Abstract
The invention discloses a mobile terminal and a communication device thereof. An SD (Secure Digital) card and an NFC-SIM (Near field Communication-Subscriber Identity Module) card are arranged in the mobile terminal, the device comprises a master mobile terminal control chip, an NFC control chip and a switch, and the NFC control chip is connected with the switch through an SWP (Single Wire Protocol) communication interface. During near field communication of the mobile terminal through the NFC-SIM card, the master mobile terminal control chip controls the switch, so that only the NFC control chip and the NFC-SIM card are in conduction through the switch. During near field communication of the mobile terminal through the SD card, only the NFC control chip and the SD card are in conduction through the switch controlled by the master mobile terminal control chip. Since the SD card and the NFC-SIM card are integrated in one mobile terminal and can be selected according to different communication modes, the NFC card swiping services of users in two systems are facilitated, and the development of NFC applications is promoted.
