Method for the manufacture of contact-free cards
First Claim
1. 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, wherein said method comprises the following steps, according to which:
- the antenna is placed in a cavity of a mold;
thena liquid plastic material is dispensed into the cavity; and
thenthe liquid plastic material is distributed within said cavity so that it is guided by the antenna to form a first layer of the card body which does not cover the connection terminals of the antenna.

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.

12. A method for the manufacture of a contact free card, comprising:
-
providing a mold having a cavity formed therein;
thenplacing an antenna in the cavity, the antenna having connection terminals;
thendispensing a liquid plastic material into the cavity;
thendistributing the liquid plastic material, while using the antenna to guide material flow through the cavity, to form a first layer of a card body that does not cover the connection terminals of the antenna; and
thenconnecting contact zones of an electronic module to the connection terminals of the antenna. - View Dependent Claims (13, 14, 15, 16, 17)

18. A contact-free card comprising:
-
a plastic sheet; a first distinct plastic layer disposed on top of said plastic sheet; an antenna imbedded in said first plastic layer and having connection terminals on an upper surface thereof, wherein said first plastic layer and said antenna are of substantially equal average thickness so that said first plastic layer does not cover said connection terminals and wherein said first plastic layer is formed by placing the antenna in a cavity of a mold dispensing a liquid plastic material into the cavity, and then distributing the liquid plastic material while using the antenna to guide material flow through the cavity; a second distinct plastic layer disposed on top of said first plastic layer; and an electronic module imbedded in said second plastic layer and having connection zones which extend downwardly from said plastic layer and into electrical contact with said connection terminals of said antenna.

19. A method for the manufacture of a contact free card, comprising:
-
providing a mold having a cavity formed therein;
thenplacing an antenna in the cavity, the antenna having connection terminals;
thendispensing a liquid plastic material into the cavity under a pressure lower than 100 kg/cm2 ;
thendistributing the liquid plastic material, while using the antenna to guide material flow through the cavity, to form a first layer of a card body. - View Dependent Claims (20, 21, 22)
