  • Publication number: 20210076193
    Abstract: When terminal identification information TI of one terminal device used by a user among two or more terminal devices is newly stored in a memory of a host device together with user identification information UI (S3a), an examination part examines, in the memory of the host device, a presence or absence of terminal identification information (terminal identification information TI-p) corresponding to the user identification information UI, excluding terminal identification information TI and terminal identification information corresponding to a terminal device that is currently used by the user (S11). When the terminal identification information TI-p exists, a management part performs control to transmit predetermined instruction information together with the terminal identification information TI-p to the two or more terminal devices (S12).
