Identity controls at the polling station, which should not undermine the secrecy of the vote, are made more efficient through the issuance of specific voters’ ID documents; the use of biometric measures to identify duplication in records; the adoption of anti-counterfeiting measures for identity documents; the on-line verification of the identity of voters; controlled destruction of identification documents which remain unclaimed by citizens. The use of indelible ink is a good complement to such controls.
