ABSTRACT:
The invention relates to a method for the recording of data, in particular, personal data on and/or in a data support, by means of electromagnetic radiation. A corresponding data support is made ready, on and/or in which a dye is at least locally provided and said dye is irradiated by means of said electromagnetic radiation of at least one wavelength range, such that a change in the color of the dye by bleaching occurs in the region of the irradiation. Said color change may be determined by machine and/or by the human eye. An improved counterfeiting and manipulation security for the data support is thus achieved.
