Abstract
The invention relates to a secure identification document having two main surfaces (S1, S2; S3,S4) and at least one edge, and comprising at least two constitution layers (20,22; 24,26), said identification document allowing preventing any separation of its constitution layers, by delamination for example, said separation being otherwise immediately apparent. The solution of the invention relates to the fact that the at least one edge of the identification document is marked with written data (23; 27) that are etched into said edge by means of a laser beam, said written data overlapping said constitution layers (20,22;24,26; 32,33,34), in order to prevent a fraudulent delamination of said document.
