Biometrics solutions

VIRDI terminals and readers is a high-class equipment for companies and institutions who appreciate the safety, comfort and functionality that comes with fingerprint solutions. Access control and Work Time tracking systems based on VIRDI terminals are implemented in various manufacturing companies, corporate offices, health care institutions, public administration offices, legal and educational institutions,  or at airports.

Fingerprint Recognition System

1. Acquisition of fingerprints
   The optical fingerprint recognition sensor consists of a light source, a prism, a lens, and an image acqui-sition device (CCD). The input light from the light source creates the image of the fingerprint on the prism, and delivers it to the CCD.
2. Derivation of Characteristics
   Character points and special points of fingerprints are derived through the process of improving the quality of the fingerprint image to read the ridges, finding the directions of each ridge, separating the ridges and the valleys, and making the ridges into 1-pixel thick lines.
3. Matching
   Matching is a process of measuring the degree of similarity between two fingerprints. Scores are calculated on the correspondence of characteristics, and the scores have to be higher than a certain level in order to determine that two fingerprints match.
   Character points of fingerprint images are derived, and compared with those stored in a database to calculate the matching scores.

Access Control with Fingerprint Technology

Today, fingerprint recognition technology is used for security purposes, to restrict assess or to protect computers. It’s mainly use to prevent unauthorised access attempts to cash machines, personal computers, computer networks, mobile phones, home alarm systems, door locks and chipcards. Furthermore, in public utility offices as well as in companies, fingerprint systems help track chosen people and support Work Time registration. Read more on Access Control

Work Time Tracking Based on Biometry

Virdi systems are an ideal composition of Access Control with Time&Attendance Control. They provide an optimal verification (identification) of people. VIRDI Systems do not eliminate readers for password (PIN) or RF cards, allowing to use any two verification methods together, eg. Fingerprint with RF cards, or fingerprint with PIN code. Work Time Tracking based on biometry is comfortable for users and most reliable for employers. Read more on Time&Attendance

Future of Fingerprint Recognition

As fingerprint recognition technology develops, it is expected that more affordable and more portable fingerprint recognition devices will become available, and finger-print recognition will be considered a safe and convenient personal identification system.

Eventually, fingerprint recognition will be used to secure the safety and reliability of a variety of businesses in the industrial sector, including the personal devices and financial industry.

Fingerprint Recognition Sensor

VIRDI fingerprint recognition sensor boasts high durability and stability. If produces high-quality fingerprint images that eliminate distortion and afterimage created by the optical sensor.
