Embodiment Construction
[0071]The first implementation mode of the method according to the invention show in FIG. 2 is characterized in that a thick sheet 20, which incorporates or embeds a plurality of electronic units 4, is first of all formed. This thick sheet 20 defines a plurality of card bodies each including an electronic unit 4.
[0072]The thick sheet 20 can be made by any technique known to those skilled in the art, particularly using several layers laminated or bonded to each other. In a variant, at least one central layer has apertures, which house at least electronic elements 8 and 10. In another variant, electronic unit 4 is incorporated in a press where plastic layers are first of all softened sufficiently and then pressed in a controlled manner so that electronic unit 4 penetrates these layers to form its own housing. Thick sheet 20 can, in another variant, be obtained by pouring or injecting a liquid resin.
[0073]Preferably, flat surfaces 21 and 22 of thick layer 20 are opaque, and in particul...
