When a centralised electoral register is available (and reliable), an online verification of the identity of voters may also prevent multiple voting. In Lithuania, where since 2018 voters are allowed to cast their vote in any polling station in the country regardless of their place of residence, polling station officials use computers connected to the nationwide electronic voter lists to verify the eligibility of voters and to forestall multiple voting. Additionally, voters are required to sign paper voter lists in the event that the electronic system fails.
