PERFECT Project Voting Machine Photographs
Over the past several years, we have acquired examples of a number of electronic voting machines. While not the primary focus of our current NSF-funded project, we study these systems on an ongoing basis for a variety of research and educational purposes. Three of the systems below are particularly noteworthy because they are used in or near the Pennsylvania counties where Lehigh University is located: Danaher (Bucks County), Diebold (Lehigh County), and Sequoia (Northampton County).
