HAZARD Busterは、スマートフォンに内蔵されたGPS(全地球測位システム)と世界地図を利用して、世界各地にいる出張者・駐在員の現在地情報を、地図上で一元的に表示・確認ができるサービスです。日本からの出張者が多い中国では、グーグルの使用が規制されているため、中国では百度マップを利用することで、世界中で利用いただけます。  また、出張者・駐在員はHAZARD Busterの報告機能を利用できます。例えば、テロや災害等の緊急時には出張者・駐在員が「安否確認」報告を送信することにより、管理者からも迅速で簡単に安否確認できます。  さらに、チャット機能、掲示板機能、特定のエリア内にいる出張者・駐在員に注意喚起などのメッセージを流せる機能も取り揃えています。  これまで、有事の際の出張者・駐在員の安否確認には、渡航情報と照らし合わせたり、現地法人と連絡を取り合ったり、アナログで対応することが多く、時間がかかっていましたが、HAZARD Busterでは、簡単に位置情報を確認でき、様々な手段で連絡が取り合えるように、新たな安否確認のニーズに対応しました。 本アプリケーションをご利用頂くには、ジョルダン株式会社が提供するHAZARD Busterのご契約いただく必要があります。 「暖かいヒント」 - Hazard Busterにて定期的に位置情報取得を有効にしていると、アプリに切り替え、バックグラウンドでアプリを実行し続ける事も出来ますが、アプリの消費電力が以前よりも多く、スマホのバッテリー寿命に影響を与えます - Hazard Busterにて(iOS版)最低バージョンがiOS11.4以上のサポートとなります - 位置情報がバックグラウンドでアプリを実行し続けると、スマホのバッテリー寿命に影響を与えます
