1. A pre-form of a card-type information substrate, comprising
a frame formed around a perimeter of a base material, said material of said frame having a higher specific weight compared to the base material in the form of plastic and thus imparting increased weight to said pre-form;
a metal containing plate provided within an outline of said frame and imparting additional weight to said pre-form; and
an antenna positioned within said outline of said frame and configured to enable wireless communication;
wherein a thickness of said frame corresponds to a combined thickness of said base material and said antenna, and to a total thickness of said pre-form of said card-type information substrate;
characterized in that
said pre-form further comprises:
a first disconnecting layer covering, said frame, said base material, said metal containing plate and said antenna, said first disconnecting layer being attached to said frame and forming a first surface of said pre-form,
wherein said first disconnecting layer comprises a rigid material which does not soften or flow onto or into respective steps formed by thickness differences of the materials of said frame, said base material, said metal containing plat plate or said antenna during lamination of further components to said pre-form.
