Electoral system and digital India

Now we are in the age of digital India then why the election procedure should not be digitalized too along with conventional electoral system. On the election day People come out in large number, stand in queues and wait for their turn to cast their vote. It takes a lot of time. All markets, business establishments, offices, schools, colleges are closed on this day which causes loss of business as well. When this system was adopted we didn't have advanced technology so we chose this system of electoral procedure. Now when every work is going to be performed online then why casting can't be performed online as well. It will save time of people and those who are not able to come to polling booth can vote from their homes. However, if someone wants to go to polling booth they can go to use their voting right in conventional way.
