Abstract

In a system having a central unit, a terminal control equipment and terminal devices connected through communication lines, a transaction operation by an unauthorized terminal device is prevented. Unauthorized use prevention information is registered to each of the terminal devices and the unauthorized use prevention information of the respective terminal devices is registered to the terminal control equipment. The terminal device, when it transmits transaction data to the terminal control equipment, transmits the unauthorized use prevention information of its own. The terminal control equipment compares the received unauthorized use prevention information with the registered unauthorized use prevention information of the corresponding terminal device and, if they are in a predetermined relation, permits the transaction operation.
