A card socket configured for placing a subscriber identification module (SIM) or a memory card includes a first interface, where the first interface is coupled to the SIM or the memory card through a switch. The first interface is further coupled to a first terminal of the switch. A SIM system is coupled to a second terminal of the switch. A memory card system is coupled to a third terminal of the switch. A detection circuit is configured to detect that a card placed in the terminal device is a SIM or a memory card. A control circuit controls the first terminal of the switch to couple to the second terminal of the switch or controls the first terminal of the switch to connect to the third terminal of the switch, based on a detection result of the detection circuit.
