Abstract
Disclosed is a method for the manufacture of a contact-free card comprising an antenna embedded in a card body and connected, by its connection terminals, to the contact zones of an electronic module of the card body as well as a card obtained by such a method. The method comprises depositing a plastic sheet in a cavity of a mold; dispensing liquid plastic material into the cavity; and distributing the material on the surface of the sheet so that it is guided by the antenna in order to form a layer of the card body. The disclosed method can be applied to cards that are exclusively contact-free cards and to combined cards designed for operations such as remote cash operations.
