Mobile banking consists of mobile phone, GSM short message center and banking system. During the operation of mobile banking, after the user sends an instruction to the bank through the menu on the SIM card, the SIM card generates a short message with a specified format according to the user's instruction and encrypts it, and then instructs the mobile phone to send a short message to the GSM network. After receiving the short message, the GSM short message system sends it to the corresponding banking system according to the corresponding application or address. The bank preprocesses the short message, and then converts the instruction into the host system format. The bank host processes the user's request and returns the result to the bank interface system, and the bank interface system converts the processing result into the short message format.
