CHVote: an open-source electronic voting system from Switzerland
https://republique-et-canton-de-geneve.github.io/chvote-1-0/index-en.html
The electronic voting system CHVote is a concrete answer and a real breakthrough in digital technology and e-government.
This system is the fruit of a partnership between the State Chancellery and the General Directorate of Information Systems (DGSI) of the Department of Security and Economy (DSE) of the Geneva Canton.
The State of Geneva is pioneering in the e-voting domain with over 100 polls successfully accomplished since 2003.
CHVote, entirely developed, hosted and operated by the Geneva Canton is today one of only two accredited electronic voting systems by the Federal Council in Switzerland. It is offered to nearly 125000 voters in 4 cantons (Geneva, Bern, Lucerne and Basel), as much for voting as for electing at the communal, cantonal and federal levels. It also allows people with disabilities to participate in the polls.
