Patent ID: 8356756

Claim:
A chip card module comprising: a substrate having a first side and an opposite second side, where contact areas are arranged on the first side, and a first conductor structure is arranged on the second side, the first conductor structure runs from one contact region on the second side to one of another contact region on the second side and/or a second conductor structure, which is connected to the contact areas on the first side by means of a through hole in the substrate, so that the first conductor structure runs at least partly in a central region; a chip, which is arranged over the central region on the second side of the substrate, comprising connections wherein one of the connections is connected to the one contact region on the second side; a signal generator configured to generate a test signal to be applied to the connection which is connected to the one contact region on the second side, wherein the test signal is a constant voltage signal; and a signal detector configured to detect the test signal at the connection which is connected to the other contact region on the second side, wherein a difference between the test signal at the connection which is connected to the one contact region on the second side and the test signal at the connection which is connected to the other contact region on the second side indicates an attack.
