Abstract
An IC card includes a first visible layer comprising a nonmetallic natural material having a physical structure including a unique visual pattern. The IC card further includes a storage device configured to store a reference image of the unique visual pattern. The reference image is a scan of the unique visual pattern. The reference image is configured to be visually compared with the unique visual pattern for authentication. A second layer is included on a bottom surface of the first visible layer. The first visible layer and the second layer are laminated together. Each of the second layer and the nonmetallic natural material of the first visible layer have a same size to define a shape of the IC card.
