Its always been a pencil. I've also scrutineered. No one gets to see the votes until everyone is standing around. Our system is better than the electronic voting system in the US which can't be audited. I trust cranky grey haired people far more than a computer and I work in the IT industry.
what other legal document can you/me use a pencil on?
what other legal document are you/me encouraged to use a pencil on? after all...who supplies the pencil.....?
