In earlier days, there are so many electoral systems i.e, paper ballots, punch cards.In the existing, fingerprint voting system was implemented using Arduino UNO technology.In this the information is first registered with help of user id and password.This information is checked by the data server and voting is done according to the information.Now we are proposing fingerprint voting system using Arduino Mega256 technology.For Finger print scanning we are using R305 module as a scanner.This module has in-built ROM and RAM.This module can operate in 2 modes they are Master mode and User mode.We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id.When this module is interfaced to the MEGA256, we will be using it in User mode.When coming to our application, only authorized persons can be available for voting, thereby avoiding rigging.This scanner is interfaced to MEGA256 microcontroller.By using this controller we will be controlling the scanning process.After the scanning has been completed the person has to press a key among available switches, immediately one vote is credited and stored in the server.The wifi module is used for accessing the webpage.After the voting has been completed if he presses the switch again, the vote will not be considered.If an unauthorized person tries to scan his image then an indication will be given by a buzzer which is interfaced to the controller.This project uses regulated power supply of 5V.
