The shield and key design is one of our most popular ID card holograms. When applied by peeling off the wax paper backing and sticking onto your ID badge this microfilm overlay will add holographic imaging to your ID Badge for increased security. This is able to bee seen when viewing the card from an angle. Quaintity discounts are available for bulk purchases. This overlay has a large eagle in the center which can only be seen under an ultra violet black light.
