Beschreibung
Zusammenfassung:	A data carrier (1) extends along an extension direction (E) and comprises at least one carrier body (2) and at least one processing layer (3). The processing layer (3), at least in an unprocessed state of the processing layer (3), comprises one or more reactive elements (4) and one or more unreactive elements (5). The reactive elements (4) are configured to interact with impinging electromagnetic radiation (R) upon a processing of the processing layer (3). The processing layer (3), in a processed state of the processing layer (3), comprises one or more reacted elements (6) being generated from the reactive elements (4). The processing layer (3) in the processed state furthermore comprises one or more further reacted elements (7) being generated from one or more of the unreactive elements (5) upon the interaction of the reactive elements (4) with the impinging electromagnetic radiation (R) and furthermore comprises one or more unreactive elements (5) remaining non-interacting. The processing layer (3) in the processed state furthermore comprises at least one personalization element (100), which personalization element (100) comprises or consists of the non-interacting unreactive elements (8).
