Abstract
A data medium has at least first and second parts joined together, each having an outer face turned towards the outside and a hidden inner face. At least one of the first and second parts bears, at a certain distance from the outer faces, hidden markings corresponding to personalization data. This first part and preferably the second part of the medium are, at least locally, opaque with respect to through-transmission of laser radiation liable to modify the hidden markings.
