New applicants for a VIS Schengen visa have to travel to the nearest EU consulate to give their biometric information (10 fingerprints and a facial image), which is then entered into the system and remains valid for five years. Information is centrally stored in a database in Strasbourg (with a back-up site in Austria) allowing checks to be made at border crossing points that the person holding the biometric visa is the person who applied for it.
