Here is a link to an article in the Lancaster PA paper about the sad status of electronic voting in PA. The Federal money to buy voting machines is only available under Dec. 31. PA. has only certified one brand of voting machine, and it does not have a paper trail.
PA. officials said they don't want a paper receipt that a voter can take with them, because it might lead to sale of votes. This easily could be resolved with a system that makes the paper receipt visible to the voter, but then drops it into a secure box. After all, the value of the receipt is in being able to check the boxes, not in having all the voters bring their receipts back in.
