Fill in the bubble, or connect the line, or whatever electronically read paper hand marked ballot systems are also better because they are far more robust.
With ANY kind of complicated machine required for filling in the ballots the machine can easily become a choke point.
When all you need to fill out the ballot is a reasonably dark marking instrument, a vaguely flat dry spot, and enough light to read it is far easier to scale up some or to shoulder through problems.
I was once at a ballot place in California and, due to a logistical screw-up they had very few pens. The 8 or so people in the line inside the building happened to be holding 5 pens good enough for ballot filling and gave them to the polling station while one of the poll workers ran off to a drugstore to buy a sack of pens.
I was once at a polling place who’s scanner machine broke. They just had a backup cardboard box, and would later take the ballots back to the central office for counting.
One time in Seattle the power went out at a polling place. As it was still daytime they pushed the little tables over near the windows.
With any electronic vote entry system each of those polling places would have been crippled.
