    Abstract: A dual-interface card reading device, having a main body and cover plate assembled to form an opening which accommodates insertion of a magnetic card or an IC card, one side of the opening defining a hollow slide groove to enable swiping of a magnetic card or an IC card. A magnetic head extends into the opening to read the magnetic card, and at one end of the hollow slide groove is an IC card contact interface for reading the IC card. A user can thus simultaneously swipe either type of card at an appropriate interface while achieving the effects of small size, low cost, and convenient operation.
