The present invention offers a read only card identification system, utilizing capacitive detector circuit as the identification apparatus to execute the function of a functional code. The system consists a bottom layer (300), which is a capacitive detector circuit board with n sensor terminals to detect the functional code of a card; A top layer (400) with n sensor plates (103) and a ground plate (402), is put on the top of the bottom layer (300), the sensor plates (103) and ground plate (402) are electrically connected with the sensor terminals (303) and the ground terminal of the bottom layer (300) respectively; A card (104), having a predetermined conductive pattern code plating inside, is used to put on the top of the top layer (400) for identification; A function executing apparatus, executes the function corresponding to the functional code. |
