Abstract
A multi-layer body () includes an optically machine-readable identification, wherein the multi-layer body has at least one first plastic material layer with a microscopically fine relief structure shaped in that layer and the optical effect of the microscopically fine relief structure can be altered region-wise for writing in an item of information. First and second regions have different relief structures and form a background pattern (through) which encodes a first item of information and which is partially altered for writing in an individualized code pattern (through) which encodes an individualized second item of information and which overlaps the background pattern. There is also described a method of manufacturing such a multi-layer body and a method of reading the items of information.
