Electronic voting by country
The Uniformed and Overseas Citizens Absentee Voting Act of 1986 requires states and territories to allow overseas military personnel and citizens to vote in federal elections. The Military and Overseas Voter Empowerment Act of 2009 amended this law to require delivery of ballots by at least one electronic means (email, fax, or web site). As of September 2016, submission of ballots is done by mail in 18 states; the other states and the District of Columbia allow submission by one or more of email, fax, or secure web site.
