I'm developing a Facebook app for a tab but I encountered the problem. I can't get the Facebook UID from the user is seeing my tab.
I'm working on a poll system and I would like to use a personal voting system since I cannot use Facebook likes to achieve this.
The users should only be able to vote once per Facebook account.
Is there a way to have the track of user votes this way?
Thanks <3

This could be using user ip or cookies.
