ABSTRACT:
A chip card capable of selectively transmitting and receiving data via contact members or in a contactless manner (i.e., transmission coils). The chip card includes a contact block which represents and additional protection for the embedded integrated circuits and can also be used as a sensitive switching element for electronic purposes. In particular, based on the function as a switching element, the electronics can be switched on and off by the card user for purposes of the remote transmission. In addition, the contact block can be exchanged and thus assures also the contact card functions, in case the contacts are worn out.
