Web · Android · REST API
One verification engine, available on every platform you use.
How it works
One flow, four checks
The exact flow below is what you can try yourself in the live demo.
Liveness detection
The camera confirms a live human is present using natural blinks, head movement, texture analysis and screen-reflection detection — with three configurable security levels.
Document scan
AI-powered OCR reads passports, national IDs and driver's licences from any country, in any language, and standardises the extracted fields.
Face match
The live face is biometrically compared with the photo on the document and given a confidence score against a configurable threshold.
Fingerprint capture
Optional touchless capture of four fingerprints using the device camera, with support for scanned fingerprint images at 500+ DPI.
Capabilities
Everything a verification flow needs
Each capability below is live in the product today — try any of them in the demo.
Real-time face tracking
Facial movements are tracked frame by frame during verification to prevent spoofing.
Advanced blink detection
Natural blinking confirms liveness, validated against natural blink-timing patterns.
Anti-spoofing analysis
Texture analysis and screen-reflection detection distinguish live faces from photos, videos and screens.
Document OCR
Extracts and standardises identity data from documents in any language into clean, structured fields.
Biometric face matching
Compares the live capture with the document photo in real time, with configurable confidence thresholds.
Touchless fingerprints
Four-finger contactless fingerprint capture using the phone camera — no dedicated hardware required.
Face login
Sub-second face authentication for kiosks, telemedicine equipment and returning users.
REST API
Every step of the flow is exposed as an API endpoint for web, mobile and desktop integrations.
Privacy by design
Self-hosted processing, encrypted storage of sensitive data, and comprehensive audit logging.
Under the hood
Engineered to be examined
Serious buyers ask how it works. Here is the honest answer — and you can verify every claim in the live demo.
Challenge-based liveness
Liveness is established through multiple independent challenges — blink count and timing, head movement, face-size consistency, texture variance and screen-reflection analysis — not a single check.
Security profiles you control
Basic, Standard and High profiles adjust how many challenges are required, so you can tune friction versus assurance per use case.
Local AI models
Face analysis and vision-language OCR models run on the server you control. No third-party biometric cloud is involved.
Full audit trail
Every verification session is logged with its results, timestamps and confidence scores, ready for compliance review.
Who it is for
Built for regulated and high-trust environments
Banks & financial institutions
Digital customer onboarding with KYC/AML-aligned identity checks.
Fintech & crypto
Fast remote verification for account opening and transaction security.
Healthcare & telemedicine
Face login for medical equipment and kiosks — patient identification without passwords.
Government & public services
Citizen identity verification for digital services, with data kept on national infrastructure.
eCommerce & marketplaces
Seller and buyer verification to reduce fraud and chargebacks.
Corporate security
Employee and visitor verification for physical and digital access.
Case study
Face login for telemedicine equipment — delivered as full source
A telemedicine equipment provider needed KYC-grade identity checks to control access to medical machines. They licensed the complete system as source code: liveness detection, document scanning and face login now run on their own hardware, with no per-use fees and no external cloud.
- Full source license, deployed on their infrastructure
- Sub-second face login for machine access
- No per-verification fees, no third-party biometric cloud
For developers
Integrate in an afternoon
The full verification flow is driven by a small set of REST endpoints. Start a session, stream camera frames, upload the document, request the match.
Core endpoints

Endpoints that return stored personal data require an X-API-Key header issued per integration. The demo-flow endpoints above are public so the live demo can run, and are rate-limited.

Web demo
Complete the full KYC flow — liveness, document scan, face match and fingerprint capture — in your browser, using your camera.
Launch the live demoAndroid app
Try touchless four-finger fingerprint capture and the mobile KYC flow on your own device. Direct APK download.
Download the Android appThe demo is a shared evaluation environment. Please avoid submitting real personal documents unless you are comfortable doing so — test documents work fine.
Note: the public demo runs on a shared, CPU-only evaluation server. Production deployments run on GPU hardware sized to your volume and respond significantly faster — ask us for a walkthrough at production speed.
Pricing & engagement models
How to buy
Three ways to get the system — start small, own it outright, or anything in between. Prices are starting points; the final quote depends on scope, volume and support level.

Questions
Frequently asked questions
How does the liveness check stop photo or video spoofing?
It combines several independent checks — natural blink detection and timing, head movement, face-size consistency, texture analysis and screen-reflection detection — so a printed photo, a replayed video or a face on a screen fails the check. You choose how strict it is with Basic, Standard or High profiles.
Which identity documents are supported?
Passports, national ID cards and driver's licences from any country, in any language. The OCR extracts the fields and standardises them into clean, structured data regardless of the document's layout or language.
Where is my data processed and stored?
Entirely on infrastructure you control. The face-analysis and OCR models run on your own server — no third-party biometric cloud is involved — which is what makes it straightforward to align with GDPR, CCPA and KYC/AML requirements.
Can I integrate it with my existing app?
Yes. Every step of the flow is a REST endpoint, so you can drive it from web, mobile or desktop. There is also a native Android app and a one-shot face-login endpoint for kiosks and returning users.
Can I try it before committing?
Yes — the live web demo and the Android app are both free to try right now, with no sign-up. Use test documents rather than real personal documents in the demo.
How accurate is the face matching?
The live face is compared to the document photo and scored against a confidence threshold you configure. You decide the cut-off that balances false accepts and false rejects for your risk profile.
Can we buy the source code?
Yes. The system is available as a full, non-exclusive source license — the complete codebase and build documentation, with a handover support period — so OEMs and integrators can own the technology outright. See 'How to buy' above, or contact us.
Do you charge per verification?
No. Deployments and source licenses are flat-priced: you pay for the deployment or the license, not for each check. That is the main cost difference versus per-verification cloud KYC providers once your volumes grow.
Is the live demo the same speed as production?
No — the demo is a shared, CPU-only evaluation environment. Production deployments run on GPU hardware sized to your volume and respond significantly faster. We are happy to show a production-speed walkthrough on a call.
