Beschreibung
Zusammenfassung:	The invention relates to a method for identifying articles, wherein article identification data are made available and the article is provided with a hologram representing said data so that the article can be identified by way of an intensity profile corresponding to said hologram. To this end, article-identifying individual data are provided, a hologram profile is digitally calculated using said individual data, and an intensity modulation of the hologram-producing beam is determined. The hologram-producing beam transfers the hologram pixels onto a hologram support that is associated with the article to be identified so that the article can be identified by way of the intensity profile reproduced from the associated hologram support.
