A method for uniquely marking an object, wherein a random distribution of individual pigment domains is applied to a surface of the object, and wherein a list of distances of the individual pigment domains from one another is measured and stored in a database. Also a corresponding method for identifying an object by: capturing an image of the pigment domains, identifying the two-dimensional coordinates of each pigment domain captured in the image, determining the two-dimensional distance of each pair of two pigment domains and/or the angle of each triplet of pigment domains, storing the distances and/or angles determined in the step before in a list, storing the list in the database, the list enriched with meta-information about the manufacturing and/or finishing parameters of the object, applying a database identification as an information unit to the surface of the object, the information unit uniquely assignable to the database.

A transaction card construction and computer-implemented methods for a transaction card are described. The transaction card has vector-formatted visible information applied by a laser machining system. In some embodiments, systems and methods are disclosed for enabling the sourcing of visible information using a scalable vector format The systems and methods may receive a request to add visible information to a transaction card and capture an image of the visible information. The systems and methods may capture data representing the image. The systems and methods may also determine an ambient color saturation of the image. Further, systems and methods may translate the image based on the ambient color saturation of the image. The systems and methods may also map the translated image to a bounding box and convert the mapped image into vector format. In addition, the systems and methods may provide the converted image to a laser machining system.

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.
