Could this ever be done in something like a General Election?

When I vote, its just me and the ballot box, but online, can my vote really be anonymous?

Bad news. Ballot papers are numbered and they write down that number next to your name.

“Today, to prevent fraud, every ballot paper carries a Serial number as well as a unique official mark. This means that, although the ballot in UK elections is supposed to be secret, it is theoretically possible to trace each vote to the voter who cast it. It is, however, illegal to do so.”


The advantage of it being on paper is that it will be labour intensive and more difficult to conceal if you tried to trace who voted what.
