Physical coercion is possible also with paper ballots. A modern approach is to ask voters to shoot a picture to their voted ballot. No picture, big trouble.
For that reason taking a picture of our own voted ballot is a crime in Italy. Obviously is a crime also to ask people to do that. Cameras are not allowed in polling places and smartphones should be left outside the polling booth. However nobody asked me to do that the last time I voted. I remember they did many years ago. There were many phones lined up on the desk of the president of the polling place.
