SIS

The Schengen Information System (SIS) is the most widely used and largest information sharing system for security and border management in Europe. As there are no internal borders between Schengen countries in Europe, SIS compensates for border controls and is the most successful cooperation tool for border, immigration, police, customs and judicial authorities in the EU and the Schengen associated countries. Since 1995, the system has helped Europe preserve its security in the absence of internal border checks. In 2013, the second generation of SIS (SIS II) was rolled out, with additional functionalities, such as the possibility of adding fingerprints and photographs to alerts. In March 2023, SIS was renewed with new alerts, upgraded data and enhanced functionalities.
