Electronic voting, or e voting, is voting in an election or referendum in which electronic technology is used to cast, record or count votes. The term covers several technically different systems and should not automatically be treated as synonymous with internet voting. International IDEA describes electronic voting broadly as the use of electronic means in elections to cast or count votes.
Systems can include electronic voting machines located in polling stations, systems that scan paper ballots, direct recording electronic machines and remote internet voting. The defining feature is the use of information and communications technology in the voting process. Consequently, a paper ballot scanned electronically for counting and a vote transmitted over the internet are both technologically assisted electoral systems, but they involve very different security, privacy and administrative characteristics.
One important distinction is between polling place electronic voting and remote electronic voting. Polling place systems operate in a controlled electoral environment, where election officials can supervise the voter and equipment. Remote electronic voting allows a voter to cast a ballot from a location outside the polling station, potentially using a personal computer, telephone or mobile device connected to a network. International IDEA identifies direct recording electronic machines, internet voting and other electronic mechanisms as different forms of e voting. The distinction matters because a supervised voting machine can benefit from physical security and election staff, whereas remote internet voting introduces additional challenges involving the voter's device, network, authentication, malware, coercion and the security of the surrounding environment.
Electronic voting can be designed to perform several functions. A voting machine may display candidates and record the voter's selection directly. A scanner may read a paper ballot and transmit or store the resulting data electronically. An electronic poll book can verify eligibility without itself recording the vote. An electronic tabulation system can process and transmit results after ballots have been cast. These functions should not be conflated.
International IDEA distinguishes electronic poll books, electronic tabulation systems and e voting because they perform different tasks within the electoral process. A country can therefore use significant election technology without allowing voters to cast ballots electronically. The presence of computers in an election does not by itself mean that the election uses electronic voting.
The principal potential advantages of electronic voting include faster processing, accessibility features, reduced dependence on paper, automated counting and potentially improved convenience. Properly designed systems can assist voters with disabilities, provide interfaces in different languages and reduce certain forms of manual counting error. International IDEA notes that electronic voting can speed the processing of results and increase accessibility and convenience when properly implemented. At the same time, these benefits depend on reliable technical infrastructure and appropriate electoral procedures.
Electronic systems can introduce new failure modes that do not exist in purely paper based systems. The relevant question is therefore not whether technology is inherently better or worse than paper, but whether a particular system provides sufficient security, transparency, auditability, accessibility and resilience for the electoral context in which it is used.
Electronic voting presents distinctive security and transparency challenges. Software errors, malicious code, compromised equipment, network attacks, insider threats, supply chain vulnerabilities and failures in system configuration can affect the integrity of an electronic election. Remote voting creates additional concerns because election officials cannot fully control the voter's device or physical environment.
International IDEA has emphasised that some electronic voting systems can be difficult for voters and administrators to understand and that the integrity of the process may become dependent on a relatively small group of technical operators. Paper based processes can expose different risks, including physical tampering, ballot handling errors and counting mistakes. Electronic and paper systems therefore involve different risk profiles rather than a simple division between secure and insecure methods.
Verifiability is a central technical concept in electronic elections. Election authorities and observers need mechanisms for determining whether the recorded result corresponds accurately to the voters' choices. Some systems use voter verified paper audit trails, in which an electronic machine produces a physical record that can be audited or recounted. Other systems rely on cryptographic or software based verification methods. The design question is how to establish trustworthy evidence without compromising ballot secrecy.
A system that produces a rapid numerical result but cannot provide an independently meaningful audit trail can create different confidence problems from a paper system in which ballots can be physically inspected. International experience therefore places considerable emphasis on auditability, transparency, testing, procedures and independent scrutiny.
Electronic voting is not currently used in one uniform global model. Some countries have adopted polling station machines extensively, some use electronic technology for limited parts of the process, some permit remote internet voting for particular voters and others retain predominantly paper based systems. International IDEA's recent work notes that online voting has become an established practice in some countries while remaining experimental, restricted or controversial elsewhere.
The reasons for adoption differ and can include accessibility, overseas voting, administrative efficiency and modernisation. Decisions about technology are also influenced by legal frameworks, electoral management capacity, public trust and cybersecurity conditions. Consequently, statements about electronic voting should identify the specific technology and jurisdiction rather than treating all e voting as one system.
Electronic voting is therefore a broad category of election technology rather than one particular machine or procedure. It includes technology used to cast, record or count votes and can operate in supervised polling stations or remotely. Its potential advantages include accessibility, speed and administrative efficiency, while its principal technical challenges include cybersecurity, software integrity, transparency, auditability, privacy, reliability and public confidence.
Electronic voting should be distinguished from electronic voter registration, electronic poll books and electronic result tabulation because these technologies perform different functions. The most accurate assessment of an electronic voting system requires examination of its legal framework, hardware, software, authentication procedures, ballot secrecy, audit mechanisms, testing arrangements, contingency plans and independent oversight rather than relying on the generic label e voting.
