The second version of the Schengen Information System, SIS II, has been in operation since 9 April 2013 making it possible to store biometric data (photographs and fingerprints) as well. For this purpose, the corresponding articles of the CISA were replaced by two newly established legal bases for SIS II (EU Council Regulation and EU Council Decision).
SIS II contains for example data on non-EU nationals for whom an alert has been issued for the purposes of refusing entry (e.g. for having committed an offence). Each Schengen state has access to this data in the form of a national information system (NSIS). Germany's NSIS is managed at the Federal Criminal Police Office, which regularly transmits the part of the data on refusals of entry to the Federal Office of Administration. Authorities fulfilling tasks with respect to foreigners legislation can access these data, which are operated as a separate register on the register platform at Directorate-General S, when querying the Central Register of Foreigners.
