DUAL-INTERFACE SMART CARD
First Claim
1. A smart card, comprising:
- (a) a card body, the card body comprising an antenna,(b) an integrated circuit (IC) module coupled to the card body, the IC module comprising an IC chip and a contact pad electrically coupled to the IC chip, and(c) a first conductive element for electrically coupling the IC module to the antenna, the first conductive element being permanently conductively coupled to one of the antenna and the contact pad, the first conductive element having a first end that is adapted to resiliently electrically contact the other of the antenna and the contact pad, the first conductive element being adapted to flex to the extent necessary to maintain electrical contact with the other of the antenna and the contact pad upon movement of the IC module relative to the card body.

Abstract
A dual-interface smart card comprises an integrated circuit (IC) module coupled to a plastic card body. The IC module includes multiple contact pads that are electrically coupled to corresponding sections of a radio frequency (RF) antenna incorporated into the card body. Each contact pad is electrically connected to the RF antenna by a pair of opposing conductive elements, with one conductive element being permanently welded to the contact pad and the other permanently welded to the antenna. Each conductive element is in the form of a multi-stranded braided wire that is frayed at each end, the frayed ends of opposing conductive elements entangling each other upon assembly to establish redundant, resilient electrical connection between the contact pad and the antenna. To further increase the reliability of the connection between each contact pad and the antenna, the entangled frayed ends of opposing conductive elements are encapsulated within a conductive filler material.
