To apply the overlay remove the non-stick backing and simply press onto your existing ID Badge similar to a sticker. These ID holograms are made for standard sized CR80 (credit / license) size cards and form a permanent bond after installed. This design has 9 eagle images which can be seen at an angle without blocking the design on the card itself.
