1. A A prelaminated body for a smart card having at least one lead-frame integrated into the prelaminated body, the at least one lead-frame comprising:
a planar lead-frame body portion;
at least one contact pad having a planar contact portion; and
at least one bridging portion of an annular ring shape coupled with the planar lead-frame body portion and extending away from the planar lead-frame body portion towards the at least one contact pad and between the planar contact portion and the planar lead-frame body portion,
wherein the at least one bridging portion extends out of a plane defined by at least one of the planar lead-frame body portion and the planar contact portion and at least partially in parallel to a substantially normal direction of the planar contact portion,
wherein the at least one bridging portion of the at least one lead-frame is at least partially removed such that the planar lead-frame body portion of the at least one lead-frame and the planar contact portion of the at least one lead-frame are electrically disconnected.
