Method, device and system of obtaining network information using device as service credential

A method of obtaining network information using a device as a service credential, comprising the following steps, steps:

• (1) establishing a connection between a data processing apparatus and the device configured with network server information that is to be used as the service credential;
• (2) in the data processing apparatus, reading said information for connecting to a network server and executing a request of accessing a network and a remote information tele-service;
• (3) establishing a connection and an information interacting channel between the data processing apparatus and an information server;
• (4) sending a request to obtain information in the information server issued by merchant stations, user information of the device and operation content further to be sent by the data processing apparatus;
• and
• (5) feeding back requested information to the data processing apparatus through the information interacting channel by the information server according to the operation content if the request is validated, otherwise, feeding back error information and the interrupting an operation if the request is not validated;
• wherein step (2) comprises the following process:
• (2.1) the data processing apparatus supplying power directly to the device;
• (2.2) auto-run files in the device being read by the data processing apparatus;
• (2.3) a network access request of the auto-run files being executed by the data processing apparatus;
• and
• (2.4) a service request being sent to the information server which is identified in the auto-run files and a connection being established between the data processing apparatus and the information server which is identified in the auto-run files if the information server responds;
• wherein, in step (5), latest information updated or supplemented in the information server can be sent directly to the data processing apparatus after a latest connection by users, and written into a storage medium of the device to replace originals by the data processing apparatus after the validation of user information;
• or
• in step (5), the user information in the information server can be changed, or user authority adopted to be changed by a network manager after the validation of the user information and in addition, changed information fed back by the data processing apparatus is adopted to be written into the storage medium of the device to replace the originals;
• wherein, the device used as the service credential has a specific mark or a specific shape.
