Claim 11:
12. A device utilizing barcode images for implementing communication includes:
a wearable part, a mobile terminal and at least two backend servers, the mobile terminal having a wireless connection with at the least two backend servers by using a wireless network, wherein:
the first backend server includes:
a first processor:
a first memory operably connected to the first processor and including processor executable code that when executed by the first processor performs steps of:
generating coding information corresponding to service information and generating a barcode image corresponding to the coding information;
receiving registration information from the mobile terminal and sending a registration success message to the mobile terminal;
completing user registration, and storing user registration information to a database;
the second backend server includes:
a second sending/receiving unit, used for receiving a service providing request message from the mobile terminal and providing a service to the mobile terminal;
the wearable part includes:
a camera, used for taking a picture of the barcode image;
a decoder, used for decoding the taken barcode image to obtain coding information;
a third sending unit, used for sending the taken barcode image to the mobile terminal;
the mobile terminal includes:
a fourth sending/receiving unit, configure to, when the barcode image is generated according to a preset coding rule and a parameter derived from parsing the coding information is imported into client software that is installed in the mobile terminal and matches the preset coding rule, send the service providing request message to the second backend server and receiving the service from the second backend server;
an input unit, used for inputting information required by the first backend server and the second backend server;
and a display unit, used for displaying information required by the first backend server and the second backend server.
