EU Schengen Information System (SIS)

The EU Schengen Information System (SIS) is a secure database used by European countries within the Schengen Area to share information on individuals and objects related to security and border control. It helps authorities track wanted persons, missing individuals, stolen vehicles, or documents, enhancing safety across borders. When someone is flagged in the SIS, authorities are alerted to prevent illegal activities or locate persons needing assistance. It facilitates rapid information exchange, making border checks more efficient while allowing free movement for travelers within the Schengen zone.
