Although Miami-Dade County paid for his trip, Leahy said representatives from the Riverside system's manufacturer, Sequoia Pacific Systems, showed the supervisors around. Before Sequoia can sell the voting machines in Florida, it must win certification by the Florida Division of Elections. The system's most unusual feature is its ability to print a receipt confirming selections. The machines can be programmed either to list the specific candidates picked or simply confirm that the voter voted in a particular race. Leahy expressed reservations about that feature, concerned that it could lead to voter fraud.
Electronic voting is the most expensive of the technologies being considered.
