The invention discloses a production method of a double-interface
smart card and a double-interface
smart card. The production method of the double-interface
smart card comprises: providing an antenna layer and an antenna, embedding the antenna on a
joint surface of the antenna layer, and embedding an antenna head and an antenna
tail of the antenna in a preset area of the antenna layer; providing a first protective layer, and embedding an isolation block on a binding face of the first protective layer; after laminating the binding face of the first protective layer to the
joint surface of the antenna layer, combining the first protective layer with the antenna layer by a laminating technology, wherein the isolation block covers the preset area, and a
melting point of the isolation block is higher than a
heating temperature of the laminating technology; separating the preset area from other areas of the antenna layer; lifting the preset area, and separating the antenna head and the antenna
tail of the antenna from the preset area; and providing a
chip, and fixing the
chip, the antenna head and the antenna
tail on the antenna layer after electrically connecting the
chip with the antenna head and the antenna tail. According to the technical scheme of the invention, efficiency of manufacturing the double-interface smart card and a qualified rate of the double-interface smart card can be improved.
