DEVELOPER PLATFORM
Integrate palm biometrics in under 10 lines of code.
Modern REST APIs, type-safe SDKs, and local offline engines for palm enrolment, sub-second verification, and access policy. Test immediately with our mock sandbox — no physical scanner required.
Use Cases
Build frictionless biometric experiences
- Passwordless Web & App Login Biometric single sign-on (SSO) for internal portals and consumer apps.
- High-Throughput Attendance Turnstiles and wall-mounted tablets checking in 100+ students or workers per minute.
- Physical Door & Elevator Access Unlock server racks, executive suites, and research labs via standard Wiegand/OSDP.
- Instant Palm Checkout Line-busting payment kiosks and counter POS integrations linked to UPI rails.
Engineered for Every Platform
Native SDKs tailored to your development stack.
Terminal Edge SDK.
C++, Rust, and Android runtime for embedded turnstiles and kiosks. Supports offline matching in under 50 ms.
Auth & Identity SDK.
Node.js, Python, Go, and React libraries for user registration, MFA step-up auth, and session token issuance.
Enterprise Webhook Engine.
Real-time Kafka, Webhook, and REST endpoints to sync verified punch logs directly into HRMS, ERP, and SIEM.

}Developer Experience
Built by engineers, for engineers
Minimal API Surface.
Only 3 core endpoints (/enrol, /verify, /revoke) needed to power 95% of biometric workflows.
Zero-Trust Encryption.
Vascular data is encrypted with AES-256-GCM right on the optical sensor before hitting your network.
Hardware Simulator.
Develop and test your full UI flow without waiting for hardware delivery using our terminal mock CLI.
