How can I confirm if my biometrics were taken when my previous Schengen visa was issued?

Once finger scans are taken and stored in VIS, they can be re-used for further visa applications over a 5-year period.

To confirm that your biometric information is on file, you can check your most recent Schengen visa. If VIS is stated on the Remarks line, then your biometrics data is on file for 5 years past the expiry date of that original visa.
