• Non-Remote Voting Machines: An electronic device used to cast a vote, which records the ballot choice made on a local medium, e.g. the machine itself or a printed ballot.
• Supervised Environments: A voting machine used in a location where election staff is present to manage the voting process, such as a polling station.
• Unsupervised Environments: A voting device used in a location where no election staff is present to manage the voting process, such as any computer the voter uses for Internet voting.
