I'm about your age and I live in Italy (not exactly the most advanced democracy ever). We still vote with pencil and paper. I see no issue with that: I go in with my voting document (that I received via mail), I vote, I go out. It takes 5 minutes of my time, and it happens every few years.

The reason why young people don't vote, I think, is mainly because indifference towards politics and/or the candidates, not because it's a hassle to vote.
