This is my job. I work for a major children's hospital and I scan Id's all day. We scan everyone. It's a program called Easy Lobby. There is no reason why Disney couldn't use it. It would expensive to start up due to license fees for each scanner. They could require Names and birthdates for ticket purchase and run them at that time not park entry. It's just a shame these scumbags can't be detected before they're caught and registered.
