Voters will be allowed to post selfies on the Internet after casting their ballots in the presidential election on May 9 showing which candidates they chose.
The decision is based on a change in the election law in February that also allows overseas Koreans to take part in the vote in this snap election after ex-President Park Geun-hye was ousted.
Voters can also post photos of themselves with their arms crossed in front of posters of candidates they did not choose.
Taking pictures of ballots in election booths will remain banned.
Also, voting will be extended for two hours until 8 p.m. like other by-elections because the last president’s term ended prematurely.
This is also the first presidential election that permits early voting on Thursday and Friday.
On election day, candidates will be allowed to woo voters via social media and mobile phone text messages. So far any kind of campaigning on election day was banned.
But candidates or their staff are still prohibited from hitting the streets on the day, and public servants, minors or high-ranking military officers are not allowed to take part in any campaign activities.
