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 present invention is an imprint device for imprinting a unique identification mark on a surface of an object with imprinting particles of different sizes that increase uniqueness and without the need for electric power. The imprint device includes a vertical member, a hammer member, a trigger assembly, a charging unit, a barrel and at least one pocket. In the operative configuration, a trigger of trigger assembly is activated such that hammer member impacts a cartridge filled with at least one munition of imprinting particles and releases imprinting particles. The imprinting particles travel through the barrel where acceleration is increased and impact on surface is made to form microcraters and unique identification marks. The imprinting particles can be of same size, material and shape or they can be of different sizes, material and shapes or the combination thereof for increasing uniqueness.

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.

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.
