Abstract
A communication module of a communication terminal is configured not to output to a control module, service information provided from a second server whose server ID is not registered in a first server. The communication module is configured to receive an authentication code from the first server, and to transmit ID information and terminal identification information to the second server. When the terminal identification information received from the communication module matches the terminal identification information received from the first server, the second server is configured to reply the authentication code and the service information to the communication module. When the authentication code received from the first server matches the authentication code received from the second server, the communication module is configured to output the service information to the control module.
