Exactly. Paper ballots are auditable (i.e. recountable). It is VERY difficult to devise a paper-free scheme that can be sorted out after the vote if (i.e. when) something goes wrong with the vote tallying.
Fortunately for those elsewhere, we here in the US have tried the experiment of embracing electronic voting without really thinking through the consequences. The bottom line: Generally electronic voting works, but there are lots of ways it can fail. And once it fails it can be really difficult to sort things out. If they can be sorted out.
What does seem to work reasonably well is paper ballots that are machine read and tallied electronically. If the tallying process breaks down somehow or questions arise about the integrity of the count, the ballots can be counted by hand
