Abstract: A method, device and terminal for binding an NFC application and an operator are disclosed in the embodiments of the present document. The method comprises: after receiving an operation command sent by an upper application program of a terminal, an NFC middleware judging whether the operation command is within an NFC service permission opened by the terminal at an operator; when determining that the operation command is within the NFC service permission opened by the terminal at the operator, sending the operation command to an NFC device; the NFC device reading original NFC data according to the information in the operation command; and after performing data processing on the original NFC data, sending the data to the upper application program.

Abstract: An implementing method for matching the frequency bands of the mobile terminals, a mobile terminal, and a mainboard thereof are disclosed. The mobile terminal involves a signal transmitting/receiving module with at least two frequency bands, a radio-frequency transmitting module, a radio-frequency receiving module and a radio-frequency front-end module. The mobile terminal further involves a first connection selection module and a second connection selection module. The implementing method for matching the frequency bands of the mobile terminals comprises the following steps. The multi frequency bands bonding pad compatibility is achieved respectively on the circuit board by the radio-frequency transmitting module, the radio-frequency receiving module and the radio-frequency front-end module.
