How It Works

Blood in the veins contains deoxygenated hemoglobin. When exposed to near infrared (NIR) light the veins’ de-oxy hemoglobin absorbs NIR while surrounding tissue reflects it. This contrast in light yields the vein image.

Snowflake illuminates the hand with NIR then captures and processes the vein image. This image is processed to create a numeric “key” and the vein image is discarded.

After generation, the numeric key is enrolled for registration purposes or matched during the authentication process. Either way, Snowflake’s technology is simple to use and extraordinarily secure.
