Biometric identity verification using NFC and selfie matching
Verify that the person holding the identity document is the legitimate owner. ID Scan reads the original portrait directly from the NFC chip, performs liveness detection on the device and compares the live selfie with the document portrait.
Original portrait directly from the NFC chip
ID Scan reads the original portrait photo stored in Data Group 2 (DG2) of the passport or identity card. The portrait originates directly from the issuing authority and can be used as the trusted reference image for biometric verification.
DG2 portrait extraction
Retrieve the original document portrait from the NFC chip.
Issuer-signed data
The portrait is protected by the document's digital signatures.
No document photo dependency
Use the original chip portrait instead of relying on a photo of the physical document.
Liveness detection on the user's device
Before a selfie can be accepted, ID Scan checks whether a real person is present in front of the camera. This liveness step is performed locally on the mobile device and does not require an external biometric verification provider.
Real person detection
Verify that a person is physically present during the scan.
Anti-spoofing
Help reduce fraud involving printed photos, screenshots and screen replays.
No external provider
Biometric processing can be performed on the device instead of in a third-party cloud.
How biometric verification works
The verification flow combines document authenticity, the trusted chip portrait and a live selfie check in one guided mobile process.
Scan MRZ
The MRZ is used to access the NFC chip.
Read DG2 portrait
The original portrait is extracted from the document chip.
Capture live selfie
The user takes a live selfie while liveness checks are performed locally.
Compare and verify
The selfie and DG2 portrait are compared and the result is returned through the API.
Biometric processing without external verification providers
ID Scan is designed for privacy-sensitive identity verification. The selfie check, liveness detection and face comparison can run locally on the mobile device. This helps organizations avoid sending biometric images to external cloud verification providers.
On-device processing
Perform biometric checks directly on the user's phone.
Privacy by design
Share only the verification result and the fields required for your process.
Reduced data exposure
Limit unnecessary transfer and storage of biometric data.
Verification results protected by EU electronic sealing
Verification results can be included in a digitally signed PDF report protected by an EU electronic seal and trusted timestamp. This creates a tamper-evident record of the performed checks.
Face comparison result
Include the selfie match result and verification status in the report.
EU eSeal
Protect reports against unauthorized changes.
Trusted timestamp
Demonstrate when the identity verification was completed.
Why NFC and selfie verification are stronger than a document photo
Traditional document uploads only show the document. They do not prove that the document owner is present. By combining NFC chip verification, DG2 portrait extraction, local liveness detection and biometric face comparison, organizations can verify both the document and the person presenting it.
Useful for onboarding and compliance workflows
Biometric identity verification can be added to existing software through an API-first workflow. It is useful where organizations need more confidence than a visual document upload can provide.
KYC and AML onboarding
Verify identity during regulated customer onboarding.
Accountancy and legal software
Add trusted identity verification to client and dossier workflows.
HR and worker onboarding
Verify employees, contractors and temporary workers remotely.
Add biometric identity verification to your software
Combine NFC verification, DG2 portrait extraction, on-device liveness detection and selfie matching in a single API workflow.
