[0086] see Figure 6 , the second embodiment of the present invention provides a method for controlling a mobile terminal, which is applied to the mobile terminal in the first embodiment, and the method includes:
[0087] Step 601: Select different channels of the first switch or the second switch of the mobile terminal by setting the general input / output GPIO port of the NFC chip of the mobile terminal to high level or low level.
[0088] see figure 1 , the first switch is a three-channel switch, and the second switch is a two-channel switch; where,
[0089] The first channel is controlled by the first control port S1 to select the first high-level port Y11 or the first low-level port Y10 to form a different first channel; the second channel is controlled by the second control port S2 to select the second high-level port Y21 or the second low-level port Y20 form different second channels; the third channel is controlled by the third control port S3 to select the third high-...

[0124] Figure 9 is a block diagram of a mobile terminal according to a third embodiment of the present invention. Figure 9 The illustrated mobile terminal 900 includes: at least one processor 901 , a memory 902 , at least one network interface 904 and other user interfaces 903 . Various components in the mobile terminal 900 are coupled together through a bus system 905 . It can be understood that the bus system 5905 is used to realize connection and communication between these components. In addition to the data bus, the bus system 905 also includes a power bus, a control bus and a status signal bus. But for clarity, in Figure 9 The various buses are denoted bus system 905 in FIG.
[0125] Wherein, the user interface 903 may include a display, a keyboard, or a pointing device (for example, a mouse, a trackball (trackball), a touch panel, or a touch screen, and the like.
[0126] It can be understood that the memory 902 in this embodiment of the present invention may be...
