This is wrong. And I have read this argument so many times. This needs to stop.
1. First, a "white vote" is just an empty ballot
Nothing prevents the card being printed later, and used as if you voted in the first place.
2. there's no way to void your ballot.
You are supposed to write "void" in the card, but nothing prevents the authorities from reading from the chip, or worst writing down "void" to your non-void ballot.
3. The chip can hold multiple votes
Which the software will count, but will raise no warning whatsoever.
Also, in the case of a difference between the chip counter and the paper count, which one should be trust?
Should we throw away the entire table? if so, then a simple vote could then nullify the entire table
1. It's the same for traditional ballots, "Fiscales" and the table president prevent it. They go one ballot at a time checking if the vote has to be voided for failing with the protocol and adding the votes. Now they just have an automatic medium to double check the count. Each party has an incentive to find anything to void the oposition's votes.
2. Yes there is. This last election a friend of mine got his ballot voided because he didn't fold it while putting it in the box, which would reveal the ballot ("voto cantado").
3. Again, counters go one ballot at a time if one turns double it's voided.
