The invention relates to the production field of double-interface smart cards, and discloses a double-interface smart card and a production method thereof. The double-interface smart card is composed of a card base and an antenna. The middle of antenna is wound into a coil to be positioned in the edge of the card base. Two free ends of the antenna are wound into two bonding pads. Each of the bonding pads is composed of a hiding area and a contacting area. A groove is formed in the card base between the bonding pads. The two contacting areas are positioned on card base steps on two sides of the groove. The two hiding areas are positioned in the card base. The upper surfaces of the coil, the hiding areas and the contacting areas are positioned on the same plane with the upper surfaces of the card base steps. The coil is connected with a chip through the two contacting areas. Compared with the prior art, the double-interface smart card and the production method thereof have the advantages that product production cost is reduced, production process is simplified, production efficiency is improved, product rejection rate is reduced, and mass production of the double-interface smart card is realized.
