For people not familiar with voting in Switzerland, we already trust the Swiss Post, given that most ballots are mailed in. I've never been at a physical polling booth in my life, and we vote at least four times a year.

We also have an online voting platform already, which has been launched by the canton of Geneva in 2003. It has known several upgrades, security audits, and has been targeted by hackers a few times. It's proven quite successful and it is used by a few cantons besides Geneva. Sadly, due to a lack of federal support, Geneva doesn't want to bear the costs anymore.
