A lot of the states using the Diebold machines do require them to have paper receipts. The one I used did have a paper receipt that allows you to confirm the machine did not do a mistake. Basically at the end of the touch screen voting, it will print out all your votes and force you to confirm them. You can not take the receipt with you or modify it as it is behind glass in the machine. But THERE IS A PAPER TRAIL. Unless you live in a dumb state that does not require paper trails, all this talk of hacking elections is really off base. Just the spreading of ignorant paranoia. Election officials can go back through the receipts and confirm the machine's results. And many of the states also require this check on a small percentage of the machines to make sure they were programmed correctly.
The idea of getting a receipt to take with you is useless. People can easily manipulate the receipts and it would also invalidate the principle of private voting. It would just perturbate the problems of mail-in ballots. Many campaign managers go to senior care centers, homeless shelters, and similar places and basically "help" fill out mail-in ballots for people to sign. I can see an underground vote buying system taking root if the machine gave out take home receipts.
