This paper discusses a new concept in overt security called the self-authenticating banknote. The self-authenticating banknote concept is built around the transparent window feature of the polymer banknote. This feature allows the incorporation of transmission based optical devices on a banknote so that the user, by folding the note over on itself and looking through an optical device which is a part of the note itself, can visually inspect and verify certain security features on the banknote. This paper presents a number of examples of optical devices which are presently being developed for this purpose.
