specific Embodiment 1
[0042] The information server communicates through the TCP / IP protocol, and the POS terminal communicates through the wireless network. The POS terminal generates transaction data, converts the wireless network into TCP / IP protocol through the communication converter, and sends the transaction data to the information server. Computer and mobile phone. Since the information server computer communicates through the TCP / IP communication protocol, and the mobile phone communicates through a wireless network, when the information server communicates with the computer and the mobile phone through a communication converter, the information server directly sends synchronization data to the computer. In addition, the information server converts the TCP / IP protocol into a wireless network mode through a communication converter, and sends synchronous data to the mobile phone. Therefore, both the computer and the mobile phone can receive the synchronized data.
specific Embodiment 2
[0043] The information server communicates through the TCP / IP protocol, the mobile phone communicates through the wireless network, and the POS terminal communicates through the dial-up of the telephone line. The POS terminal converts the dialing mode of the telephone line into the TCP / IP protocol through the communication converter, and sends the transaction data to the information server. The mobile phone converts the wireless network mode into TCP / IP protocol through the communication converter, and sends the data synchronization request to the information server. The information server synchronizes the information of the POS terminal and the mobile terminal according to the received data synchronization request, and converts the TCP / IP protocol into a wireless network mode through the communication converter, and sends the synchronous data to the mobile phone.
