Open your passport and go to the biographic page (The page with your photo and personal details - name, date of birth, passport number, etc.) Only capture this in your picture; exclude the cover above it.
Lay the passport flat on a table or another surface so the page is not bent or tilted.
Align the page straight in the frame. Avoid angled or diagonal shots.
Make sure the entire page is visible, including the MRZ (the two lines of numbers and letters at the bottom).
Avoid glare, shadows, and blur. Use good lighting and hold your camera steady.
