Voting is done in one of two ways: manually marking a ballot paper with a red pencil or electronically, using a voting machine. In 2005, almost all municipalities planned to abandon pencil-and-paper voting. However, serious doubts were raised over the inviolability of the computers used from potential vote tampering and electronic eavesdropping. This led to a run on foreign voting machines and reintroduction of the red pencil in some municipalities in 2006, occasionally using converted medical waste disposal containers as voting boxes.
