Claim 9:
10. 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 the at 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 third sending unit, used for sending the taken barcode image to the mobile terminal;
the mobile terminal includes:
a decoder, used for decoding the taken barcode image to obtain the coding information;
a fourth sending/receiving unit, configured 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 a second 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.
