Corporate overview

With sales of over 200 000 biometric products each year and a majority share of the Korean domestic market, Virdi Biometric Technology is a premium brand offering a comprehensive product range with superior technology and very competitive pricing.

Some of the key features common to all the Virdi Biometric Products are:

Live & Fake Finger detection

A patented three tiered approach incorporating IR scanning technology with the ability to identify the material the fingerprint is made of (chemical composition) such as Silicon, Rubber, Paper, Plastic, Gel, etc. A Capacitive Sensor built into the Optical Scanner to measure electrical discharge and intelligent algorithm to measure and compare image distortion.

Automatic Finger Scan

The Optical Scanner has a built in Capacitance Sensor to identify when a human finger is placed on the scanner and automatically start scanning the fingerprint. This has two advantages; it ensures that only human fingers are scanned and it assists with power saving, as the Optical Scanner does not need to be illuminated all the time.

Patented Search Algorithm

Incredibly fast and accurate template matching algorithm will complete a 1:1 match in less than .5 of a second, and a 1:N match for 1000 users in less than 1 second.

Registration & Authentication levels set by User

Each User can be enrolled and thereafter verified using custom registration and verification levels which have been individually configured to improve the scan rate of poorly defined fingerprints

Number of Enrolled fingers set by User

Each User can load between 1 and 5 fingerprints on the biometric terminal. The database can accommodate the enrolment of up to 10 fingers and can be set to check that similar fingers do not exist in the database.

Transaction Options Set by User

Each User can have their transaction methods individually assigned. I.e. Finger only, Pin + Finger, Card or Finger, Card & Finger etc. There are 10 combinations.

Templates Stored in device memory and/or on the server

When each User or Visitor is loaded on the biometric template management software, the operator can assign the User to be authenticated at all or only specific Virdi devices and can either download the User to the device for local authentication or store the template only in the application database for Server authentication, this helps to ensure that terminals do not get “clogged up” with out of date templates.

Push Technology

In order to minimize network traffic and provide a “real-time” update of transactions, the devices will “Push” their transactions to the Server as they occur. While templates are being sent to the Virdi devices, Users can continue to transact.

Optical Sensor (Patented)

The Optical Sensor has a patent on the angle of the prism which gives the optimal level of distortion for image capture. This means that the biometric image scanned on a Virdi Optical Scanner has a higher image quality than competitive products; furthermore the surface of the sensor is hardened and coated which makes it resistant to wear and tear including use in harsh environments. This has been field proven in a multitude of installations in Africa where some of the harshest environments exist and where abuse of technology is rife.

Interfaces

The Virdi Biometric Terminals are intelligent and available with a multitude of communication and interface ports. As standard they have TCP/IP for Template and Data management, Wiegand 26 & 34bit IN & OUT ports to connect 3rd Party RFID Readers or Connect to Access Control Controllers, On Board Relays with NO/NC and Motorised Lock Control, Door Status Monitor, Alarm Panel I/F and RS323/485 Ports.

Applications

The Virdi Biometric Terminals can either operate as stand-alone or networked / Server managed devices and incorporate the functionality required for Time & Access Management, Canteen Control, alternatively they can simply emulate a card reader for interfaces to legacy systems.
