<p>The computer card is made of plastic and includes a hollow circular groove (2) closed by a cover. A winding lies in the groove forming an aerial for the transmission and reception of information to be communicated from a integrated circuit micro-chip (5). The card also includes a second integrated circuit micro-chip (6) with a programmable memory. The two chips are assembled side by side on a printed circuit (7) formed with several conductive layers formed from thin films of copper separated by spacers. The whole circuit assembly is lodged within a further hollow formed within the body of the plastic card. <IMAGE></p> |
