Intelligent Contactless Palm Vein & Geometry Access Control Terminal An advanced, edge-computing biometric access terminal utilizing near-infrared (NIR) sensors to verify identity through internal palm vascular structures and unique hand surface geometry. Operating on an IP-based network framework with native OSDP and PoE+ support, this contactless device maps thousands of hidden vascular nodes to grant secure entry in under 0.3 seconds—delivering an un-spoofable, completely touchless biometric credential that works independently of surface dirt, cuts, or skin pigmentation.
Subcutaneous Vascular Mapping for Ultimate Anti-Spoofing Security
While fingerprint and facial recognition systems handle the bulk of standard commercial access control, certain high-traffic or highly sterilized environments demand an alternative approach. Fingerprint scanners face challenges in heavy industrial zones due to surface dirt, moisture, or micro-scratches on an worker's skin. Meanwhile, facial recognition can encounter lighting issues or privacy resistance from staff. A Palm Recognition Device sidesteps these hurdles by looking beneath the surface of the skin, capturing the complex network of oxygen-depleted veins running through an individual's palm.
The terminal operates via an intelligent, non-contact edge-computing sensor matrix. When an occupant holds their open hand 15 to 30 cm above the scanning deck, the device illuminates the hand using a safe, low-energy Near-Infrared (NIR) Light Array. Because deoxidized hemoglobin in the bloodstream naturally absorbs near-infrared light, the veins show up beneath the camera as a highly distinct black pattern.
The onboard neural processing unit (NPU) instantly maps this internal vascular map along with the hand's structural surface geometry, converting it into a secure, encrypted mathematical token. Because this pattern relies on active blood flow inside living tissue, it is physically impossible to spoof using high-resolution photographs, silicone molds, or detached replicas.
Key Performance Features
Absolute Resistance to External Factors: Because the sensor reads internal vascular structures, authentication accuracy is completely unaffected by skin abrasions, superficial cuts, dirt, lotion, hand wetness, or natural aging.
100% Touchless and Sterile Interface: Users authenticate completely in mid-air without touching a physical screen or sensor plate, preventing cross-contamination in medical environments.
Rapid, High-Throughput Verification: High-performance internal processing executes template matching in $\le 0.3\text{ seconds}$, keeping entry points moving smoothly during high-volume shift changes.
Advanced Multi-Factor Credentialing: Features built-in hybrid options, allowing entry configuration via palm vein only, palm + RFID smartcard (MIFARE DESFire/HID iCLASS), or palm + a digital PIN code via an integrated touchscreen panel.
PoE+ Simplified Infrastructure: Supports Power over Ethernet (IEEE 802.3at), combining system data networks and the 12V DC power lines required to actuate security door locks into a single Cat6 line run.
Local Offline Autonomy Enclosure: Houses an on-board non-volatile flash core capable of storing up to 5,000 unique palm templates and 100,000 transaction event logs completely offline, preserving perimeter defense during network dropouts.
Ideal Infrastructure Applications
Hospital Surgical Cleanrooms & Clinics: Granting sterile, touchless door overrides to medical professionals wearing surgical scrubs and personal protective equipment.
Heavy Industrial & Chemical Plants: Providing reliable biometric identification for industrial laborers whose fingerprints are frequently obscured by oil, grease, or heavy work gloves.
High-Privacy Data Centers & Cash Vaults: Securing high-value network infrastructures with an internal biometric signature that cannot be photographed, copied, or stolen remotely.
