DRE With Voter-Verified Paper Trail (VVPT)
DRE System With VVPT:
This is typically is a touch-screen DRE system designed to capture
voter choices both internally in electronic form and,
contemporaneously, on paper as a voter-verified record. It is a
defining characteristic of a DRE system with VVPT that voters are able
to see and confirm the accuracy of the paper record although that
record is often not physically handled by voters and remains at the
polling place, mechanically stored within or near the DRE machine used
to cast the vote.
DRE systems with VVPT
include those that ensure voter privacy by automatically separating
and randomizing vote selections to store and those with reel-to-reel
designs. Proponents of DRE with VVPT systems anticipate that in the
case of a discrepancy between the electronic vote stored internally in
a DRE system with VVPT and the voter-verified physical ballot securely
stored within or near the machine, laws, procedures and regulations
would dictate that the physical ballots are the votes of record.
There are two subclasses of DRE with VVPAT that affect ballot secrecy:
- Those that cut the
ballots into individual sheets and deposit them separately
- Those that use a
reel-to-reel or other ordered way of storing the ballots
