In rural areas, grid power is partially available in one day. Solar charging is a good way to overcome this. This technique can be used at train stations, bus stops, and markets. The basic design of this system is to provide users with uninterrupted communication if the user forgets to charge the battery or if the battery runs out. You can insert coins, Rs 1 coins, Rs 2 coins, Rs 5 coins and use the RFID reader to charge your mobile phone. Arduino NANO is used to detect the inserted coin and RFID with a laser and control the charging time for a certain period of time that the user can continue by inserting more coins. With the Arduino software installed on your computer, you can edit and upload programs to suit your application.

In this system, mobile charging is done using two methods. One is using RFID and the other is using the coins. For registered RFID users has to charge their mobile using RFID tag and for other users who has not registered they has to use coins like 1Rs, 2Rs, and 5Rs. RFID users will get locking system for their mobile for security purpose. Initially the door is opened so that user has to place their mobile inside it and scan the RFID tag if it is unregistered tag then it displays access denied please register on the LCD screen provided otherwise it displays access granted mobile charging. Here servo motor is using for opening and closing door, IR sensors are using to detect the coins and EM-18 RFID Reader module is using to read RFID tag.
This work aims to design a mobile charging system using coins and RFID. Today, the mobile industry is growing rapidly and technology is changing every year. There is a growing need for mobile phones for communication and bill payments. This system is used to charge in an emergency or when the batteries and are emptied without being connected to the mains. Urban people have enough grid power and alternatives to charge their cell phones, while rural people experience power outages and the cell phone's battery drains easily. This system works with both solar and grid power. This system works in two ways: insert a coin or register with an RFID tag. First, open the RFID tag to be registered. Users want to connect their phones and scan RFID tags. After registration, the door will close and the phone will start charging. Another possibility for an unregistered user to insert a coin and charge the mobile phone depends on the coin to be inserted, and the charging time of the mobile phone will be different.
