An electronic device includes a card interface and a processing module. The card interface is electrically connected to the processing module, and a SIM card or a memory card may be inserted into the card interface. The card interface includes N springs, where N>1; when a memory card is inserted into the card interface, the memory card is electrically connected to the processing module; and when a SIM card is inserted into the card interface, the SIM card is electrically connected to the processing module, and one metal pin of the SIM card is electrically connected to a first spring in the N springs and one spring adjacent to the first spring. The processing module is configured to determine, based on at least a level of the first spring, whether an inserted card is a SIM card or a memory card.
