In a world where Europeans still fumble for coins at cafes, India’s digital payments culture stunned her. “I never expected to pay for street food, rickshaws, even tiny shops; all with my phone,” she said. What’s wild? UPI isn’t just for cities or malls. It’s woven into everyday life; from chaiwallahs to auto drivers. Launched in 2016, UPI transactions jumped from 1.78 crore to 24,162 crore in 9 years. That’s not just tech; it’s a quiet revolution. While the world talks about cashless societies, India’s already living it; one QR code at a time.
