It's no more than a souvenir

Here in Ohio there's a print-out screen on the right side. After casting a ballot the voter can watch his selections being printed in real time out and rolled up into the machine.

At the end of the day that roll is removed and signed by all four poll workers (2 dems 2 Repubs), then locked into a steel box and sealed with a numbered security tag. That serial number is recorded in the book and sent along to the Board Of Elections by one dem worker and one repub worker.

Then that record is stored there under lock & key for two years in case of a dispute or hand recount. This discourages cheating because if someone were to somehow corrupt the count there's that paper trail waiting to bust them. Since everyone involved has to sign off on each step, it's easy to find where things went wrong and who to blame.

Computer voting can work if it's done correctly.
