I bought this to hold my kids' and my passport. However, since mine is EXTREMELY filled with extra pages and thicker than a "normal" passport, I shall need to get a separate one or at least find one that can contain all the pages and extra sheets. It does work. I had a friend test this at airport security with one of their RFID readers. Unless the imbedded computer chip is exposed, no one should be able to get your information.
