In order to safeguard the ballot, in most countries single integrated ballot papers bear an official stamp and/or the signature of an authorised polling official. According to the Code of Good Practice in Electoral Matters, the signing and stamping of ballot papers, however, should not take place at the point in which the ballot is presented to the voter because, theoretically, the stamp or signature might mark the ballot in such a way that the voter could be identified later during the count (CDL-AD(2002)023rev2-cor, Expl. Report para 34).
