A multilayer contactless smartcard including an electronic chip embedded in the card, the chip being connected to an antenna printed on a carrier layer and two card bodies, one on each side of the carrier, each including at least one plastic layer and The antenna carrier is opaque and includes a first cut-out forming a void filled with a transparent plastic; and the plastic layers of the two card bodies each include a second cut-out forming two identical voids and the outlines of which superimpose, in order to make a transparent zone appear in the thickness of the card, forming a transparent logo in the shape of the cut-out. A process for manufacturing such a card is also disclosed. 18-. (canceled)9102220.
