Online Voting Vs Offline

Why don’t we have online voting system?Which country have Online voting system? so this is our today topic .In India most of youths are working far away from their home town ,they can not come down to their home town just for casting their votes. For example a person from Jharkhand can not travel from Chennai to Jharkhand just to cast his or her vote .It will cost money and time both . Second thing people needed to stand in queue to cast their votes. So if there will be Online voting system then every one can cast their votes easily . Now there are many people and politicians who are not supporting even EVM so how we can expect online voting. Estonia this country has been using online voting for quite sometime now(2009 onwards). The whole country is nearly 100% “Online”. From filling taxes to paying rent everything is online. They have good internet speeds and also they have made a robust system to vote online, as they claim. So question is why they are successful in  online voting system. See they created a better infrastructure for it .In India every one can not afford fast Internet system ,also many people are even not using internet .But question is we can create both type of voting system .
Those who are capable to cast their vote online they will vote online and those who are not able to vote online they will vote  offline. We are making online payment we are doing many things online so why can not we vote online. See biggest benefit of online voting system is , the youths and most of educated people who understand value of their vote and one who can recognise better political party and to individual members easily , are not able to cast their votes.This may looks not good to you but one day online voting will be common in India , only thing required is a better infrastructure.Till now I have only talked about good points of Online voting , now lets talk some negative points .Any one can pay to other for their vote , because both voter and the person who is paying to vote his party are in the same room . But in case of Offline voting ,even some one pays some ,still one can vote to other candidates because there is no proof that for which party that person has voted for. Second negative point about online voting is , you can not claim for which party you have voted, any software engineer can change the data easily . Still government can find some way to conduct online voting or government can create some way to vote even you are far away from your hometown.
