The accessibility and accuracy of DREs, however, are offset by a lack of transparency, which has raised concerns about security and verifiability. In most of the DREs used in 2004, voters could not check that their ballot was recorded correctly. Some DREs had no capacity for an independent recount. And, of course, DREs are computers, and computers malfunction. A malfunction of DREs in Carteret County, North Carolina, in the November 2004 elections caused the loss of more than 4,400 votes. There was no backup record of the votes that were cast. As a result, Carteret County had no choice but to rerun the election, after which it abandoned its DREs. Other jurisdictions have lost votes because election officials did not properly set up voting machines.29
