Paper-based methods
An alternative method that is still paper-based known as ballot letters is used in Israel, where polling booths contain a tray with ballots for each party running in the elections; the ballots are marked with the letter(s) assigned to that party. Voters are given an envelope into which they put the ballot of the party they wish to vote for, before placing the envelope in the ballot box. The same system is also implemented in Latvia. The system is used commonly in open lists or primary elections, where voters must choose a single party whose candidates they are allowed to choose between.
