### QR Code: The Frictionless Currency of Tomorrow *CDC English Curriculum Reading Text* In an increasingly digital global economy, money is undergoing a quiet but historic transformation. In marketplaces, department stores, supermarkets, and roadside tea stalls across Nepal and the world, the familiar monochrome square matrix known as the **Quick Response (QR) code** has emerged as the universal symbol of modern frictionless commerce. Originally invented in Japan in 1994 by Masahiro Hara of Denso Wave to track automobile parts through high-speed assembly lines, the QR code was designed to store over seven thousand numeric characters—hundreds of times more data than a traditional linear barcode. The technology was deliberately released to the public domain without patent royalties, laying the foundation for worldwide adoption. Today, QR payment architectures operate through two distinct operational models: 1. **Merchant-Presented Mode:** The merchant displays a printed static QR standee or generates a dynamic QR code on an optical POS terminal. The consumer scans the code using a smartphone camera or mobile banking wallet (such as eSewa, Khalti, or Fonepay), verifies the merchant credentials, and authorizes payment. 2. **Customer-Presented Mode:** The consumer generates a unique, short-lived QR code on their smartphone screen, which the retail cashier scans using an optical scanner. To prevent fraud and ensure that any banking application can interact with any merchant standee, international payment consortia such as **EMVCo** (founded by Europay, Mastercard, and Visa) have standardized QR payment specifications. In Nepal, the introduction of the unified **NepalQR** standard by Nepal Rastra Bank has accelerated this transition, enabling small farmers, taxi drivers, and neighborhood grocers to accept instant digital payments without investing in expensive electronic card-swiping hardware.

Common Exam Pitfalls to Avoid

✓ Correct Approach: "Can you tell me where he lives?"

Why: Indirect questions require standard declarative word order (Subject + Verb) after the introductory connective.
