Aside from cryptographically sound and open source end to end verifiable options there is one simple alternative still used in many other countries and jurisdictions:

1. voters mark paper ballots 2. observers from all parties watch the counting 3. results are tallied publicly

Yes, this is very much feasible; and no, this is not the right domain to be ingeniously efficient and cost sensitive. US being the richest country in the world or some such, etc..

That won't stop the election cranks. In the 2020 election there were accusations of election fraud centered around workers "stuffing" ballot boxes or otherwise acting suspiciously.
