Your Palm is Your Key
Revolutionary biometric identity verification using palm vein pattern recognition. Secure, contactless, and impossible to forge.
The Palm Vein Advantage
Understanding the science behind the most secure biometric authentication available
Security
Vein patterns are located beneath the skin, making them impossible to capture without consent. Unlike fingerprints or faces, they can't be photographed or lifted. Palm vein biometrics are also impossible to forge — no photo, mold, or replica can replicate the infrared absorption characteristics.
Reliability
Every vein pattern is unique. Even identical twins have different vein patterns. The pattern remains stable throughout life, unaffected by aging, work, or environmental conditions. Works in all conditions—cold, heat, rain, sun.
Comfort
Your hand is all you need — no badges, keys, cards or other accessories to lose, forget, or have stolen. Your hand is always with you. Non-invasive and comfortable. Users simply wave their hand—no contact, no staring at cameras, no finger placement struggles.
Fast & Accurate
Authentication in under one second with accuracy rate above 99.99%—better accuracy than most other biometric methods.
Hygienic
Scan your palm without touching anything. Contactless scanning delivers the highest standard of hygiene — ideal for healthcare, food environments, and public spaces.
Human Verification
Infrared scanning requires a living hand with active blood flow to produce a valid scan. Without it, the scan fails — making it impossible to replicate by robots, AI, or any artificial replica.
Why Palm Vein is Superior
The table below compares common biometric identification technologies in terms of security, reliability, comfort, hygiene and privacy.
| Criterion | Palm vein pattern (Palmki technology) Best choice | Fingerprint | Facial recognition | Iris scan |
|---|---|---|---|---|
| Security | ||||
| Subcutaneous biometric trait The vein pattern is located beneath the skin and cannot be seen or photographed without a specialised infrared sensor. | ✓ | ✕ | ✕ | ✕ |
| High resistance to spoofing Subcutaneous vein patterns require an active infrared scan of living tissue, making spoofing extremely difficult. Iris recognition also offers strong resistance, but relies on an externally visible biometric trait. | ✓ | ✕ | ✕ | ~ |
| Reliability | ||||
| Very high recognition accuracy Palm‑vein and iris biometrics can achieve very high accuracy. Fingerprint and facial recognition performance depends more on skin condition, lighting and positioning. | ✓ | ~ | ~ | ✓ |
| Highly stable over time The vein pattern does not change naturally. Re-registration may be needed after a deep injury, but this applies to all biometric methods in such cases. | ✓ | ~ | ✕ | ✓ |
| Robust in industrial environments Reliable identification despite dirt, moisture, protective equipment or damaged skin. When wearing gloves, any hand‑based biometric requires removing them. | ✓ | ✕ | ~ | ~ |
| Hygiene & comfort | ||||
| Contactless and hygienic | ✓ | ✕ | ✓ | ✓ |
| Fast & comfortable Systems requiring very precise positioning, such as iris scans, may slow down throughput at access points. | ✓ | ✓ | ✓ | ✕ |
| Privacy & ethics | ||||
| Cannot be passively captured at a distance Palm vein patterns are located beneath the skin and require a dedicated infrared scan. Facial and iris biometrics rely on externally visible traits that can be photographed — iris is typically more difficult than face. Fingerprints may be collected from surfaces such as a glass. | ✓ | ✕ | ✕ | ~ |
| Not suitable for external surveillance Only facial recognition allows for passive, large-scale identification of people in public spaces. | ✓ | ✓ | ✕ | ✓ |
| Lower ethical & legal risk profile UGentThe lower the score, the safer and more privacy-friendly the method. Scale of 0 to 7 risk factors. | 2 / 7 | 4 / 7 | 7 / 7 | 3 / 7 |

Palmki System Architecture
A complete, modular solution built on three core components for maximum flexibility and security
The Sensor
Captures palm vein patterns using infrared imaging technology
The Controller
Processes biometric data and manages authentication decisions. Powered via PoE, with direct 12V/24V doorlock control, relay output, and versatile input.
Control Software
Manages users, access rights, and system configuration
The Palmki Controller: Your Central Intelligence
PoE Powered
Single Ethernet cable provides both network connectivity and power—simplifying installation (Direct 12/24V power also possible)
Direct Lock Control
Built-in 12V or 24V output to control electronic doorlocks directly with integrated relay—no additional hardware needed

Built for Privacy from Day One
In today's regulatory environment, biometric data handling isn't optional—it's critical. Palmki is designed with GDPR/AVG compliance at its core, giving you peace of mind and protecting your users' privacy.
Secure Local Processing
Biometric templates are created and stored only in the secure processor. Raw palm vein images are never saved or transmitted. Additionally, an encrypted token is generated based on the palm vein pattern, which can be used for secure, privacy-preserving authentication.
Right to Delete
Complete biometric data deletion on request, fully compliant with GDPR/AVG Article 17. No residual data, no exceptions.
Transparent Consent
Clear enrollment processes with explicit user consent. Users always know what data is collected and how it's used.
Data Minimization
Only essential biometric features are extracted and stored. We collect the minimum data necessary for authentication.

When deploying a biometric solution, always choose the most secure option available — particularly when handling sensitive personal data. Palmki uses palm vein biometrics, an internal biometric (beneath the body's surface), unlike fingerprints or facial recognition which are external and can be captured without consent. This distinction is critical for both security and privacy compliance. A 2025 study by Ghent University, commissioned by the Belgian Ministry of the Interior in the context of football safety and biometrics, independently confirmed palm vein biometrics as the most secure biometric solution available.
