Data carrier or document carrier

A read/write station for contactless transmission with an electronic data carrier, wherein the electronic data carrier comprises;

• a first page and a second page;
• a connection axis between the first page and the second page, wherein the first page and the second page can be folded apart at the connection axis in an opened state and folded toward one another at the connection axis in a closed state;
• an electrical circuit to store the data;
• a coupling element coupled to the electrical circuit, the coupling element comprising a capacitive element to facilitate the contactless transmission between the electronic data carrier and the base station, wherein the coupling element is at least partially embedded into or integrated with each of the first and second pages, wherein the coupling element is configured to facilitate the contactless transmission with the base station essentially only in one state of the opened state and the closed state;
• wherein the capacitive element comprises:
• a first plate embedded in the first page, the first plate of the capacitive element comprising individual part-areas connected to one another;
• and
• a second plate embedded in the second page, the second plate of the capacitive element comprising additional individual part-areas connected to one another;
• wherein in the opened position the capacitive element assumes a full area on the electronic data carrier to enable access by the base station;
• wherein in the closed position the first and second plate of the capacitive element are substantially aligned to disable access by the base station;
• wherein the individual part-areas of the first and second plate of the capacitive element are arranged to provide toothing that extends beyond the connection axis;
• wherein an electrical connection between at least some of the individual part-areas of the capacitive element are configured for individual coding.

An electronic communication system comprising:

• a base station;
• and
• an electronic data carrier for contactless transmission with the base station, wherein the electronic data carrier comprises;
• a first page and a second page;
• a connection axis between the first page and the second page, wherein the first page and the second page can be folded apart at the connection axis in an opened state and folded toward one another at the connection axis in a closed state;
• an electrical circuit to store the data;
• a coupling element coupled to the electrical circuit, the coupling element comprising a capacitive element to facilitate the contactless transmission between the electronic data carrier and the base station, wherein the coupling element is at least partially embedded into or integrated with each of the first and second pages, wherein the coupling element is configured to facilitate the contactless transmission with the base station essentially only in one state of the opened state and the closed state;
• wherein the capacitive element comprises:
• a first plate embedded in the first page;
• and
• a second plate embedded in the second page;
• wherein in the opened position the capacitive element assumes a full area on the electronic data carrier to enable access by the base station;
• wherein in the closed position the first and second plate of the capacitive element are substantially aligned to disable access by the base station.
