This guide outlines essential practices for capturing and uploading ID documents and selfies, ensuring a smooth and secure digital onboarding experience. By adhering to these guidelines, users can significantly enhance the accuracy of identity verification, reducing errors and improving the overall success rate.

Best Practices for Image Capture

Selfie Capture Recommendations

For the most effective liveness checks, it's best to take a selfie directly from a mobile phone. Here's how to capture the perfect selfie for verification purposes:

  • Positioning: Face the camera head-on and ensure your face occupies 60-70% of the frame. Avoid extreme angles and poses.
  • Expressions: Keep a neutral expression. Remove dark glasses or tinted lenses, and ensure both eyes are open.
  • Lighting: To increase visibility, avoid bright backlighting and glare. Photographs should be taken under even lighting conditions.
  • Focus & Movement: Ensure the image is not blurry, as this can affect performance similarly to low resolution. If focusing issues arise, adjust your distance from the device.
  • Orientation: Maintain the device in portrait mode without rotating it.

Document Capture Guidelines

Capturing ID documents correctly is just as crucial as selfie capture. Follow these tips for the best results:

  • Positioning: The ID document should fill 60-70% of the frame, avoiding extreme angles.
  • Lighting & Focus: Similar to selfie capture, ensure the lighting is even and the image is in focus. Adjust your distance from the camera if necessary.
  • Orientation: Always take photos in portrait mode, not landscape.

File Formats and Technical Specifications

When uploading photos for verification, it's important to use compatible file formats. Here are the formats we support and their recommended uses:

  • BMP (Bitmap Image File): Best for high-quality image data, like scanned documents.
  • JPG (JPEG Image File): Ideal for photographs and ID card images, offering a good balance between quality and file size.
  • PNG (Portable Network Graphics): Perfect for images requiring high quality or transparency, such as detailed ID documents.
  • GIF (Graphics Interchange Format): Suitable for simple images with limited colors, like logos or icons.
  • PDF (Portable Document Format): Recommended for document uploads, including multi-page ID documents.

Note: Uploading photos in formats not optimized for liveness detection may reduce accuracy. If uploading a selfie, ensure it meets the minimum file requirements.


By following these guidelines, users can expect a more efficient verification process, leading to a higher success rate in user onboarding and a superior user experience. Proper image capture and adherence to technical specifications are key to the seamless integration of security measures in digital platforms.
