  • Patent number: 11704531
    Abstract: A method for manufacturing a metal card includes: a step for forming a metal card by laminating a stack of sheets in which are stacked a plurality of sheets, centered 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 (CNC) 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
