Patent attributes
A portable dual-interface data carrier contains a metal sheet which can be provided with low technical effort and especially no ferrite material is required. The resulting portable dual-interface data carrier is more heavy than a state of the art PVC smart card and provides contact based interface on one side, whereas contactless interfaces is working from both sides of the card. One application domain of the data carrier is to provide a so-called smartcard. The present invention is furthermore directed towards a dual-interface module as well as towards a method for providing a portable dual-interface data carrier. Moreover, a data carrier is suggested comprising instructions for performing the suggested method and for manufacturing the portable dual-interface data carrier.
