Fist off where I've voted they switched from punched cards to scanning paper ballots. It's all typically run by three middle aged women with a printed book of who's registered to vote. You just tell them your name and they find your entry and you sign it. That's a system I trust and it has the positive of civic engagement. And fundamentally it's not broken.

You now also have the option of mailing in a ballot. That's easier to corrupt I'm sure. But at least it's still paper.

All the fully computerized systems seem really really sketchy to me. Especially in low trust cultures where underhanded stuff is normalized.
