2006. In 2004, 4,812 voting machine problems were reported to a system managed by Verified Voting and Computer Professionals for Social Responsibility. Most of these problems were in states which were primarily using direct-recording electronic voting equipment as of 2006. Security reviews and audits are discussed below. Online, email and fax voting Email, fax, phone apps, modems, and web portals transmit information through the internet, between computers at both ends, so they are subject to errors and hacks at the origin, destination and in between. Election machines online As of 2018–19, election machines are online, to transmit results between precinct scanners and central tabulators, in some counties in Florida, Illinois, Indiana, Iowa, Michigan, Minnesota, Rhode Island, Tennessee and Wisconsin. Receiving ballots online In many states, voters with a computer and printer can download a ballot to their computer, fill it out on the computer, print it and mail it back. This "remote access vote by mail" (RAVBM) avoids transmitting votes online, while letting distant voters avoid waiting for a mailed ballot, and letting voters with disabilities use assistive technologies to fill in the ballot privately and independently, such as screen readers, paddles or sip and puff if they already have them on their computer. The voter also receives a form with tracking numbers and a signature line, to mail back inside or outside the envelope with the ballot, so staff can review eligibility of the voter and prevent multiple votes from the same voter. Many states accept mailed ballots after election day, to allow time for mail from distant voters to arrive. The printed ballot may show just the choices and a bar code or QR code, not all the candidates and unvoted contests. The voter's choices are not put online, which is an advantage for the voter's privacy. However the system does not work for people who have no printer or no computer. For people, such as soldiers, with a shared computer or printer, votes can be divulged by keystroke logging, by the print queue, or by people seeing ballots on the printer. Alternatives for distant voters are to get a paper ballot from the election office or the Federal Write-In Absentee Ballot. Alternatives for local voters with disabilities are to use a ballot marking device (BMD) at a polling place, if they can get there, or have election staff bring a BMD and ballot box to the voter.
