Abstract
The invention concerns a contactless smart card comprising an antenna (12) on an antenna support (10) made of fibrous material, this antenna consisting of a turn and two contacts (14 and 16) screen printed on the antenna support, a card body (32 and 34) on each side of the antenna support, and a chip (26) provided with contacts (28 and 30), connected to the antenna. This card also features a chip support (20) made of fibrous material having two conductive strips (22 and 24), screen printed on the chip support (20), and to which the contacts (28 and 30) of the chip (26) are connected, the chip support (20) being positioned on the antenna support (10) so that the conductive strips (22 and 24) come into contact with the contacts (14 and 16) of the antenna and connect with the latter, and in such a way that the chip (26) is positioned in a cavity (18), made for this purpose in the antenna support (10).
