Abstract

Development of Coin Payment System and RFID Access for Phone Charging Station is a project that can help peoples at the restaurant, recreational park or shopping malls that urgently need a back-up power to charge their smartphone in the absence of power bank and lack of switch socket outlet. The aim of this project is to implement Radio-Frequency Identification (RFID) for security lock and to apply the paidsystem to Phone Charging Station. This project use coin acceptor to receive and detect valid coin insert by user. Then RFID reader will interfaced with solenoid lock for locking mechanism. The Arduino programming will be use to program the value of coins equivalent with time of charging to user alongside other input and output used. After that, the program will be upload to Arduino microcontroller. Liquid Crystal Display (LCD) will shows amount of coins inserted by user and the value keep incrementing as long as user insert amount of coin they desired. The solenoid lock state depend on RFID reader that will allow the access only when tag detected by reader is valid. Relay will switch on and allow the flow of power supply to phone soon after the infrared sensor detect the closure of door and locked by solenoid. When the time charging countdown finish, relay will turn off the power supply to phone. The technology of RFID system will make it more secure and fast-access to user if Phone Charging Station are located at public places. The paid system using coin are able to implemented to Phone Charging Station as a power supply exchange with currency that can be profitable to its owner
