午前2時13分に返金が承認された——誰が、なぜ？POS権限と監査ログで店舗を守る

小売リスクは、割引、返金、取消、価格変更、現金調整、データ出力、権限変更を誤った人が実行することから始まります。役割、承認、PIN、監査履歴を解説します。

権限は役職ではなく職務責任に従う

Every sale, refund, cash movement, and adjustment should belong to the person who actually performed it. 小額割引、高額返金、共有端末引継ぎ、PIN失敗、一括出力、権限変更、営業時間外承認をテストします。

実際の店舗事故を考えます。Use thresholds, location limits, device restrictions, mandatory notes, evidence, alerts, delayed execution, and separation of duties. High-value refunds, cash corrections, permission changes, and bulk exports need stronger controls than low-risk actions.
