The hand for greeting - and for recognition.
Who does not know this: The Indian - at least in the film - raises his hand in greeting and says "Howgh". It's as simple as that with palm vein recognition. Just like the Indian, you hold your hand in front of the sensor and are reliably detected (or rejected).
The principle of palm vein recognition is based on the fact that infrared light is absorbed more strongly by venous blood than the surrounding tissue. In this way, the sensor's camera detects the complex vein pattern within the palm of the hand, which uniquely identifies a person. Compared to the fingerprint method, ten times as many points are scanned for identification, a total of around 5 million points.
Palm vein recognition is as reliable as iris recognition and as convenient to use as a fingerprint sensor. The contactless recognition also ensures excellent user acceptance, installation is much easier than iris recognition, and the veins under the skin cannot be read as easily as a fingerprint. These unmistakable advantages have contributed significantly to the increasing use of palm vein recognition.
