"I'm from Brazil, and here is actually quite organized. It's mandatory to vote here, if you don't you can "justify" (as we say), which means going to the registration center after the election and saying you didn't vote. If you don't vote nor justify you can pay a small fine and are not elegible for public jobs or to issue a passport until you do one of those two things.As it's mandatory, it's always on a sunday, and the poles are open from 8am to 7pm, normally in schools, but not only. We have a electronic ballot (I uploaded a pic) where we put the number of the candidate we want to vote, and we only vote for the politians, we don't vote for laws or any of these. And is the one with the majority of the total votes that win, we don't have the delegates system as you have in the USA. Normally the results are in before 10pm of the same day.We all have a voting document ("electoral title"), which has our electorate number, the number of our zone (which indicates the school) and the number of our session, which indicates the room we have to go. Normally it's the same place every election, and if you change your address you can go to the registration center and change the place you vote. In the room there is only one booth that look similar to yours in the USA,  we also have to sign a book, and present our ID. While someone is voting it's not allowed for other people to be too close to the booth and peek on the vote. Normally it doesn't take very long to vote."
