Hand Vascular Scanner
The Hand Vascular Pattern Recognition (HVPR) technology scans the back of your hand to recognize your unique vascular patterns to provide access. It's fast, accurate, and completely touchless.
What is HVPR?
The Hand Vascular Pattern Recognition (HVPR) technology identifies users by scanning the back of their hands using an infra-red-based sensor device. Our VP-II X Scanner uses a patented HVPE (Hand Vascular Pattern Emphasizing) algorithm to increase the pattern recognition performance by enhancing the weak vascular vessel images.
Benefits of HVPR
Accuracy & Speed
By utilizing individually unique Hand Vascular Patterns, 99.98% of the entire population can 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.
Safe Against 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.
Privacy Protection
User privacy is assured as the hand vascular data is only enrolled and verified with the user voluntarily providing their hand to an HVPR scanner. The vascular pattern cannot be viewed by the naked eye or be inadvertently left behind by the user; therefore, there are no police databases of vascular patterns. This eliminates privacy concerns users have with other biometric modalities.
Harsh Environment Safe
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.
HVPR Products
VP-II X
VP-II X is a biometric scanner that recognizes 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 FeliCa.

VP-II XG
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.
| Interface with VP-II X | RS232, RS485 (Option) |
|---|---|
| Door control | Dry contact output for door lock interface |
| Input for exit button | |
| Input for door sensor | |
| Input for fire alarm | |
| Power consumption | 18W (DC 12V, 2.5A) |
| Dimension | 190(W) x 197(H) x 45.7(T) mm |
VP-II XC
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.

Biometric Time and Attendance Terminal
Most Reliable Biometric Technology (HVRP)
VP-II X Time Clocks provide the most reliable biometric performance for identifying an employee to punch in/out for time and attendance by using state-of-art Hand Vascular Pattern Recognition (HVPR) technology utilizing the vascular patterns on the back of the hand.
Database Interface to many other existing systems
All or selected punches by user group and/or punch types are exported to 3rd party software’s database. Exported punch data may be used for time and attendance reporting and management.
Security Access Control Capability
VP-II X is designed to be used for both time and attendance and access control at the same time. A VP-II X being used for time and attendance can be easily used for access control purposes by connecting a VP-II XG Door Controller provided by Techsphere or by connecting it to an existing physical access control system.
Employee Time Management System
The included NetControl software with the VP-II X provides companies with the ability to track their employees' time without conflicts with the existing software, eliminating the need for additional vendor systems being purchased.
Display Recent Punches
A user can retrieve and view his/her recent punches on the VP-II X screen for up to 100 transactions.
Easy Integration into Existing Infrastructure
VP-II X is easily connected to existing network infrastructure via TCP/IP and/or Wiegand interface. In a TCP/IP network, employees once enrolled on any VP-II Time Clock, are automatically synchronized to all VP-II X Time Clocks on the network. VP-II X has a standard capability for up to 50,000 users, which can be extended.
