Canada does the same. Paper is extremely hard to scale an attack against and the best electronic voting machines are basically gigantic million dollar pens.
Our method is a bit different. I worked a federal election when i was 18 and each booklet had ballots counted against the stubs. Each booklet had a serial number we had to verify against and requesting more was a whole procedure. Me and the other poll worker each counted our stack and swapped. Each party had an observer there and while we didnt need to recount i think they could requestcit if they wanted?
