It does nottake a genius to have a paper trail for voting,think about it carefully.
All you do is have at each polling station a secure sealed certified computer, that A; prints out a ballot sheet which has a serial number allocated against it (done in sequence). B; The voter then goes to a metal template and with a permanent marker blocks out the squares for there candidates choice. C; Then this ballot sheet is scanned into the computer and the printer also prints out a hard copy (this goes into the ballot box). D; The voter then takes there original with them.Now you have an original and a copy in the ballot box plus the computer scanned version (the voting program can at each station calculate each candidates votes and place on a secure hard drive).E;The whole computer system and ballot boxes then go to a central station for auditing plus the voter has there original...any recount can request each voter to return for a check of there origianl ballot...how simple! Virtually foolproof and unquestionable as the voter has there original (and official could even stamp the form somewhere as proof of the originality of the sheet and its number,so no cheating.
