Abstract
Embodiments of this application provide a data transmission method, a multi-function card, and an electronic device. The multi-function card may work as a SIM card or a memory card by using electrical contacts through time division multiplexing. Data is transmitted between the multi-function card and a processor in the electronic device, so that a function of subscriber identity identification can be implemented, and a storage capacity of the electronic device can be expanded. Storage space expanded in the electronic device may be used to store a picture, audio, a video, and an application program. The data transmission method and the multi-function card provided in embodiments of this application may be used to save physical space in the electronic device. This is conducive to lightening and thinning of the electronic device.
