Biometric identity verification
Stop unauthorized people at the perimeterwith biometric face matching
Biometric identity verification matches live arrivals against pre-verified IDs, stopping credential sharing, and unauthorized entry.
















Workflow
Verify identity before arrival. Confirm it at the gate.
Pre-registration proves who the person is. Gate check-in confirms it's actually them standing at your perimeter.
- 01
Mobile ID check (KYC)
People upload an ID card or passport and take a selfie on their phone before arrival. 9ID confirms the face matches the photo on the ID.
- 02
Live face match at check-in
At the kiosk, a live selfie is captured and compared to their pre-verified profile. Matches pass instantly; mismatches route to security staff.
- 03
Automatic access
Once confirmed, 9ID connects directly to your physical access hardware to grant entry in real time.
Before arrival
Verify identity on mobile before arrival
-
Upload ID document
The worker takes a photo of their passport, national ID card, or driver's license. 9ID checks that the document is valid, unedited, and readable.
-
Match selfie to ID photo
The worker takes a quick selfie on their phone. 9ID compares face directly against the photo on the ID card to confirm it really belongs to them.
AT THE GATE
Instant face matching at the gate
A camera at check-in compares the worker's face against their verified registration photo before unlocking entry.
-
Person arrives at the kiosk
After arriving, the worker identifies themselves at the kiosk by QR code, badge, etc.
-
Live selfie captured
The kiosk camera captures a new live photo and compares it to the selfie from registration.
-
Match or review
A match clears check-in without interruption. A mismatch holds access and routes the case to security staff for review.
Match outcomes
Guards stay in control of edge cases
When a face match is unclear, 9ID hands the decision to your security team to investigate and decide whether to grant access.
-
Match: Instant entry
If the live face capture matches the profile on file, the person is cleared to enter your site.
-
Mismatch: Guard review
If the live face capture doesn't match, the gate stays closed and alerts guards to clear the person manually.
-
No profile: Manual check-in
When no selfie is on file yet, 9ID skips the camera check and routes the worker straight to reception for a manual check-in.
Confirm every arrival is the right person
Pair KYC identity checks with live face match at the gate, without slowing throughput or adding reception admin.
