Abstract: The invention relates to an antenna inlay for a smart card with a contactless communication interface or a dual contact and contactless communication interface. The antenna inlay does not have a layer of plastic material, and is essentially constituted by a metal sheet comprising conductive turns delimited by zones rendered non-conductive by anodization.

Abstract: The invention relates to a portable communicating object (20) the operating mode of which is a contact or contactless mode, or a hybrid mode which is both contact and contactless, said object comprising a body (50) having external protective layers (15, 16) and an insert (40) placed between said protective layers, said insert (40) comprising a substrate (41) bearing a first electronic component (11; 60) having first connection pads (17) and further bearing at least a second electronic component taking the form of an electronic module (12) placed in a cavity (51) of the body (50), which cavity is obtained by machining, said electronic module (12) having second connection pads (18), and said insert (40) further comprising, on the one hand, interconnecting tracks (21, 22, 23, 24) intended to connect said first electronic component (11; 60) with said electronic module (12) so as to ensure electrical power is supplied thereto or data transferred therebetween, and on the other hand, connecting tracks (29) between s
