The Mercuri method is the most popular and notable form of a voter verified paper audit trail (VVPAT).
An election using this method would benefit from the efficiency of the DRE machines with the confidence instilled by a physical record.
[2] The method works by displaying a paper vote record under glass or clear plastic after a voter indicates their choices.
They finalize their vote by pressing a button or pulling a lever, and the paper record is stored.
The Mecuri method is named after Rebecca Mercuri who described it in her PhD thesis at the University of Pennsylvania in 2000.
