The invention relates to a method and a device (100) for forming a two-dimensional or three-dimensional micro-structured identification structure (200) in a defined surface region (12) in a surface (11) of a component (10) or product.

The disclosure relates to devices, systems, methods and computer readable media for providing network management of remote card handling, and physical manipulation. More particularly, the disclosure is directed to networked devices, systems, methods and computer program methods for remotely, physically modifying a card while leaving a physical record of the modified card for inspection and validation and delivering the manipulation results to a user, and/or other third parties, for example, scratch lottery cards and ballot cards.

An article allows an engraved code to be detected. The engraved code includes a plurality of dot dented portions defined on the article. Each of the dot dented portions has a quadrilateral pyramid shape with a coating layer on a prior stage dented portion having a quadrilateral pyramid shape. Corner dented portions dented at acute angles outward along a diagonal direction are defined at four corner positions of an opening peripheral edge portion of the prior stage dented portion.

In accordance with a first aspect of the present disclosure, a method for providing a code pattern which is readable by a sensor is conceived, the method comprising: defining a plurality of coding positions as a subset of positions in a two-dimensional matrix; including in said subset a plurality of positions which are diagonally adjacent to each other; selectively creating coding marks, such as coding dots, at the coding positions. In accordance with a second aspect of the present disclosure, a corresponding code pattern is provided.

To enable simple identification of a workpiece with little effort during machining of a workpiece on a processing machine, a marking method is provided which is to be carried out via the processing machine. The method includes a) providing a tool on a rotatable tool holder of the processing machine, b) relative linear movement of the tool holder and the workpiece along a line on the surface of the workpiece, and c) controlling the distance of tool holder and workpiece during the linear movement, so that a pattern of markings is produced along the line by machining with the tool to form the identification mark on the surface of the workpiece. Furthermore, a readout method, a machining method and a processing machine configured for carrying the method are provided.

A managed article that allows an engraved code to be detected. The engraved code including a plurality of dot dented portions is formed on a managed article. Each of the dot dented portions has a quadrilateral pyramid shape with a coating layer formed on a prior stage dented portion (15) having a quadrilateral pyramid shape. Corner dented portions (25) dented at acute angles outward along a diagonal direction are formed at four corner positions of an opening peripheral edge portion (22) of the prior stage dented portion. This configuration leads to detection of the dot dented portion as a quadrilateral dot. In addition, the present configuration allows a coating material to be introduced into the corner dented portions at the time of the coating, thereby contributing to preventing or reducing inward projection of the coating layer at the corner positions of the dot dented portion.

A method for manufacturing flexible printed circuits for smart card modules, wherein a complex material is provided. This complex material includes an assembly including at least two different-colored strata. Zones of this assembly are visible through the layer of electrically conductive material. This manufacturing method includes an operation that consists in laser etching at least one of the two different-colored strata over a portion of that zone of the assembly of strata that is left visible, so as to reveal the color of the other of the two different-colored strata. Printed circuit manufactured by this method. Module and smart card including this printed circuit.
