Scale is a bit of an issue.

We need results in as short a time as possible, ws have about 100 crore registered voters, of whom about 70% on average vote, meaning that the ECI must process 70 Crore votes, in under 10 hours.

Making that happen in a free and fair way is a logistical challenge, one that we undertake every 5 years.

One more large advantage of EVMs is making booth capture very expensive (because EVMs have a inbuilt rate limit, but a ballot box does not).

At any rate, with VVPAT being there, it adds another layer of security.

For everyone wondering: 100 crore is 1 billion, 70 crore is 700 million.

Why do you need the result in under 10 hours?
