Comment :  The main drawbacks of current VVPAT solutions are:
· VVPAT solutions allow voters to verify that votes are cast as they intended but
do not provide sufficient assurance that the votes will be counted as they were
cast. Paper records, once verified by voters, are actually vulnerable to a
number of attacks, including (i) the addition of bogus votes (also known as “ballot stuffing”), (ii) the elimination of valid votes, and/or (iii) the alteration of
valid votes.
· VVPAT solutions do not provide election authorities with accurate mechanisms
to determine the correct result in case of discrepancies between the results
provided by the count of electronic votes in the DRE and the count of paper
votes.
· VVPAT solutions are based on printed paper ballots and, therefore, they are not
accessible for blind or visually impaired voters.
