Just asking. Do you put the ballot in a box or does it go through a machine?
Both, the ballot is a mark sense form, you fill in the chosen bubble. You insert your ballot into a scanner and you get a green light when it is read and counted. The paper ballot goes into a box. If the machine count and the paper ballot does not match, they can hand count the paper ballots.
Kansas used to have the touch screen machines, but they are subject to error, either a mechanical fault or malfeasance. I don't know where they went (probably to Chicago), but Kansas changed to the paper ballot with machine reading. Very secure IMO.
