i read somewhere that the ballots were watermarked to prove if ballots are legal, and if the legal votes got to the location and person they were sent to to begin with, and something about them being gps'd so they could be followed and found if not where they should be (in the count rooms by end of election time...)  best explanation about this i have yet heard is from steve pieczenik on utub--already removed bc they cant handle the truth; saw the vid on some other platform also,  but all the emails i sent to myself and others sith the links are gone😡 but go to :  https://theamericanreport.org/2020/10/31/biden-using-scorecard-and-the-hammer-to-steal-another-u-s-presidential-election-just-like-obama-and-biden-did-in-2012/ to read article about the hammr that bo and bidn and ckapper? and brennan used to illegally surveil, as well as flip votes, not only used in this election but also since 2012..... also, look for the links about the book 'the hammr is key to the coup'--chapters 1-3 links (very interesting!) these traitors are about to be exposed and on way to gitmo🙏🏻
