What is the Schengen Information System (SIS)?
The Schengen Information System (SIS) was created to protect the security of the member states and prevent criminal activity. The purpose of the SIS is to guarantee public order, security and free movement of people in the Schengen Area. It makes it possible for the police and customs officers in the Schengen countries to quickly exchange information.
A Schengen visa is refused if the applicant is entered in the SIS list of alerts. A visa is also refused if the person is entered in the list by another country even if the person is not applying for the visa to enter the territory of that particular country. People from countries whose citizens do not need a visa to enter the Schengen Area, but who are entered in the SIS list of alerts may also be refused entry to the Schengen Area.
The following are entered in the SIS:
1. lost, stolen or misappropriated items and missing or wanted persons;
2. foreign nationals for whom entry is prohibited;
3. persons who are missing or need temporary protection (primarily minors and persons with restricted active legal capacity);
4. witnesses and other persons who are obliged to appear at court in criminal proceedings;
5. persons under covert surveillance or persons having to be subject to special checks in relation to the fight against crime or prevention of unrest.
The longest possible term for storing the entered data is 10 years.
The following data may not be entered in the SIS:
2. political views;
3. data describing religious or other convictions;
4. medical data;
5. data about a person's sex life.
