Embodiment Construction
[0051] figure 1 It is a structural diagram of a security information interaction system according to an embodiment of the present invention. Such as figure 1 As shown, the security information interaction system disclosed in the present invention includes a user terminal 1 , a protocol conversion gateway 2 , a terminal access server 5 , and a main information processing server 6 . The user terminal 1 is used to obtain security information data through a card reader and user input, and transmit the security information data to the protocol conversion gateway 2 in FSK mode. The protocol conversion gateway 2 is used to analyze the received security information data in the form of FSK, convert the analyzed security information data into TCP / IP packets, and convert the TCP / IP packets Send to the terminal access server 5. The terminal access server 5 is configured to parse out the security information data from the received TCP / IP message, and transmit the parsed security informa...
