How it works

Ballot pictures

Scanners can make mistakes, or be made to. So every ballot’s picture is public, right next to how the machine counted it. Anyone can look.

Every ballot has a picture.

When a ballot is scanned, its picture is saved and posted with its entry on the public list.

2

Right next to how it was read.

Open any ballot and see the marks on the paper beside what the machine recorded, plus fingerprints of exactly what read it.

Spot a misread.

Here, the bubble for Option A is filled, but the machine recorded Option B. Anyone looking can see it.

A second, independent scanner also rereads every ballot, so mistakes get caught even if nobody looks.

Report it with the key.

The key is printed on the paper ballot, so officials pull that exact ballot and compare it in public. Results are posted within 48 hours. Nobody learns who you are.

Why only the bubbles?

If whole ballots were shown, someone could tell a voter to write a secret word in the margin and then go looking for it. So only the bubbles are shown. Write-ins and margins are covered.
