How to get better result for OCR KTP CHECK?

To increase the pass rate in OCR it needs to optimize both image quality and data clarity. Here are some best practices

1. Capture a High-Quality Image

• Use a high-resolution camera (smartphone camera is usually fine).
• Make sure the image is sharp, not blurry.
• Hold your hand steady or place the KTP on a flat surface.

2.  Ensure Good Lighting

• Use even lighting — no shadows or glare on the KTP.
• Avoid overhead lights that cause reflections on the laminated surface.
• Use natural daylight or diffuse lighting for best results.

3. Proper Positioning

• Align the KTP straight (not tilted or angled).
• Make sure all edges and corners are visible in the frame.
• Avoid cropping — the full ID must be shown.

4. Clean the KTP Surface

• If your KTP is smudged, scratched, or dirty, gently clean it first.
• Remove any plastic covers or holders that cause reflections.

5. Use the Recommended App or SDK

• If you’re using a specific service or app (e.g., e-KYC or fintech apps), use the official app that’s optimized for OCR.
• Some apps allow manual adjustments of the cropped region — use them if needed.

6. Make Sure the KTP Is Valid and Clear

• Text should be:
  • Not faded or worn out.
  • Legible, especially the NIK, name, and address.
• Newer e-KTPs generally work better than older, damaged ones.

7. Avoid Image Compression

• Don’t send heavily compressed images (like via WhatsApp).
• Upload the original photo directly from the camera.

8. Check Key Fields After OCR

• Most OCR failures are due to:
  • NIK not being detected or misread.
  • Misreading letters like “O” vs “0”, or “I” vs “1”.
• Use OCR systems that let you manually verify or edit fields
