ROCK ISLAND, Ill. (WPVI) -- Two states have come up with a way to stop voters from snapping pictures in the booth.
It is illegal in many states to take a picture of yourself while voting.
So polling stations in Iowa and Illinois are setting up selfie walls.
When people finish voting, they can snap a picture themselves there, not in the booth, to post as proof that they performed their civic duty.
