The new VSAP system is
a touchscreen Ballot Marking Device or BMD, which prints out a computer-marked paper ballot summary of votes selected via the touchscreen, before using another computer, an optical-scanner, to read the non-human readable QR Code that is also printed on the ballot summary. The QR Codes are used to tally votes. While the QR Code (a type of barcode) cannot be verified for accuracy by voters, it is also impossible with such systems to know if
any voter has even verified the human-readable portion of the ballot summary at all, much less correctly, after an election.
Studies reveal that most do not verify computer-marked ballots at all, and that of the minority who do, most don't recall the details or selections on the ballot they voted just moments earlier. That's just one of the
many reasons why most cybersecurity and voting systems experts
warn against the use of such systems which are now proliferating --- and sometimes replacing verifiable hand-marked paper ballot systems --- in many states and counties across the country before 2020. (The list of states where counties or the entire state are moving to BMD systems include a number of key battleground states. Such systems are planned for use next year, or are already being used, in OH, WI, PA, TX, WV, KY, NY, NJ, KS, TN, IN, SC, NC and, yes, CA, unless the public prevents these plans.)
