FIELD: electricity.
SUBSTANCE: invention relates to communication tools. The bar code imaging-based device for exchanging data is comprised of: a mobile terminal configured to retrieve an image of a bar code; no fewer than two background servers; the first of the background servers is configured to parse coding information that corresponds with the image of the bar code retrieved by the mobile terminal, distinguish coding information that corresponds with the image of the bar code, and determine whether the coding rule for the image of the bar code corresponds with the coding rule for the first background server to determine the possibility of the mobile terminal to acquire services from the second background sever, and if the coding rule for the image of the bar code corresponds with the coding rule for the first background server and the mobile terminal sends out a request for the services, then the second background server provides the corresponding services based on the coding information that corresponds with the image of the bar code.
EFFECT: technical result of the invention is increased efficiency of data exchange with the servers for receiving service from the servers.
