Digital FCP Proは、災害時に家族がはぐれないための大切な情報を、スマートフォンにまとめて備えておける防災アプリです。 ■ こんな情報を登録できます ・家族の連絡先(名前・電話番号など) ・避難場所や家族の集合地点 ・非常時の持ち出し品・備蓄チェックリスト 登録した内容からはQRコードを作成できます。お子さんの防災リュックやランドセル、キーホルダーなどに付けておけば、万一はぐれてしまっても、周囲の人がすぐに家族の情報を確認し、連絡を取ることができます。 ■ 最大の特長:電波がなくても動く 一般的なアプリの多くは、情報をインターネット上のサーバーに預けて動くため、電波が届かないと使えません。Digital FCP Proは、入力した情報をスマートフォンの中に直接保存します。表示もQRコードの作成もすべて端末内で完結するため、インターネット接続を必要としません。通信が途絶える大規模災害時こそ、確実に力を発揮します。 ■ 安心のプライバシー設計 入力された情報は一切外部に送信されません。連絡先や住所などの個人情報は、すべてご本人のスマートフォンの中にのみ保存されます。運営を含め、外部の誰かが入力内容を見ることはできません。情報漏えいのリスクを、経路そのものから断つ設計です。 ■ こんな方におすすめ ・災害への備えを家族で共有しておきたい方 ・小さなお子さんやご家族の安全が気になる方 ・個人情報を外部に預けたくない方 ふだんは備えとして、いざというときは家族をつなぐ支えとして。ぜひご活用ください。
