An automatic package process for a card comprises stamping a metal belt to form two shells without leaving from the metal belt, injection molding two plastic frames onto the metal shells, respectively, and combining the plastic frames together to form a case. A package for a small card comprises two metal shells each having a thickness not larger than 0.15 mm, several stakes thereon and an inner surface coated with an insulator film thereon, and two plastic frames having a thickness not larger than 0.7 and 1.4 mm, respectively, injection molded onto the metal shells and embedding the stakes thereon, wherein the plastic frames are combined together by a glue or sonic welding.
