The Schengen Information System (SIS)
The SIS is operational since 26 March 1995, the day the Schengen Convention was brought into force.
The SIS pursues a double objective:
- protect public safety and public order;
- apply the provisions on the free movement of individuals.
Can be registered in the SIS :
- persons wanted for arrest or extradition procedure;
- non-nationals for whom an alert has been issued for the purpose of refusing entry into the Schengen area;
- missing persons and persons who need to be placed under protection (especially minors and persons who have to be interned);
- witnesses or persons summoned to appear before judicial authorities in connection with a criminal matter;
- persons under discreet surveillance or specific checks in the context of combatting criminal acts or preventing disturbances in the public order.
As part of the so-called “third pillar”, the EU policy area that covers police and judicial cooperation in criminal matters, the SIS is now a second-generation system (SIS II).
