What your customer sees
Verified in about two minutes, on their own phone
No app to install: the check runs in the phone's browser. After agreeing to the check, your customer follows six simple steps.
Screens from the live demo. Personal details are blurred.
Step 1
Scan your ID
Choose your document type, then place it on a flat, plain surface in good light. Fit all four corners inside the frame and tap Capture.
Tip: Avoid glare and shadows on the card.
Step 2
Fit your face in the oval
Hold your phone at eye level and follow the on-screen prompts, such as "Move closer".
Tip: Glasses are fine. Remove hats and face coverings.
Step 3
Hold still while colours flash
The screen flashes a short sequence of colours on your face. This proves a real person is present, not a photo or a screen.
Tip: Keep your face inside the oval until it finishes.
Step 4
Follow the prompts
You may be asked to blink or make a simple movement. This confirms you are taking part right now.
Tip: Look at the screen and do what the prompt shows.
Step 5
Wait a few seconds
AttestID reads your document, confirms liveness and matches your face to your ID photo.
Tip: Keep the page open while it completes.
Step 6
Get your result
You see the outcome straight away, and the business you are signing up with receives it automatically.

How it works
Four steps, one API call
The customer completes capture on your app or ours; you get a single decision back.
Step 1
Document capture and OCR
The customer photographs a national ID, passport, or driver's licence; AttestID extracts and validates the printed fields against the document.
Step 2
Liveness detection
A selfie is matched against the document photo and checked for liveness, catching printed photos and screen replays.
Step 3
Fraud and duplicate detection
Every submission is screened against prior verifications across AttestID's whole customer base for identity reuse and cross-company fraud.
Step 4
Verification decision
A pass, fail, or needs-review decision returns via API in seconds, with the underlying evidence retained for audit.
