To check your identity, there are several points to consider.
Your document must be a valid National Identity Card or Passport.
Driving licences are not accepted.
Screen captures or photographs are not accepted. You must photograph or scan the original document.
Your document must be legible, clean and free from reflections when scanned or photographed.
If your identity document is valid but not recognised, please see this article: How do I upload a photograph of my identity document?
