> Paper ballots are not an optimal democratic way of conducting voting. The whole process is time and resource consuming and disenfranchises the less privileged.
That really depends on how it's implemented. Living in Switzerland I get to vote a lot.
About a month before an election or referendum I get the voting slips in an envelope that can be reused to send them back, postage paid.
The slips are placed in a sealed envelope and a signature has to be provided on a slip. The same slip I need to provide at the polling station should I chose to vote in person.
Results are in in a couple of hours after polling closes, except for more complex elections (usually election of parliament, which has a few idiosyncrasies). But even there, results are in the same evening.
The actual procedure may slightly differ by Canton.
It may be resource intensive, but election integrity and speed has a price, which I think is worth it.
And nobody is disenfranchised since you pop your vote into the next letterbox for free.
