Marksense systems employ a ballot card on which candidates and issue choices are preprinted next to an empty rectangle, circle, oval, or an incomplete arrow.
Voters record their choices by filling in the rectangle, circle or oval, or by completing the arrow.
After voting, the voters either place the ballot in a sealed box or feed it into a computer tabulating device at the precinct. Marksense technology has existed for decades and been used extensively in such areas as standardized testing and statewide lotteries.
