Abstract
A method for producing a contactless card having a support for the functional elements of the card. The support is provided with lower and upper covering layers, and the functional elements borne thereon are formed by means of extrusion, directly in contact with the support.
Claims14
A method of manufacturing integrated circuit media of the contactless type that has functional elements comprising an electronic chip connected to a winding that functions as an antenna, and a body comprising a covering layer on at least one side of said functional elements, said method comprising the steps of providing said functional elements on a support sheet, and extruding said covering layer immediately in contact with said support sheet.
(canceled)
An integrated circuit medium of the contactless type, having a central sheet for supporting functional elements, and bottom and top layers, wherein said support sheet has at least one opening through which the bottom and top layers communicate, the material of the bottom and top layers having, with the material situated in said opening, at least a homogeneous molecular continuity constituting one and the same material, said bottom and top layers being obtained by extrusion.
