Abstract
A secured identification document has at least two flexible layers embedding an electronic module. The electronic module includes a flexible substrate on which are positioned an antenna and a radiofrequency microcontroller storing identification data. The radiofrequency microcontroller is electrically connected to said antenna. The secured identification document has the at least two flexible layers locally joined together by means of a chemically and mechanically tamper proof material that is applied in cavities that are distributed in each of said at least two flexible layers that surround the electronic module in order to make the electronic module interdependent with the at least two flexible layers.
