Knowing YOU...

by the back of your hand

The Hand Vascular Pattern Recognition (HVPR) technology verifies users utilizing individually unique vascular patterns
extracted from the hypoderm below the surface of the skin of the back of the hand using an infra-red based sensor device.
  • Usability/Accuracy/Speed
    By utilizing individually unique Hand Vascular Patterns, 99.98% of the entire population is able to use the system accurately and with the verification speed of 0.4 seconds, eliminating user bottlenecks and the requirement of a workaround backdoor security access process that is a potential security risk.
  • Eliminate Spoofing
    The HVPR system uses the vascular data on the blood vessels dispersed in the hypoderm below the surface of the skin on the back of the hand using infrared light, making it 100% tamper-proof.
  • User privacy protected
    User privacy is assured as the hand vascular data is only enrolled and verified with the user voluntarily providing their hand to a HVPR scanner. The vascular pattern cannot be viewed by the naked or be inadvertently left behind by user; therefore, there are no police databases of vascular patterns. This eliminates privacy concerns users have with other biometric modalities.
  • Harsh Environment Robustness
    Since the unique vascular pattern from below the surface of the skin is utilized, scars or contamination of hands rarely affects it. This results in no performance degradation in harsh environments.
An example of vascular pattern extraction

  • Placing hand
  • Raw image
  • Extracted pattern
  • Encryption
  • Database
Verification Process

  • Enter your PIN or present a card
  • Place your middle finger between the two guide bars
  • Insert your hand all the way in until contact is made with the webbing in between your fingers, and press the trigger switch gently by raising your wrist smoothly up to the switch

VP-II X
VP-II X is a biometric scanner that verifies users using the HVPR (Hand Vascular Pattern Recognition) technology, and is used for security access control or time and attendance. The VP-II X Scanner provides various interfaces with external devices through its digital I/Os, RS232, Wiegand inputs/outputs and TCP/IP ports. VP-II X has a built-in antenna to read a card, and a card reader module can be optionally installed inside the scanner. Supported card modules are proximity, iClass, Mifare and Ferica

VP-II XG (Door Controller)
The VP-II XG is a Door Controller for the VP-II X Scanner to connect and control an electrical door-lock. The VP-II XG is separately provided and is connected to the VP-II X via RS232 (or RS485; an optional RS485 driver board needs to be installed at both VP-II X and XG to use RS485 interface), typically installed on the secure side of the door. The VP-II XG has a relay output to connect an electrical lock and digital input ports for door status monitoring and exit button interface.

Input for exit button
Input for door sensor
Input for fire alarm
Power consumption 18W (DC 12V, 2.5A)
Dimension 194(W) x 197(H) x 45,7(T) mm

VP-II XC (Access Control Unit)
The VP-II XC is a two channel Physical Access Control System (PACS) for Wiegand input devices such as proximity or smart card readers. The VP-II XC is recommended for use when non-biometric card readers are used for some doors while the VP-II X Vascular Scanners are used for some doors at one site. The VP-II XC is connected to the server application software (VP-II NetControl-X) through TCP/IP Ethernet and operates in the same way as the VP-II X Scanner for access control functions, the only difference is that the VP-II XC validates only the card ID or PIN from the Wiegand input port, instead of the user’s hand vascular pattern. It also provides connection ports for an electric lock (Dry contact relay outputs), exit button, sensors for door and lock monitoring, and fire alarm input. Each channel functions fully independently.
