Various governments require a certification of voting machines.
In the United States there is only a voluntary federal certification for voting machines and each state has ultimate jurisdiction over certification, though most states currently require national certification for the voting systems.
Germany In Germany the Physikalisch-Technische Bundesanstalt was responsible for certification of the voting machines for federal and European elections till 2009. Since the respective law, the Bundeswahlgeräteverordnung ("Federal Voting Machine Ordinance") is considered to be in contradiction to Germany's Constitution, this responsibility is suspended. The only machines certified so far are the Nedap ESD1 and ESD2.
