Abstract: Disclosed is a method for collecting a transportation fare using a mobile terminal. When the mobile terminal is adjacent to transportation means, a collection server issues a onetime boarding ticket which grants an authority to get on the transport means at a current location of the mobile terminal and transmits the onetime boarding ticket to the mobile terminal. A validator in the transportation means validates the onetime boarding ticket through short-range communication with the mobile terminal and transmits the validated result to the collection server. The collection server collects the transportation fare to the mobile terminal.
