All voters in Maryland use the same voting system. For polling place voting, voters use a touchscreen voting system by Premier Election Solutions (AccuVote-TS). With a touchscreen voting system, a voter touches the screen to make, change, and review selections and cast a ballot. A demonstration of how to vote on Maryland's touchscreen voting system is available.

For absentee voting and provisional voting, voters use a paper-based optical scan voting system (AccuVote-OS or Model ES-2000). With this system, a voter is issued a paper ballot and completes the oval next to the candidate or ballot question response for which the voter wants to vote. At the local board of elections, the ballot is fed into a scanning unit, which reads and tabulates the selections made by the voter.
