"Several countries are already using, or are preparing to introduce mechanical and electronic voting methods. The advantage of these methods becomes apparent when a number of elections are taking place at the same time, even though certain precautions are needed to minimise the risk of fraud, for example by enabling the voter to check his or her vote immediately after casting it. Clearly, with this kind of voting, it is important to ensure that ballot papers are designed in such a way as to avoid confusion. In order to facilitate verification and a recount of votes in the event of an appeal, it may also be provided that a machine could print votes onto ballot papers; these would be placed in a sealed container where they cannot be viewed. Whatever means used should ensure the confidentiality of voting. "
