Ballot marking machine

Polling places in Minnesota have a ballot-marking machine that can help you mark your ballot.

What is a ballot marking machine?

Ballot marking machines give you privacy and independence if you cannot, or choose not, to vote using a pen.

After you put your paper ballot into the machine, it will display your ballot in large print or with a high-contrast background. It can read the ballot to you through headphones, with or without the screen on. It will prompt you to make choices on a braille keypad, touchscreen (if applicable), or sip-and-puff device.

After you make your choices, the machine will fill in the correct ovals on your ballot and return your ballot to you. You can then place the ballot into the ballot box. 

Any voter can choose to use a ballot marking machine to complete their ballot. Except for stand-alone township elections in townships with fewer than 500 registered voters, ballot marking machines must be present in every polling place.
