Abstract
Provided is a method for manufacturing a radiofrequency chip card. The method comprises the steps of: forming a card body comprising a relay antenna and an insulating cover layer on at least one main face of the card, arranging a module equipped with a radiofrequency module antenna on the card body opposite the relay antenna for radiofrequency coupling; forming a metal insert in the card body, the insert extending up to the edges of the card and comprising a space permeable to the radiofrequency field opening on at least one of the two main faces of the insert and comprising the relay antenna inside and/or opposite this space. Provided also is a corresponding card produced by the method.
