FIELD: encoding.
SUBSTANCE: group of inventions discloses means for exchanging information between a mobile terminal and internal servers. An information exchange device based on a barcode image is proposed, containing: a mobile terminal and two internal servers, wherein at least one internal server is made with the possibility to exchange information with the mobile terminal; the specified at least two internal servers include the first internal server and a set of second internal servers connected over a network, while the first internal server is made with the possibility to analyze encoding information corresponding to the barcode image received by the mobile terminal to determine, whether the barcode image is generated in accordance with an encoding rule, and then, the second server provides a service based on encoding information.
EFFECT: simplification and acceleration of the possibility to scan the barcode due to the possibility of the server to analyze encoding information corresponding to the barcode image.
