The rapid growth of digital technology has transformed traditional recharge systems into smart, AI-powered digital platforms. Mobile recharge, DTH recharge, electricity bill payment, FASTag recharge, and online wallet top-ups are now integrated into unified digital ecosystems. This research paper explores the development of an AI-based smart recharge system that enhances security, personalization, fraud detection, and user experience. The study highlights the role of Artificial Intelligence (AI), Machine Learning (ML), blockchain security, and digital payment platforms such as Paytm, PhonePe, and Google Pay in revolutionizing recharge services. The paper concludes that AI-driven recharge platforms provide faster transactions, predictive recharge reminders, fraud prevention, and financial inclusion.
