A method for manufacturing a metal card according to an embodiment of the present invention comprises: a step for forming a metal card by laminating a stack of sheets in which are stacked a plurality of sheets, centred on a metal sheet, including adhesive sheets having the same size as the metal sheet; an upper inlay sheet having a first antenna; and a lower inlay sheet having a second antenna; a step for forming a COB accommodation space, which can accommodate a COB, by milling a certain area of the metal card using computerized numerical control machining; a step for forming a through-hole, which exposes the first antenna and the second antenna, by milling a COB contact point region of the COB accommodation space down to the lower inlay sheet; a step for electrically connecting the first antenna and the second antenna by dispensing a conductive elastic liquid into the through-hole; and a step for bidirectionally connecting the first antenna and the second antenna to the COB by attaching the COB within the COB accommodation space so that the COB contact point is connected by the conductive elastic liquid.
Description
technical field [0001] The invention relates to a metal card and a method for manufacturing the metal card, and more particularly, the invention relates to a metal card capable of two-way communication and a method for manufacturing the same. Background technique [0002] In general, credit cards are used instead of cash, and recently, a smart card with an IC chip capable of storing large-capacity information has been developed, which can be actively used not only for payment but also as various membership cards. In this smart card market, special cards using various materials are developed. In particular, for VIP customers, we develop credit cards with different metal materials, and metal cards realize high-grade credit cards with metallic luster and provide them to special customers. [0003] However, the existing metal cards have difficulty in operating the antenna when performing non-contact communication with the reader due to the characteristics of metal, and there ar...
