Abstract: In this project, a coin based secured cell phone charger with RFID is designed for public people use. Cell phone charger is also provided with RFID for mobile security. Many times the mobile battery becomes low down or lifeless in the middle of the talk. When right to use to standard phone charger and availability of grid power supply is not convenient, in such cases this coin based secured cell phone charger with RFID is very much useful. The coin based secured cell phone charger works in accordance with programming written in the “PIC Câ€. When a coin is inserted, the microcontroller will detect the input. The controller reads the program written in „c‟. The tray placed to facilitate the charging of the mobile is opened which contains RFID card for mobile security and multi pin charger. Mobile is placed in the tray and the tray is closed within the time that is written in the code. Meanwhile relay switches multi pin charger. The time period depends on the coding written in the controller. With the help of multi pin charger we can charge different mobiles. And by providing two or more trays it is possible to charge more than one mobile at a time. After the time of charging is completed the customer can punch RFID card to the RFID reader and can withdraw the mobile from the tray.
