A card connector comprises an housing defining a pair grooves and a receiving space with a first entrance opening; first and second sets of contacts retained in the insulating housing and exposed in the receiving space; a protection door moveably covering the first entrance opening for receiving a first card and defining a second entrance opening smaller than the first entrance opening therein for receiving a second card; a pivotal door associated with the protection door to moveably cover the second entrance opening; and a positioning member having a respective positioning portion exposed into the groove. When the second card is inserted in the second entrance opening, the positioning portion of the positioning member moves to one end of the corresponding groove to prevent the protection door from opening.
