Abstract
A method of reading electrical information, which comprises arranging electric field-generating means having a pulse oscillator and detection means of detecting a potential in the electric field to form an electrostatic coupling space and/or a latent electrostatic coupling space where the and the detection means can sense a change in the electric field as a change of potential passing an information carrying member formed by covering an electrically conductive member having a form expressing information with an electrically nonconductive material through the electrostatic coupling space or the latent electrostatic coupling space, thereby to detect the information expressed by the form of the electrically conductive member, and information carrying member for use in the method.
