Abstract
The invention relates to a personalisable support comprising anti-forgery devices which are provided in order to indicate every attempt of fraudulent personalization. The support comprises a body () which is on one side equipped with personalization data () which are obtained by carbonization of the base material by means of a laser beam. The anti-forgery devices (), which totally or partly cover these personalization data, draw a pattern () along which bubbles () are created whose density (d-d) varies depending on the degree of carbonization of the areas (-) which are covered by the pattern.
