Abstract: A memory card includes a frame, an electrical circuit board inserted in the frame, a front cover securely attached on a front side of the frame and a rear cover securely attached on a rear side of the frame. The frame is defined with through slots to let male and female fasteners respectively formed around edges of the front and rear covers to extend therein. The male and female fasteners of the front cover are extended into the through slots from a front side of the frame and securely engaged with the corresponding female and male fasteners of the rear cover, which are extended into the through slots from a rear side of the frame. In such a way, the memory card is easily assembled without special equipment, and the production efficiency of the memory card is greatly reduced.
