Scantegrity is an integrity assurance add-on for any conventional optical-scan voting system. It gives voters the ability to verify that their votes are recorded and tallied correctly without altering the basic form of the ballot or how voters use it.

Scantegrity borrows its clockwork from the Punchscan voting system. But instead of being a complete voting system, Scantegrity aims to provide a low-footprint audit companion solution for any current optical scan voting system. Its special audit symbols are included unobtrusively in the ballot printing, out of the way of what voters need to do—vote.
