Method of data transfer

摘要

A method for transferring one of a plurality of data stored in a sub-computer system (110) to a target computer system using a mobile device (100) is provided. In such a method, the mobile device (100) initiates the process by sending instructions to a central computer system (106) via a first network (108). The instructions designate a first piece of data to be transmitted as well as the target computer system to which the first piece of data is to be transmitted. According to the instructions, the central computer system (106) retrieves the designated first piece of data from the sub-computer system. The first piece of data then is transmitted from the central computer system (106) to the target computer system.
