A digital frequency shift keying communication module is characterized in that the module comprises a central signal processing unit (MCU) and a frequency shift keying unit; the digital signal processing of a signal inputting the module can be carried out; and then, carrier frequency modulation is carried out by the frequency shift keying unit; and the signal after modulation can be communicated with any specific network communication module so as to realize the digital signal transmission of specific network. The module at least comprises an interface for data transmission. The module can carry out digital signal processing and digital signal frequency modulation for input signal. The module can be widely applied to terminal devices such as payment devices (POS machines), mobile telephones, interphones, stations, Bluetooth communication terminals and digital telephones. According to different requirements for network communication transmission, a corresponding structure such as a corresponding network transc
