Abstract

After a digital multi-function peripheral establishes a connection with a mobile phone once, it rejects connection establishment requests made to a wireless communication section by other devices. Moreover, after a connection is established with a mobile phone once, the digital multi-function peripheral stops sending of the address of the wireless communication section through a reader/writer. After completing the sending/receiving of data, the digital multi-function peripheral and the mobile phone delete the addresses of their partner devices stored in them, respectively, for use in sending/receiving data.
