wherein the printed surface is printed with a number or an address of an index for referring to a number of the mobile terminal for receiving an incoming call coded as a dot pattern,
wherein the control device decodes the dot pattern of the printed surface into the number of the mobile terminal for receiving an incoming call or the address by optically reading the dot patter, calls or sends an e-mail to the mobile terminal for receiving an incoming call, and accepts PIN code input from the mobile terminal for receiving an incoming call.</p> |
