Data carrier or document carrier

In order to further develop an electrical or electronic data carrier or document carrier ( 100 ) as well as a method of communication, in particular for the contactless transmission and/or for the contactless exchange of data and/or of energy, between at least one base station or central station, in particular at least one read/write station, and at least one electrical or electronic data carrier or document carrier ( 100 ) in such a way that data and information cannot be read from the data carrier or document carrier ( 100 ) without the agreement, knowledge and/or assistance of the user or owner of the data carrier or document carrier ( 100 ), it is proposed that the data carrier or document carrier ( 100 ) can be moved to and from between a first position (A) defined as an unfolded or opened state and a second position (B) defined as a folded or closed state, and that the data carrier or document carrier ( 100 ) is coupled to the base station or central station essentially only in the first position (A) or essentially only in the second position (B) or essentially only in a position between the first position (A) and the second position (B).
