Common reasons ID verification may not pass automatically
The most frequent cause is a photo quality issue with the document image. To give your document the best chance of passing first time:
Lay the document flat on a dark or contrasting, plain surface.
Make sure all four corners are visible in the frame.
Avoid covering any part of the card with your fingers or thumb.
Minimise glare — avoid direct overhead lighting or bright windows behind you.
Ensure the image is in focus before submitting.
Other reasons verification may not pass automatically:
Your selfie does not clearly show your face.
The document type or country does not match what was selected.
Your document has expired or is outside the allowed tolerance window.
What happens if my verification is flagged for review?
If your verification cannot be completed automatically, a member of the Checkmate support team will assess it. They may be able to verify your document by sight, or they may contact you to request a clearer document or an alternative form of ID.
