for European, regional and municipal elections, voters who will be absent from their town on election day or are ill or disabled, may request a postal vote at a post office. The application must be submitted personally or through a representative in case of illness or disability certified by a medical certificate. Switzerland Swiss federal law allows postal voting in all federal elections and referendums, and all cantons also allow it for cantonal ballot issues. All voters receive their personal ballot by mail and may either cast it at a polling station or mail it back. As of 2019, approximately 90% of Swiss voters cast ballots using Remote Postal Voting. In Switzerland, starting in 2004, 15 cantons conducted electronic voting pilot programs. In three cantons, Swiss voters resident abroad voted electronically; Geneva Canton, Canton of Neuchâtel, and Basel-Stadt. The programs were closed in June and July 2019, and the plan is for new designs to be available by 2023. In 2019 the Swiss government invited researchers to test the security of online voting, and in early March 2019 researchers found back doors which let insiders, and hackers who accessed management systems, change results without detection. Thailand Absentee balloting started in Thailand first time in the 2000 general election. It is promulgated according to a provision in the 1997 constitution. The absentee ballot can be cast within Thailand and in foreign countries, where Thailand has diplomatic missions. Voters can cast the absentee ballot in 2 cases: (1) those who have their household registration in their constituency but will not be at their constituency on the election day, and wish to cast their vote in advance; and (2) those who physically reside in other locations out of their constituency at least 90 days prior to the election day, and will not be able to travel back to their constituency on the election day. In both cases, voters wishing to cast their absentee ballot must register with the election committee 30 days in advance prior to the general election date. Voters within Thailand can cast their vote either at the designated district offices for absentee voting in their provinces or through mail. Likewise, voters overseas can register to vote with the Thai missions in their country of residence or send the ballot to them by mail. The absentee voting date is normally designated a week ahead of the general election date. United Kingdom
