On-device identity verification • NFC passport scanning • Privacy-first

On-device identity verification.

ID Scan performs identity verification directly on the user's mobile device. NFC passport reading, document validation and optional selfie verification can be completed without sending biometric data to external AI services.

Why on-device identity verification?

Many identity verification solutions rely on cloud-based processing for biometric comparison. ID Scan is designed differently: where possible, sensitive verification steps are handled locally on the user's mobile device.

Reduce data sharing

Biometric comparison can be completed without sending the live selfie to external AI services.

Support privacy by design

Local processing helps reduce unnecessary transfer and processing of sensitive personal data.

Clear explanation to users

Organizations can explain that the biometric comparison is performed directly on the user's device.

API-ready result

Your backend receives the verification result and only the configured fields required for your workflow.

How the flow works

The mobile app guides the user through a clear verification flow. The organization decides which fields and checks are requested, while the app performs the technical document and selfie verification steps.

1

Scan the document

The user scans the MRZ area of the passport or identity document to start the secure NFC reading process.

2

Read the NFC chip

The app reads identity data and the portrait photo from the chip, including DG1 and DG2 where available.

3

Optional selfie check

If requested, the user takes a live selfie that is compared with the portrait photo from the document chip.

4

Return the result

The API returns verification status, requested fields and check results according to the configured template.

Privacy-first architecture

ID Scan is built around a simple principle: process sensitive data only where it is needed. The mobile device performs the document scan and optional biometric comparison. Your system receives the result through the API.

Passport / ID document ↓ Mobile device ↓ MRZ scan + NFC chip reading ↓ DG1 identity data + DG2 portrait photo ↓ Optional live selfie ↓ On-device comparison ↓ Verification result via API

What can be verified on the device?

Depending on the document and the configured template, ID Scan can perform technical document checks and optional biometric comparison as part of the same mobile flow.

NFC chip reading

Read identity data, document details and the portrait photo from the secure chip in supported passports and identity documents.

Document checks

Check whether the chip was read successfully, whether document data is available and whether the document is not expired.

Selfie comparison

Compare the live selfie with the DG2 portrait photo from the chip directly on the user's device.

No external biometric AI provider required

For organizations that want to reduce third-party processing, on-device verification offers a clear alternative. The selfie comparison can be performed locally instead of sending biometric images to an external cloud service.

Local comparison

The biometric comparison is performed on the user's mobile device.

Less external processing

Avoid unnecessary transfer of biometric data to external AI or cloud verification providers.

Controlled API output

The API can return only the fields, images and checks that are explicitly requested.

Use cases

On-device identity verification is useful for organizations that need reliable identity checks while keeping the verification process privacy-conscious and easy to integrate.

Accountancy

Support KYC and Wwft onboarding flows with NFC-based identity verification.

Legal

Verify clients remotely while limiting unnecessary copies of identity documents.

HR and staffing

Verify employees, contractors and international workers during onboarding.

Software platforms

Add identity verification to your own platform using the ID Scan API.
