Why not use a system where a paper is punched and the punch is registered electronically? The card could be serialized to avoid fraud. Instead of a touch screen, display the voting options on a screen next to the card. IMHO, this would solve numerous problems associated, but still provide a "paper trail" to accurately determine how a voter voted. Heck, the cards could be provided blank and the device could even print the options on the card immediately prior to voting to ensure accuracy.
