Abstract

A smart card module (10) comprises an extended circuit substrate (12); a card-reader contact element (18) on one side of the extended circuit substrate (12) for connection to a smart card reader; an integrated circuit connection element (20) on another side of the extended circuit substrate (12) in electrical communication with the card-reader contact element (18) and to which an integrated circuit (22) is mountable; and an antenna (24) on the extended circuit substrate (12) and which is connected to the integrated circuit connection element (20) for receiving radio frequency signals from the smart card reader to energise the integrated circuit (22). A furthest perimeter edge of the said antenna (24) is spaced from a relative proximal edge of the card-reader contact element (18) by at least half a distance between the said proximal edge and a centre C1 of the card-reader contact element. This enables a larger antenna coil to be accommodated on the substrate with less overlap of the card-reader contact element, whilst also enabling a separate module to be formed for integration with a body of the smart card.

Description

technical field [0001] The invention relates to a smart card module, a smart card (such as a bank card or a SIM card) installed with the smart card module, a method for assembling the smart card module, and a method for assembling the smart card with the smart card module. Background technique [0002] As is well known, smart card modules (also called chip cards or integrated chip cards) are widely used in smart cards. A typical smart card is a dual-interface smart card that can communicate with a card reader both in a contact and contactless manner. [0003] A smart card module usually consists of a contact pad on one side of the module substrate and a chip soldered on the other side of the substrate. The chips are typically disposed in the area of ​​the contact pads and are in electrical conduction with the contact pads. An antenna is embedded in the smart card body outside the smart card module, and the antenna is electrically connected with the chip. [0004] The shap...
