Free 14-day trial · no credit card
Biometric verification that stays on the phone, by default.
Contactless fingerprint and anti-spoofing face SDKs for mobile apps. Capture and processing run on the device and the standard SDK sends nothing off it. Need audit trails? Optional packages add server-side session evidence.

Integrate and verify
Add the SDK, initialise it with your key and capture and process on the device, then compare templates locally or against your own API.
Products
Two SDKs, one integration model
Contactless Fingerprint SDK
Verify identity with a fingerprint captured by the phone camera. No scanner hardware, no touching a shared sensor, and processing stays on the device.

Face Anti-Spoofing SDK
Face recognition with liveness detection that rejects photos, screens, masks and replays, processed on the device.

Why ArcID
Built to be trusted, not just accurate
Contactless fingerprint
Capture a fingerprint with the phone camera. No scanner hardware and no touching a shared sensor.
Face anti-spoofing
Face recognition with liveness detection that rejects photos, screens, masks and replays.
On-device by default
Capture, liveness and template extraction run locally, so the standard SDK has no biometric cloud service to build, host or secure. Matching is yours to run: locally or against your own API.
Works offline
After one license check, verification keeps working without connectivity, with a generous grace period.
App-bound licensing
Each license is bound to your registered app ID and signed, so it can't be reused in another app.
Four platforms
Native Android, native iOS, React Native and Flutter with the same capabilities on each.
Compared
On-device vs. cloud verification
Most biometric vendors send images to a cloud API. Our standard packages keep capture and processing on the device, which changes what you have to build, secure and explain to auditors.
| ArcID (on-device) | Cloud biometric APIs | |
|---|---|---|
| Biometric images leave the phone | Not with standard packages | On every check |
| Backend you must build and secure | None for standard packages | Required |
| Works without a connection | Yes | No |
| Network calls by the SDK per check | None | Every request |
| Biometric data held by the SDK vendor | None (standard packages) | Images or templates in the vendor's cloud |
Optional session-evidence packages add server-side statistics, frames, proofs and records for audit purposes. Those packages do send per-session data to a backend, and are chosen per app.

Your users' biometrics stay under your control
Processed on the device
With standard packages the SDK never sends images or templates to us or to any server. Its only network call is license verification.
Signed, app-bound licenses
Licenses are cryptographically signed and tied to the app ID you register, so they can't be forged or moved.
You choose the data flow
Standard packages keep everything on the device. Optional packages add server-side session evidence (statistics, frames, proofs and records) when you need an audit trail.
