Certification of voting machines
Open-knowledge reference entry

Various governments require a certification of voting machines.

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.
