    Abstract: A smart card module has an elongated circuit substrate; a card-reader contact element on one side of the substrate for connection to a smart card reader; an integrated circuit connection element on another side of the substrate connected to the card-reader contact element and to which an integrated circuit is mountable; and an antenna on the substrate connected to the integrated circuit connection element for receiving radio frequency signals from the smart card reader. A furthest perimeter edge of the antenna is spaced from a proximal edge of the card-reader contact element by at least half a distance between the proximal edge and a center C1 of the card-reader contact element. Thus a larger antenna coil can be accommodated on the substrate with less overlap of the card-reader contact element, whilst also enabling a separate module to be integrated with the smart card.
