An optically writable holographic card, an optically writable holographic media, and a method of making the media are herein described. The card has a media region that includes an optically writable material. The optically writable material has an holographic embossment such that an holographic image is producible by the optically writable material. The media includes an holographically embossed first layer. An optically writable, optically readable second layer conforms to the embossment. The holographic image is generable by the second layer. The method includes producing an holographic embossment associated with an holographic image. An optically writable layer is conformed to the holographic embossment. The holographic image is viewable in response to illuminating the optically writable layer. The optically writable layer is optically readable. The optically writable material on the card may support optically written digital data and an optically written image, or an optically written image having embedded digital data. |
