  • Two-dimensional code processing method and apparatus
    Patent number: 10534946
    Abstract: A two-dimensional code generation request is received by a server from a two-dimensional code display client. Static, two-dimensional code information and a random feature value are generated by the server. The generated static, two-dimensional code information and the random feature value are sent by the server to the two-dimensional code display client to display a combinational, two-dimensional code on the two-dimensional code display client. A two-dimensional code verification request sent by a two-dimensional code scanning client is received by the server. A two-dimensional code scanning status value is sent by the server to the two-dimensional code scanning client.
    Type: Grant
