In 2007, Estonia became the first country to allow online voting in a nationwide election, following two years of a pilot program.
Modeled after online banking, the system requires smart-chip enabled ID cards. Estonians can digitally register with the card, punch in a PIN number and cast their vote.
Online voting is only available in advance, so Estonians have to go to polling stations on election day itself.
