Quote
"Registered voters may be provided with voter cards as proof of their registration. There may be legal provisions that allow non-registered eligible voters to be included on special supplementary voter lists on election day. In all cases, the procedures in place should ensure that all eligible electors are able to vote, only eligible electors are able to vote and that adequate measures are taken to prevent multiple registration that could lead to multiple voting (e.g., through changes in residence or name changes after marriage). Procedures should also be in place to ensure the removal of the names of deceased persons and the inclusion of newly eligible voters."
