Fingerprint Based Voting System

We are all familiar with the current electronic voting machines where the user has to press the voting button. But the machines were criticized from the start. This article explains how to build a biometric based voting machine using a fingerprint sensor R307 and Arduino Uno. In this system, a person has to register their fingerprints matchings to the system database which will be stored centrally in Arduino. Voters must put their finger on the fingerprint sensor, and if the finger matches the previously stored information, the voter can vote. To determine the voters, the ID of the candidate will be initiliazed to store fingerprint so that the voter votes. It has simple equipment and is easy to access. It shortens the voting time, is easy to move from ballot boxes to ballot boxes, reduces the number of personnel in the ballot boxes, provides smooth, easy and accurate counting
