INTRODUCTION
Palm vein technology is one of the upcoming technology.
It is the world’s first contactless personal identification system that uses the vein patterns in human palms to confirm a person’s identity.
It is highly secure and accurate.
The contact less feature gives it a hygienic advantage over other biometric authentication technologies.
It uses the vascular patterns of an individual’s palm as personal identification data.
WHY VEINS ARE CHOSEN
When near-infrared light passes, deoxygenated hemoglobin in the blood flowing through the veins absorbs near-infrared rays, causing it to be visible as black regions to the scanner.
Arteries and capillaries, whose blood contains oxygenated hemoglobin, which does not absorb near-infrared light, are invisible to the se
