Read the passage carefully and answer the questions that follow. India's digital transformation over the last decade has been revolutionary, evolving into one of the largest digital ecosystems globally. Spearheaded by government initiatives, the country has seen an unprecedented surge in internet penetration and digital payments. A pivotal element in this journey has been the Unified Payments Interface (UPI), which has transformed the country's payment landscape by facilitating real-time, low-cost transactions. The growth is staggering; by FY25, UPI accounted for approximately 81% of all retail digital payment transactions. This rapid adoption was further accelerated by the pandemic, which made digital alternatives for commerce, education, and work essential. However, this digital journey is not without its obstacles. A significant digital divide persists between urban and rural populations, with many villages still struggling with basic connectivity and digital literacy. Furthermore, the rapid growth has exposed vulnerabilities to cybersecurity threats, including data breaches and identity theft, raising concerns about the adequacy of existing data protection mechanisms. While the rise of UPI is a success story, some analysts express concern that its dominance might stifle innovation in other payment modes, such as credit cards, thereby limiting consumer choice. Addressing these challenges—bridging the digital divide, bolstering cybersecurity, and fostering a competitive payments market—will be crucial for India to fully harness the potential of its digital economy.
