The SIS is used by 31 European countries to find information about individuals and entities for the purposes of national security, border control and law enforcement since 2001. A second technical version of this system, SIS II, went live on 9 April 2013.[1] An upgraded Schengen Information System entered into operation on 7 March 2023.[2]
