Summary:PROBLEM TO BE SOLVED: To prevent a user from using address information acquired from a service device which the user desires to use, to unintentionally use another service device on a network other than a network to which that service device is connected.SOLUTION: A service device 20A is caused to have NFC information including a MAC address of the service device 20A. A mobile device 10 acquires the NFC information from the service device 20A through tap operation and uses an IP address included in this information to attempt to access the service device 20A. The mobile device 10 has been connected to a network B other than a network to which the service device 20A is connected, and the access is delivered to a service device 20B having the same IP address on the network B. The mobile device 10 compares a MAC address of the service device 20B acquired by the access with the MAC address in the NFC information acquired through the tap operation, thereby recognizing that the accessed device is not the target service device 20A.SELECTED DRAWING: Figure 6 【課題】利用したいサービス機器から取得したアドレス情報を用いて、その機器が接続されているネットワークとは別のネットワーク上にある別の機器を利用してしまうことを防止する。【解決手段】サービス機器20Aに、当該サービス機器20AのMACアドレスを含むNFC情報を持たせておく。モバイル機器10がタップ操作によりサービス機器20AからNFC情報を取得し、その情報に含まれるIPアドレスを用いてサービス機器20Aにアクセスを試みる。モバイル機器10は、サービス機器20Aとは別のネットワークBに接続されており、そのアクセスはネットワークB上の、同じIPアドレスを持つサービス機器20Bに届く。モバイル機器10は、このアクセスにより取得したサービス機器20BのMACアドレスを、タップ操作で取得したNFC情報内のMACアドレスと比較することで、アクセスした機器が目的のサービス機器20A出ないことを認識する。【選択図】図6
