There’s nothing secure about paper at all. No modern company runs on paper.

Look at these mail-in ballots where signatures have to be verified. Signatures can be faked. And GOP ballots can be thrown out at will because the counter didn’t “believe” the signatures matched.

A machine can be made entirely secure. It all depends how good the design is. It can even do a retinal scan for each vote to make sure the same person doesn’t vote twice. It’s just a matter of how many safeguards you want to put into it.

I'm no stranger to technology. I've written proposals for various ways for people to use cryptographic mechanisms for voting. The biggest problem is registration including verification of uniqueness (isn't registered elsewhere), citizenship, etc.

It can even do a retinal scan for each vote to make sure the same person doesn’t vote twice.

That would require a federal database of retinal scans. Otherwise the same person could vote again in a nearby state. Suffice to say that privacy of the vote and safekeeping of personal information are nontrivial and sometimes conflicting.
