Punchscan is the first vote capture system to offer fully end-to-end (E2E) verifiability of election results.
Punchscan moves beyond ordinary paper audit trails offering a far more robust and available way for voters to become involved in the election oversight process.

What is E2E, and why is it Important?
End-to-end cryptographic independent verification, or E2E, is a mechanism built into an election
that allows voters to take a piece of the ballot home with them as a receipt. This receipt does not
allow voters to prove to others how they voted, but it does permit them to:
Verify that they have properly indicated their votes to election
officials (cast-as-intended).
Verify with extremely high assurance that all votes were counted
properly (counted-as-cast).
Voters can check that their vote actually made it to the tally, and that the election was conducted fairly.
Punchscan is an international open-source project headed by esteemed cryptographer David Chaum and includes researchers from the University of Maryland-Baltimore County (UMBC), George Washington University (GWU), University of Ottawa (UO) and University of Waterloo (UW).
