Lumidigm Venus Series Fingerprint Sensor

IP65 Rating - Waterproof, Great for using it outdoors

The fingerprints are captured by exposing the fingerprint surface and subsurface (from below the surface of the skin) at the same time. This enables the Venus Fingerprint Sensors to capture clear and clean images every time, even when surface features are absent or hard to distinguish due to age, dirt, finger pressure, and skin or environmental conditions.

The Venus Fingerprint Sensors enroll and verify every fingerprint including those that thwart conventional sensors.

Dirt-proof biometric reader

To get the most accurate fingerprint reading yet, this scanner shines polarized light on your finger, creating an image of your prints and blood vessels from the red, blue and green wavelengths that bounce back. It works through latex and paint—and even underwater.

Lumidigm Venus Series fingerprint sensor is used in the access control device is shown in the video below:

Lumidigm has developed a multispectral imager that is able to collect additional information from below the surface of the skin. Unlike traditional technology, multispectral imaging technology is not dependent on the quality or authenticity of the fingerprint ridges presented. The Lumidigm sensor can look beyond surface ridges to verify their authenticity and enhance the identifying image.

If a finger with worn ridges presses the platen, the Lumidigm sensor can read the unique unaffected fingerprint under the skin and enhance the image. Similarly, if there is water or “normal” city grime obscuring the surface ridges, or if the finger isn't fully touching the sensor, environmentally robust multispectral imaging technology can enhance the incomplete surface ridge information with data from below the surface of the skin.

Spoof Detection

The Lumidigm sensor’s spoof detection ability is unique Multispectral imaging technology can detect a fraudulent fingerprint (a “spoof”) easily by measuring the subsurface data (or lack of subsurface data) against known characteristics of living skin. It can even compare subsurface data to surface data to make sure that they are the same.

Thus, multispectral imaging technology is a revolutionary access control system that is vastly superior to conventional fingerprint technologies. Currently deployed systems cannot obtain adequate fingerprints from up to 16% of the population; Lumidigm sensors can reduce that rate to nearly zero.
