Abstract: The present application discloses a method, an electronic device and a system for realizing functions through a NFC tag, and relates to the field of electronic devices. The present application solves the problem of low interaction efficiency due to the fact that multiple functions cannot be realized at the same time by touching the NFC tag on a device once. After a user touches an NFC tag on other electronic devices with an NFC-enabled electronic device, multiple functions can be realized at the same time. For example, after the user holds a mobile phone to touch an NFC tag on a television, the mobile phone can not only establish a wireless connection with the television, but also can synchronize the video being played on the mobile phone to the television for playing. For another example, after the user holds the mobile phone to touch an NFC tag on a loudspeaker box 1, the mobile phone can not only establish a wireless connection with the loudspeaker box 1, and when it is determined that the mobile phone also establishes a wireless connection with a loudspeaker box 2, the mobile phone can also synchronize data of one channel in the audio being played on the mobile phone to the loudspeaker box 1, and synchronize data of the other channel to the loudspeaker box 2, so that the two loudspeaker boxes achieve the stereo audio output.
