Abstract
The invention concerns a method for making smart cards capable of operating with or without contact called mixed cards and contactless smart cards. In order to avoid the risk of deteriorating the antenna the method consists in producing an antenna comprising at least two turns, on a support sheet, said antenna having its turns located outside the connecting pads, and in providing an insulating bridge so as to connect each of the antenna ends to a connection pad respectively.
Claims12
An integrated circuit card, comprising:
- an antenna winding with at least two turns and a pair of ends or pads respectively defining two connection points and being located on a support sheet on a common side of said turns such that no turns of the antenna winding are disposed between said pair of ends or pads, a link that crosses said turns to connect a terminating one of said turns to one of said connection points, with said link being insulated from said turns to avoid a short circuit.
An integrated circuit card, comprising:
- a support sheet comprising an antenna winding mounted on the support sheet, the antenna winding having at least two turns and two connection pads or ends,
- wherein the two connection pads or ends are both disposed on a common side of said antenna winding, an insulating material covers a zone across said antenna winding, and a conductive element is laid upon said insulating material to connect an end of said winding on a side opposite said common side to one of said connection pads or ends.
