Coin based mobile charging system provides an alternate solution to all mobile users for charging their mobile phones during travelling or in an emergency situation where they may not have conventional power banks. This system can also be implemented in commercial complexes and colleges where mobiles are not allowed. This system is based on Arduino UNO microcontroller which controls the entire system including provision of password based security for the mobile phones, once inserted in the slots. The paper also focuses on various applications of this system and how this system can be integrated so as to add more features, sustainability and reliability in it and solve the major problems faced by people related to charging their phones. The future scope of the system also revolves around implementing this system in rural areas where there are constant power failures.
