French ballot boxes are transparent. And you can only insert your envelope when the person in charge presses a lever to open the entry slot. Even for a magician / trickster it would be hard to attack.

But the important thing is that anybody with two eyes (or at least one) and some basic cognitive abilities can understand what is going on and make sure that there is nothing shady going on.

Basically any citizen can take a sandwich, a bottle of water and spend the day in his local voting place from beginning to end and have a reasonable certainty that the voting process was fair.

I think this is very important for democracy. It does not solve other problems (fair access to media...) but at least the voting part is reliable.
