Step 1 · Capture
Read below the surface.
Palm-vein recognition looks beneath the skin. Near-infrared sensing reveals the vascular pattern inside the hand and turns a simple palm hover into a usable biometric identity.
How your palm becomes your most secure identity.
Palm vein authentication reads the vascular pattern beneath your skin using gentle near-infrared light. It is 100% contactless, deeply private, and impossible to clone.
HOW IT WORKS
From your palm to a connected identity.
Capture. Verify. Match. Connect.
Step 2 · Verify
Verify with a hover.
Hold your palm above the sensor. The system captures the pattern without physical contact, verifies the identity and can immediately use that verification for experiences such as checkout or access.
Step 3 · Match
Match where you need it.
The same palm identity can work across different terminal formats and environments. Verification can be handled on the device or through connected infrastructure depending on the deployment.
Step 4 · Connect
Connect one identity everywhere.
Once palm identity becomes part of the platform, it can connect with access systems, attendance, payments, terminals and software through the same underlying identity layer.
Biological Superpowers
Four reasons why palm vein beats every legacy credential
Hidden Inside Your Body.
Fingerprints leave grease on glass. Faces can be photographed from afar. Your vein network lives securely beneath your skin.
100% Unique to You.
Even identical twins sharing identical DNA and facial profiles have completely distinct vascular vein layouts.
Stable for Life.
Unlike fingerprints that fade with manual work or age, internal adult vein patterns remain structurally unchanged over time.
Works in Any Condition.
Wet hands, dusty palms, light surface cuts, or dry skin never disrupt reading. 99.99% reliable verification every time.
Direct Comparison
Why palm vein outperforms fingerprints, face recognition, and cards
| Palm vein | Fingerprint | Face | Card or PIN | |
|---|---|---|---|---|
| Physical contact with scanner | None (hover 5 cm) | Direct touch (hygiene risk) | None | Touch or tap |
| Where the credential lives | Under the skin (hidden) | On skin surface (leaves residue) | In public view (photographable) | Plastic card or in memory |
| Can be lent to a friend or cloned? | Impossible | High risk (silicone / latent print) | High risk (photos / deepfakes) | Trivial (borrowed or duplicated) |
| Failure due to sweat, dirt, or light | Zero impact (reads internally) | High (sweaty, worn, or dusty) | High (glare, shadows, face masks) | Damaged chip or dead phone |
| False acceptance rate (security) | 1 in 10,000,000 (military-grade) | 1 in 100,000 | 1 in 100,000 | Anyone holding the card passes |
End-to-End Architecture
From optical sensor to door unlock in 300 milliseconds
A certified terminal running the Veinz Edge SDK captures the optical vein reflection. The Auth Gateway compares the encrypted vector against the local secure enclave or cloud vault.
The Policy Controller evaluates permissions, and Veinz Core commits the event to your campus or corporate ledger — unlocking turnstiles, recording class attendance, or executing your cafeteria payment.

Frequently asked questions
Is near-infrared light safe for my hands and eyes?
Completely safe. It uses the exact same low-energy infrared frequency found in standard television remotes and smartphone proximity sensors, well within international eye and skin safety standards (IEC 62471).
Do you store a photograph of my palm?
Never. Veinz does not save photographs, images, or raw video. The camera frame is converted in volatile memory into an encrypted numerical hash, and the original frame is instantly destroyed.
What happens if I have a cut or scrape on my hand?
Surface cuts, dirt, or ink on the skin do not affect verification because the near-infrared sensor looks underneath the outer skin layer at deep subcutaneous veins. You can also enrol both hands so either one works.
Can someone fool the scanner with a printed picture or 3D mold?
No. Veinz incorporates active liveness detection. The sensor specifically measures the absorption of near-infrared light by moving, deoxygenated hemoglobin. Artificial models, photographs, and non-living tissue have zero signal.
Can I delete my biometric data at any time?
Yes, absolutely. Under India's Digital Personal Data Protection (DPDP) Act, you have the right to erasure. A single click from your user app or an email to privacy@veinz.co permanently purges your encrypted template across all devices and servers.
