Biometric photos according to ICAO standards

Biometric photos according to ICAO standards

1. why biometric photos are important: ICAO & ISO basics

ICAO documentation 9303 (machine-readable travel documents) defines the international standards for biometric photos used in passports, visas and ID cards. Among other things, it defines the format (usually 35 × 45 mm) and stipulates that the face must take up 70-80% of the height of the photo. In addition, ISO/IEC 19794-5 defines technical parameters such as resolution, lighting conditions, facial orientation, background and expression.

With software such as Photo Collect , you can collect biometric photos. When creating the photos, the user is guided through the process, which leads to good results. If you need to collect photos without software support, these tips will help you.

Important requirements for a biometric photo:

• Face centered, neutral facial expression, closed mouth
• Light, monochrome background without shadows
• No jewelry, no headgear (except for religious reasons), no reflections
• No smile, no tilted head posture
• When glasses are worn: thin frames, no reflections, eyes fully visible

2. how to take a biometrically correct photo

Camera, subject & composition

• The camera should be at eye level with the face in the center.
• The head, neck and shoulders should be fully visible.
• The distance to the camera should be chosen so that the face takes up about half of the picture.

Light & background

• Use soft, even light from the front - ideally daylight without direct sunlight.
• The background must be light and monochrome, preferably white or light gray.
• No shadows in the face or background, no other people or objects visible.

‍Posture & expression

• Neutral facial expression, mouth closed, eyes open.
• Head upright, looking straight into the camera.
• No lateral rotation or tilt.

Glasses & headwear

• It is best to remove glasses. If worn: no reflection, thin frame, eyes visible.
• Head coverings are only permitted for religious or medical reasons and must not cover the face.

Recording tips

• Ideally, have the photo taken by a second person - no selfies.
• Keep the image section straight.
• Ensure good sharpness and contrast - a clean lens works wonders!

Checklist before submission:

• Face centered and both shoulders visible?
• Are facial expressions and lighting correct?
• Uniform background without shadows?
• No shadows on your face, reflections or distracting elements?

Practical tips for HR teams

1. Include simple photo instructions with the invitation (pose, light, background).
2. Recommend a third-party photo - selfies are often distorted or misaligned.
3. Use a stool or a chair without a backrest to keep your shoulders visible.
4. Test the light on location - no windows behind the subject, no direct light from above.
5. Activate a preview so that users can check their photo immediately and retake it if necessary.
6. Specify whether and how often a faulty photo may be retaken.

3 Photo Collect: Automated conformity at the touch of a button

With Photo Collect, you can fully automate the entire capture and verification process - compliant and scalable. The background is replaced with a permissible color and the face is cropped to the correct size.

Automated photo capture - how it works

Users receive an invitation via email, SMS or QR code and upload the photo via smartphone or kiosk. The user-friendly interface supports correct alignment and image size as soon as the photo is taken.

AI-supported photo validation

Each image undergoes an automatic AI quality check: pixel size, head position, lighting and facial expression are checked. Faulty images are detected and the user is prompted to retake the picture.

Quality control & export

Photos are automatically cropped, the background removed and - if necessary - checked manually. If the photo is unsatisfactory, the user is informed of the reason and asked to submit an improved photo.

Conclusion

Taking biometrically correct photos doesn't have to be complicated or time-consuming. With the right tips - camera at eye level, even lighting, neutral facial expressions - you create the basis. Combined with a powerful platform like Photo Collect, the process is fast, secure and compliant.

Whether for ID cards, access control or web portals - Photo Collect is the leading solution for scalable, automated and standardized photo capture in the corporate environment.
