It was a concern that given the systemic and design flaws and lack of process checks, it is impossible for us to ensure a fool-proof election with current design.
But VVPAT only tells us what is going in to the VVPAT. What is going to the Control Unit is still unknown to the voter.
But now with VVPAT, the EVM as a black box knows who are the candidates, which serial number they are at etc.
Again dangerous!
