| 摘要 |
The present invention is electronic circuit of the microprocessor of a proximity document, comprising the microprocessor (4), the transceiver antenna (3) and the touch switch (2), characterized in that said switch (2) comprises an active graphene element, wherein the switch contacts (2) are led to the surface of the document and so electrically connected to the microprocessors (4) and the antenna (3) that touching them closes the circuit and allows communication between the microprocessor (4) and the antenna (3), while in the opposite case the circuit is opened, and the communication between the microprocessor (4) and the antenna (3) is not possible. The invention further includes the proximity document containing such an electronic circuit. |
