Abstract
When a user B presses a button, a display unit generates a pseudo-random number based on a clock time of a first clock and a unique ID of the display unit, then displays the generated pseudo-random number on a liquid crystal display. Upon receiving a signal from a mobile telephone, a telephone transfer server receives information generated by operating the mobile telephone. Upon receiving the information, the telephone transfer server generates a pseudo-random number based on a clock time of a second clock and the unique ID of the display unit stored in advance, and determines whether or not the pseudo-random number so generated matches the pseudo-random number in the received information. In the affirmative case, the telephone transfer server connects the mobile telephone to a fixed telephone.
