In a method of manufacturing a multilayer chip component according to an aspect of the present disclosure, laser processing is used for forming dots of a two-dimensional code. This laser processing is laser processing with respect to a laminate substrate in a state before baking is performed, and an impact at the time of processing is absorbed to a certain degree due to elastic deformation of the laminate substrate. For this reason, according to the manufacturing method, occurrence of cracking can be curbed compared to laser processing with respect to an element body in a state after baking is performed.

Technology for managing objects. A method is applied to a set of objects, for example, in view of commissioning such objects. The method includes patterning a surface of each object of a set of objects to be managed. The patterning is accomplished by using hard particles to make indentations in a surface of each object of the set of object, with the pattern formed on each object being a unique physical fingerprint that can be used to identify the object when performing various manage method(s) on the objects

A method for authenticating an object, particularly a security element for protecting value documents, ID documents and products, as well as a security element, a security document, a reader, an individualization device and a server for such a method. The method involves the steps: dividing a first code element into at least one first partial code element and one second partial code element, storing the second partial code element, arranging the first partial code element and/or a second code element on and/or in the object, jointly machine-capturing the first partial code element and the second code element by means of a reader, extracting the first partial code element and the second code element from the data captured by the reader, accessing the stored second partial code element using the second code element as a key, checking whether the code element resulting from merging the extracted first partial code element and the stored second partial code element corresponds to the first code element.
