contactless multi-layer smart card, and process for manufacturing a contactless smart card

摘要

1/1 Summary “Multilayer contactless smart card and process for manufacturing a contactless smart card” The invention relates to a multilayer contactless smart card (10 ) comprising an electronic chip embedded or embedded in the card, the chip being connected to an antenna (22) printed on a carrier layer (20), and each of the two card bodies, one on either side. said support consisting of at least one layer of plastics material (40 and 60). According to the main features of the invention, the antenna holder is opaque and comprises a first cut-out forming a void (23) filled with a transparent plastic material; and each of the layers of plastic material from the two bodies of the card comprises a second cutout forming two identical voids (43 and 63) whose edges overlap to reveal a transparent area in the thickness of the card. , forming a transparent logo in the form of clipping. The invention also refers to the method for the production of such a card.
