发明名称 Forgery-proof structure for a memory card
摘要 A forgery-proof structure for a memory card includes primarily a letter pattern, such as a totem or a word of format, specification, size of storage capacity, or trademark logo, in a protruded shape, a concave shape, or a hollow shape which is directly molded on a casing of a memory card, upon molding the memory card body, so as to prevent a customer from confusion upon purchasing, and to reduce a possibility of copying by unworthy vendors, thereby constituting another kind of forgery-proof function.
