FIELD: data transmission.
SUBSTANCE: invention relates to information exchange tools. The wearable part for information exchange based on a barcode image is comprised of an imaging unit configured to receive a barcode image; and a sending unit configured to send the received barcode image to the mobile terminal; wherein the mobile terminal communicates with at least two background servers interconnected via a network and provides different types of services; by means of identifying and converting the barcode image, operating instructions are generated, wherein said instructions are directed to the background server so as to direct the background server to a predetermined business logic and related parameters, so that the background servers process the transaction in accordance with a predetermined rule and provide services to the mobile terminal based on the barcode image.
EFFECT: technical result is increased efficiency of information exchange with servers for receiving services from servers.
