In this system when card is brought near to the RFID module, it reads the card information and it compares with the existing data in the memory and displays amount balance and controls the electrical load for certain time if it has sufficient balance. If it has insufficient balance then electrical load does not get on.
In this project, we are using Arduino Atmega328 microcontroller to process data. The 16×2 LCD displays status information of the circuit. The electrical ac load is interfaced with relay.
