Project on Biometric voting machine

This is a project I am presently working on, it is called biometric voting machine,. This is a machine which can be used to conduct elections, the machine is capable of accrediting voters before conducting of election, so the first process is the accrediting process, you have to be accredited before you can vote, so if u are not accredited when you come to vote the machine trigger an alarm to show that voice finger print is not stored in the machine. in the circuit diagram above, their is the finger print module. An add button delete button, increment and decreament buttons. Their is an led to display the election process. This machine is stress free it is going to be connected to the main inec server so as to see how the election is going on. And to your surprise you can not vote twice, when you want to vote for the second time it will trigger an alarm to show that you have voted before. So I am looking forward for your ideas, contribution, and more sore your upvote and resteem so as the world should know what a student in nigeria is trying to achieve thank you so much for your time and remain blessed
