The Visa Information System (VIS) allows Schengen States to exchange visa data. It consists of a central IT system and of a communication infrastructure that links this central system to national systems. VIS connects consulates in non-EU countries and all external border crossing points of Schengen States. It processes data and decisions relating to applications for short-stay visas to visit, or to transit through, the Schengen Area. The system can perform biometric matching, primarily of fingerprints, for identification and verification purposes.
Individuals have the right to be informed about the processing of their personal data in the VIS system. On the basis of this right, which is guaranteed in the Schengen acquis, an individual can have wrong information about him-/herself corrected and wrongly registered information deleted. Data protection authorities in the Schengen States inform how to request access to information in each country. If an access request is denied or not answered, the individual in question can file a complaint with the respective data protection authority. The Icelandic Data Protection Authority supervises the compliance with the Schengen acquis on data protection in Iceland.
Further information on the VIS system is available on the website of the European Commission.
