## Image Quality Requirements

Below are the requirements for size and quality of document images captured by any device, which are necessary for accurate return of results by OkayID:

* **Good lighting**

  Good lighting helps to achieve better results. If the image is too dark or too bright, the document can not be processed.

* **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, cannot 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.
