Abstract

Improvements in the construction of coded data carrier cards of the type used to identify the true holder thereof characterized in that said cards comprise a body of insulating material, and a conductor scheme located within said body of insulating material to produce areas of capacitance maximum and minimum preselected in said body, when a first and a second sensor plates are placed on opposite sides of the card, said conductor scheme comprising a first series of conductor members, each of which has a first and a second portion that they extend in different planes separated by the insulating material, each one of said first and second portions being joined together by a central portion which is in a plane normal to those in which said first and second portions extend, in virtue of of which a maximum area of capacit is defined when the said first and second detector plates are placed relatively close to the first and second portions respectively, compared to a minimum defined capacitance area when said first and second detector plates are placed relatively far from said first and second portions, respectively .
