Money & Economy: NEB Class 12 English Guide
Understand QR-code payment models, scheme operators and security, then master abbreviations, /ʊ/ and /uː/, question forms and digital-payment news writing.
Reading overview
Read “QR Code” as a payment-system explanation
The prescribed text traces the development of Quick Response codes from wider data use into retail payments. QR standards enabled machines and phones to read encoded information quickly. Payment companies and mobile platforms then used the code as an entry point to a digital transaction.
The code itself is not money. It carries data that helps an app identify a merchant, amount or payment instruction. Banks, wallets, networks and scheme operators complete the transaction.
Two payment models
Distinguish customer-presented and merchant-presented QR
| Model | Who displays the code? | Who scans? |
|---|---|---|
| Customer-presented | Customer’s phone shows a temporary payment code | Merchant device |
| Merchant-presented static | Merchant displays a fixed code | Customer phone; amount may be entered |
| Merchant-presented dynamic | Merchant generates transaction-specific code | Customer phone; amount may be prefilled |
Dynamic codes can reduce manual amount entry, but secure design and user verification remain necessary.
Transaction flow
Follow a merchant-presented payment step by step
- The merchant displays a registered QR code.
- The customer opens an authorised banking or wallet app.
- The app scans and decodes the merchant information.
- The customer checks merchant name and amount.
- The customer authenticates with PIN, password or another approved method.
- The payment network routes and authorises the transaction.
- Both sides receive confirmation and verify success.
A screenshot or spoken claim is not equal to confirmation inside the official system.
History and standards
Standards make codes more widely usable
QR technology developed prominently in East Asia, and its international standardisation supported wider device compatibility. Tencent and Alibaba helped normalise mobile QR payments in China through services such as WeChat Pay and Alipay. Later, EMVCo and global card networks developed payment specifications aimed at broader interoperability.
Standardisation does not guarantee that every wallet works with every merchant. Interoperability depends on network, rules, settlement and local regulation.
Scheme operator
A payment ecosystem needs rules and dispute handling
Acceptance
Defines branding and where the scheme can be used.
Rules
Sets technical and operational requirements.
Relationships
Coordinates issuers, acquirers, merchants and service providers.
Exceptions
Provides procedures for failure, refund and dispute.
Convenient scanning is only the visible front of a larger financial arrangement.
Security
Verify before authorising a QR payment
- Use the official bank or wallet application.
- Check that the displayed merchant name is correct.
- Confirm the amount and transaction purpose.
- Protect PIN, password and one-time codes.
- Reject codes pasted suspiciously over a genuine display.
- Wait for real-time in-app confirmation.
- Keep records and report an exception through official channels.
A QR code can be replaced or redirect data, so scanning alone does not establish trust.
Benefits and limits
Avoid calling QR payment a universal solution
| Potential benefit | Related limitation |
|---|---|
| Low-cost merchant acceptance | Needs smartphone, connectivity and account access |
| Fast contactless transaction | User error or fraud can still occur |
| Digital record | Privacy and data protection matter |
| Access for small merchants | Fees, literacy and support affect adoption |
| Less cash handling | Cash remains necessary during outages or exclusion |
Nepal economy
Digital payment can widen access when systems are inclusive
QR payments can help small shops accept digital transfers without expensive card terminals. They can improve transaction records and reduce some cash-handling friction. Nepal’s mobile connectivity and banking initiatives support this growth.
However, rural connectivity, device cost, digital literacy, accessibility, cybersecurity and grievance handling remain important. A resilient economy should improve digital options without abruptly excluding cash users.
Vocabulary
Learn financial words through their role
| Word | Meaning | Use |
|---|---|---|
| Prominent | Easily noticed or important | A prominent payment model |
| Vulnerable | Exposed to harm | Vulnerable to code replacement |
| Potentially | Possibly in the future | Potentially wider access |
| Transaction | Exchange such as buying or selling | Payment transaction |
| Initiative | New organised action | Financial-literacy initiative |
| Robust | Strong and dependable | Robust authentication |
Abbreviations
Expand the shortened forms accurately
- QR: Quick Response
- ISO: International Organization for Standardization
- IEC: International Electrotechnical Commission
- URL: Uniform Resource Locator
- EMVCo: the payment-technology standards body founded by major card companies
- PIN: Personal Identification Number
In formal writing, give the full form on first use and the abbreviation in parentheses.
Pronunciation
Contrast /ʊ/ and /uː/ by sound
The shorter /ʊ/ occurs in put, push, hood, full, bull, book, foot, look, hook, cook, should, soot and stood. The longer /uː/ occurs in boom, fool, food, loose, boost, groom, moon, soon, room and soothe.
Do not rely on spelling alone. Say each word, compare duration and check a learner’s dictionary audio model.
Grammar focus
Build different kinds of questions
| Type | Pattern | Example |
|---|---|---|
| Yes/no | auxiliary + subject + verb? | Do customers need an app? |
| Wh-question | wh-word + auxiliary + subject + verb? | How does the scheme handle disputes? |
| Subject question | who/what + verb? | Who operates the payment scheme? |
| Choice | question + or + alternative? | Does the customer or merchant display the code? |
| Indirect | opening + statement order | Could you explain how the code works? |
Do not use inversion inside an indirect question: write “Do you know where the bank is?” not “where is the bank?”
Writing focus
Write a news article on digital-payment growth
- Create a factual headline.
- Lead with the most important current development.
- Provide verified data, source and date.
- Explain drivers such as mobile access and merchant adoption.
- Include consumer benefit and security concern.
- Add attributed comment and future context.
Never invent statistics. Use Nepal Rastra Bank publications and name the reporting period.
Exam method
Answer mechanism, security and evaluation separately
- For “How can one pay?” give the ordered user steps.
- For the two models, identify who displays and who scans.
- For scheme operator, list rules, relationships and exceptions.
- For security, include merchant verification and confirmation.
- For “panacea,” weigh access and convenience against exclusion and risk.
- For grammar, identify whether who/what is subject before adding do/does.

Frequently asked questions
Money and Economy unit questions answered
It encodes information that helps an authorised app identify the merchant, amount or payment instruction; the network completes the transfer.
Either the customer presents a code for the merchant to scan, or the merchant presents a code for the customer to scan.
Use an official app, verify merchant and amount, protect authentication details and confirm success inside the payment system.
Revise yes/no, wh-, subject, choice, tag and indirect questions, including auxiliary use and statement order.
