Fujitsu has developed a contactless palm vein pattern authentication technology called PalmSecure. It uses the unique vein pattern in a person's palm, which contains over 5 million reference points and remains the same throughout one's life, to identify individuals with a high level of precision. The PalmSecure sensor uses near-infrared light to extract the vein pattern without touching the palm. This technology offers stronger security than passwords or ID cards as vein patterns cannot be forged or shared, while being hygienic, accurate, and easy to use.
