Good Lighting
Good lighting helps to achieve better results. If the image is too dark or too bright, the
document might not be processed successfully.
Avoid Reflections
Glares and reflections interfere with processing and reduce data extraction accuracy.
We recommend not to use the flash of your mobile device when capturing document
images.
Focus and Sharpness
Make sure the image is clear and there are no blurred areas.
Angle
The tilt angle of the document should not exceed 10 degrees in any direction (horizontal
or vertical).
Margins (too small)
Make sure there is minimal space around the document. It is recommended that the
document takes up 70-80% of the image.
Margins (too big)
Make sure the space around the document does not take up more than 20-30% of the
image. It is recommended that the document takes up 70-80% of the image.
Contrast
The document should be in clear contrast to the background. A light-colored document
on a light background, as well as a dark-colored document on a dark background, might
not be recognized.
Resolution of the image
To achieve a good quality of recognition of identification documents, we recommend that
you provide images captured by a camera with a resolution of at least Full HD
(1920×1080) and autofocus.
Extraneous objects
Make sure your hands or other objects do not cover document data.
