPCI is the infrastructure operator that builds and runs the payment rails. • 💡 SEBI is wrong — SEBI regulates securities markets, not payment systems; RBI is wrong — RBI is the regulator/supervisor of payments policy, not the operating umbrella entity; NITI Aayog is wrong — it is a policy think tank with no payment operating role.

Correct Answer: B. Rs. 1,00,000

• **Rs. 1,00,000 (₹1 lakh)** = the standard single-transaction limit on the BHIM UPI app, consistent with the general UPI per-transaction cap set by NPCI. • **Daily limit also ₹1 lakh** — the total daily transaction limit on BHIM is also ₹1 lakh; however, certain special categories (healthcare, education, IPO subscriptions) allow up to ₹2 lakh per transaction on UPI. • BHIM was launched by NPCI in December 2016 and is a government-backed UPI app named after B.R. Ambedkar; it supports multiple bank accounts and USSD (*99#) as fallback. • 💡 Rs. 50,000 is wrong — that is below the actual ₹1 lakh limit; Rs. 20,000 is wrong — far too low; Rs. 2,00,000 is wrong — ₹2 lakh applies only to specific UPI categories, not the general BHIM limit.

Correct Answer: D. Quick Response (QR) Code

• **Quick Response (QR) Code** = BharatQR is an interoperable QR code-based payment solution jointly developed by NPCI, Mastercard, and Visa, allowing merchants to accept payments via a single QR code across multiple networks. • **Interoperability** — BharatQR works with RuPay, Visa, and Mastercard cards as well as UPI; merchants do not need separate QR codes for each network, reducing costs. • Launched in February 2017, BharatQR was among the world's first interoperable QR-code-based payment acceptance solutions. • 💡 BLE is wrong — Bluetooth Low Energy is used for proximity-based IoT communication, not standard merchant QR payments; RFID is wrong — RFID is used for FASTag/NFC cards, not QR merchant payments; NFC is wrong — NFC is used for contactless tap-and-pay cards, not QR code scanning.

Correct Answer: A. Aadhaar

• **Aadhaar** = AEPS stands for Aadhaar-enabled Payment System, a payment service operated by NPCI that uses Aadhaar biometric authentication (fingerprint or iris scan) to authorize financial transactions at Business Correspondent (BC) micro-ATM terminals. • **Services & limit** — AEPS allows cash withdrawal, cash deposit, balance enquiry, mini statement, and Aadhaar-to-Aadhaar fund transfer; daily cash withdrawal limit is ₹10,000. • AEPS does not require a debit card or smartphone — only the Aadhaar number and biometric, making it critical for last-mile banking in rural and semi-urban India. • 💡 Account is wrong — the 'A' is specifically for Aadhaar, not just any account; Authentication is wrong — authentication is the process used, not the system name; Authorized is wrong — it has no relevance to the acronym expansion.

Correct Answer: A. IMPS

• **IMPS (Immediate Payment Service)** = a 24×7, 365-days real-time inter-bank electronic fund transfer service launched by NPCI in November 2010, using mobile number + MMID or account number + IFSC. • **₹5 lakh limit** — IMPS has a per-transaction limit of ₹5 lakh; it works via mobile banking, internet banking, ATM, and bank branches at any hour including holidays. • IMPS is the underlying infrastructure on which UPI is built; UPI added a VPA layer and app-based experience on top of IMPS rails. • 💡 RTGS is wrong — RTGS is real-time but has a minimum ₹2 lakh threshold and was not 24×7 until December 2020; NEFT is wrong — NEFT processes in half-hourly batches (not instant) and became 24×7 only in December 2019; CTS is wrong — CTS (Cheque Truncation System) is for electronic cheque clearing, not fund transfers.

Correct Answer: D. Unstructured Supplementary Service Data

• **Unstructured Supplementary Service Data (USSD)** = a session-based communication protocol built into GSM networks that allows feature phone users to access mobile banking by dialing *99# — no internet, no smartphone, no data plan needed. • **Launched under NUUP** — the *99# service (National Unified USSD Platform) was launched by DoT and NPCI in 2012; it supports 12 Indian languages and works on any GSM handset across all telecom operators. • USSD sessions are real-time and interactive (menu-driven) but limited to 182 characters per screen; they are especially useful for rural financial inclusion. • 💡 Unique Standard Service Data is wrong — 'Unique' and 'Standard' are not part of the expansion; Unified Supplementary Service Data is wrong — 'Unified' replaces 'Unstructured', which changes the meaning; Universal System Service Data is wrong — all three words are incorrect substitutes.

Correct Answer: C. NPCI

• **NPCI** = the National Electronic Toll Collection (NETC) program is managed by NPCI, which provides the interoperable framework for FASTag-based toll payments at highways across India. • **FASTag & RFID** — FASTag uses RFID (Radio Frequency Identification) technology; the tag is affixed on the vehicle windscreen and automatically deducts toll from the linked bank account or prepaid wallet when the vehicle passes through a toll plaza. • FASTag became mandatory for all four-wheelers from February 15, 2021; NHAI manages the physical highway infrastructure, but NPCI manages the payment settlement backbone. • 💡 RBI is wrong — RBI is the payment regulator, not the NETC operator; Ministry of Finance is wrong — it has no direct operational role in toll payment systems; NHAI is wrong — NHAI manages highways and toll infrastructure, not the electronic payment settlement network.

Correct Answer: A. Virtual Payment Address

• **Virtual Payment Address (VPA)** = a unique alphanumeric identifier (e.g., name@bank) used in UPI to send or receive money without sharing sensitive bank details like account number or IFSC code. • **Format & registration** — a VPA is created by the user in a UPI-enabled app and maps to the underlying bank account; it can be set as any preferred handle (e.g., 9876543210@upi, manmeet@sbi); one person can have multiple VPAs. • VPA eliminates the need to remember or share account numbers; it is the key innovation that made UPI simpler than IMPS (which required MMID + mobile number). • 💡 Verified Payment Address is wrong — 'Verified' is not the word; the address is 'Virtual' (not physical); Virtual Payment Account is wrong — it is an Address, not an Account; Validated Payment Address is wrong — 'Validated' changes the meaning entirely.

Correct Answer: B. 2008

• **2008** = NPCI was incorporated in December 2008 as a Section 8 (not-for-profit) company under the Companies Act, promoted by RBI and the Indian Banks' Association (IBA) under the Payment and Settlement Systems Act, 2007. • **Operational timeline** — though incorporated in 2008, NPCI became fully operational by 2009–10; its first major product was NFS (National Financial Switch for ATM interoperability); IMPS launched in 2010, RuPay in 2012, UPI in 2016. • NPCI has ten core promoter banks including SBI, PNB, Canara Bank, Bank of Baroda, HDFC, ICICI, Citibank, and others. • 💡 2010 is wrong — that is the year IMPS was launched, not when NPCI was incorporated; 2014 is wrong — by 2014 NPCI was already running multiple products including RuPay; 2005 is wrong — NPCI did not exist in 2005; the Payment and Settlement Systems Act itself came in 2007.
