<p>A dual interface card is disclosed, which includes: a base board (1). A smart card chip (2) and an antenna (3) mutually inducting with an external card reader are set on the base board (1), in which, an energy storage component and a first induction coil (4) are also set on the base board (1); a second induction coil (5) mutually inducting the first induction coil (4) is set on the smart card chip (2); and the antenna (3) is connected with the first induction coil (4) though the energy storage component. According to the disclosed dual interface card, steps of connecting the antenna and the smart card chip can be ignored in the packaging process. On the one hand, existing contact automatic machines can be used to manufacture, and lots of manual manufacturing is reduced, thereby, the manufacturing costs are decreased and the manufacturing efficiency is improved; on the other hand, because no contact connections are needed between the antenna and the smart card chip, all unreliable factors caused by contact connections are eliminated, and the production performance is more stable.</p> |
