Verify a letter

Check that a visa support letter, event confirmation or certificate from Chemsol is genuine.

Printed at the foot of the letter, next to the QR code. Scanning the code opens the result directly.

The check shows what the letter itself states: who it was issued to, for which event, when it was issued and until when it is valid. It never shows passport numbers or dates of birth.
