SnapPass is an independent biometric auditing tool and is not affiliated with any government agency. Final photo acceptance is at the sole discretion of the issuing authority.

Why 1 in 5 Applications Get Rejected

Government automated scanners are stricter than the human eye.

Micro-Shadows

Even tiny shadows behind ears can trigger 'background homogeneity' errors.

Skin Luminance

Face brightness must fall within specific histograms to be machine-readable.

Biometric Geometry

Chin-to-crown distance must be exactly 70-80% of vertical height.

Neutral Expression

Mouths must be closed for algorithms to map biometric keypoints.

Frequently Asked Questions

Understanding compliance and processing.

General

Is this guaranteed to be accepted by the government?

No tool can legally guarantee government acceptance, as officials have subjective discretion. However, SnapPass aligns your photo with the exact technical specifications (size, background, lighting) published by agencies to strictly minimize rejection based on technical errors.

What happens if my photo is rejected?

If your SnapPass-processed photo is rejected for technical reasons, we offer a full refund upon proof of rejection. We also provide a corrected version free of charge.

Technical

Do you use AI to generate fake faces?

Absolutely not. We use computer vision solely to clean backgrounds and crop images. We never alter your facial biometrics (eyes, nose, mouth shape) as this would violate government 'alteration' policies.

Can I use a selfie?

Yes, but use the rear camera for higher resolution. Stand 1 meter away from the camera to avoid 'fish-eye' lens distortion which alters facial proportions.

Processing

Why is my background grey instead of white?

Some countries (like the UK and Canada) specifically require 'light grey' or 'cream' backgrounds, not pure white. SnapPass automatically selects the correct color code based on your selected document type.

How long do you keep my photo?

User privacy is paramount. Your original and processed images are permanently deleted from our servers after 24 hours. We do not sell or store biometric data.
