Inlet sheet for a book-like electronic identification document

An inlay sheet configured to be used in a book-like identification document, the inlay sheet comprising:

• a first hinge layer comprising polycarbonate;
• a second hinge layer comprising a flexible material different to polycarbonate, the second hinge layer being attached to the first hinge layer;
• a first datapage layer;
• and
• a second datapage layer;
• wherein the first datapage layer and the second datapage layer are attached to the first hinge layer and the second hinge layer, such that the first and second hinge layers are positioned between the first and second datapage layers forming a datapage section having a datapage thickness (tdp), the first and second datapage layers forming a datapage inner front edge;
• wherein the first and second hinge layers extend beyond the datapage inner front edge such that a hinge section is formed having a hinge thickness (th) smaller than the datapage thickness (tdp).

A method for manufacturing an inlay sheet, the method comprising:

• providing a first hinge layer comprising polycarbonate;
• providing a second hinge layer comprising a flexible material different to polycarbonate;
• providing a first datapage layer forming a part of a datapage section;
• providing a second datapage layer forming another part of the datapage section;
• and
• bonding together the first and second hinge layers and the first and second datapage layers such that the first and second hinge layers are positioned between the first and second datapage layers and the first and second hinge layers extend beyond an inner front edge of the datapage section, forming a hinge section having a hinge section thickness (th) smaller than a datapage section thickness (tdp).
