Abstract: An integrative memory card adapter capable of accommodating a compact flash card, a multi-media card, a digital card and a smart media card. By positioning contact pins and entrance slots in various locations on the memory card adapter according to the specifications and input/output contact positions of various memory cards, all four types of memory card are accommodated. The memory cards can be accommodated because the input/output contact points of each memory card are in contact with corresponding contact pins inside the slots. The contact pins are in turn wired to a printed circuit board with external connection.
