Advice on Psychic Paper

One of my players wants an item like the Psychic paper from Doctor Who. For those who don't know it, it is basically a paper that you can flip up and it will show something that would allow you access to a place or information by taking information from the mind of each person seeing it. Now clearly that would be to powerful, especially since they are only level 6 at the moment.

I proposed a ring that can turn into a signet ring of any noble house, provided the wearer knew how their heraldry looked and thus requiring a Society check to determine how good of a copy this was. I don't know what level this item would be and if it needs to be tweaked, either buffing or debuffing it?

Either way my player wasn't really happy with the concept because it wasn't really the psychic paper. At the time I told them the psychic paper is to powerfull. That is also why I am here, is there a way to make it work, and in that case at what level?

Any help would be appreciated!
