Abstract: Disclosed is a mobile terminal for transmitting WIFI hotspot key or certificate by using NFC, the mobile terminal including a transmission control module, a NFC module, a WIFI module and a SIM card module. The transmission control module, which connects to the NFC module, the WIFI module and the SIM card module, controls the work of the NFC module and the WIFI module. The NFC module, which connects to the transmission control module and the WIFI module respectively, obtains the WIFI hotspot key or certificate. The WIFI Module, which connects to the transmission control module and the NFC module respectively, completes WIFI network connection. The SIM card module, which connects to the transmission control module, saves user information of the mobile terminal. The mobile terminal in present invention that transmits the key or certificate by using NFC ensures certainty and security of client, thus greatly simplifies the actions of user.

Abstract: Disclosed are a method for controlling the operation of in-vehicle infotainment and device thereof, the method includes: detecting whether a passenger sits on the non-driver's seat, if the passenger sits on the non-driver's seat, running the corresponding in-vehicle infotainment to provide service; and detecting whether the passenger sitting on the non-driver's seat shifts, if the passenger sitting on the non-driver's seat shifts, closing the corresponding in-vehicle infotainment to stop providing service.
