Abstract: In today's rapidly advancing technological landscape, the   ubiquitous presence of mobile devices has become a defining characteristic of modern society. From smartphones to tablets, laptops to wearable gadgets, these devices have seamlessly integrated into both personal and professional spheres, driving the need for efficient and accessible charging solutions. Traditional reliance on fixed charging stations or wall outlets often proves inconvenient, particularly in public spaces, outdoor events, or during travel where access to power sources may be limited. Moreover, the rise of smart technologies and cashless transactions has spurred the exploration of innovative charging solutions that cater to evolving preferences and requirements.

In response to these challenges, the Coin and Smart Card-Based Mobile Charging System emerges as a pioneering endeavor ,leveraging microcontroller technology, sensor systems, and RFID authentication to revolutionize the way electronic devices are powered. This abstract provides a comprehensive overview of the system's objectives, significance, and anticipated contributions to the realm of mobile charging technology.
