This overlay instills two effective security features onto your ID Badge to make sure no one can replicate your cards. The image as shown above is printed onto a specialty microfilm with a holographic effect which does not block or obstruct the design of your card but can be seen at an angle by capturing light. The film is applied like a specialty sticker for an easy install but permanently bonds once applied. The large eagle seen above is printed onto this same film with UV ink and is invisible to the naked eye regardless of angle, this only appears when a blacklight is shined onto your card.
