About e-voting E-voting as a digital alternative to ballot boxes and postal voting
For a number of years, electronic voting trials have been conducted in Switzerland. In the future, voters will be given the opportunity to vote electronically as a third voting option in addition to the physical ballot box and postal voting. The precondition is that their canton participates in the trials.
Swiss e-voting compared to other countries
In Switzerland, e-voting refers to voting via the Internet, also known as “remote online voting” or “Internet voting“. In other countries, however, e-voting can mean that you cast your vote in a polling station via an electronic voting machine that can be connected to the Internet.
How can voters use the e-voting system?
To make use of electronic voting, Swiss voters receive several security codes by post together with their postal voting or election documents. One code enables them to log in to the e-voting platform of their canton. Other codes are used to check a vote has been cast, to confirm the choice made and to check whether the vote cast has been successfully received by the electoral authority.
Once a vote is cast, it is encrypted in the system, anonymized and stored in an electronic ballot box. Only the relevant canton’s electoral commission can open the ballot box and decrypt and count the votes.
Trials with e-voting
The e-voting system developed by Swiss Post can be used for votes in the cantons of Basel-Stadt, St. Gallen and Thurgau until May 2025, according to the initial authorization of the Federal Council. The Canton of Graubünden also facilitates e-voting with the Swiss Post system as part of the legally defined trial operation. For the first time since 2019, a part of the electorate can vote electronically again in accordance with the legal basis for e-voting. In Switzerland, 15 of the 26 cantons gained experience with e-voting between 2003 and 2019. Different systems were used. The previous Swiss Post system was used successfully in the cantons of Fribourg, Thurgau and Basel-Stadt until 2019.
The first system with complete verifiability
Swiss Post’s new e-voting system offers complete verifiability. This means that the electoral authorities and independent election observers can check whether votes have been manipulated in the electronic ballot box when counting votes. The check is comparable to the recounting of physical ballots. This enables independent control and verification of the ballot by the cantons. To date, no system with complete verifiability has ever been used in Switzerland. Swiss Post has developed open-source verification software in its Cryptography Center that serves as a tool to help the cantonal electoral authorities carry out a complete check on the electronic ballot. This development is a pioneering achievement. To date, no software like it has ever been used anywhere in the world for e-voting systems.
