Researcher in biometrics working on contactless palm/finger recognition here. 1) A new innovation ok. People have been doing that for more than a decade, my group included. 2) Given the sensors look, it's almost certainly near infrared (NIR) camera, probably 850nm illumination and the dark surface is a NIR filter. 3) It certainly capture a mix between palm veins (850nm quite absorbed by de-oxygenated hemoglobin) and palm skin ridges. "Rather, the images are encrypted and sent to a highly secure area we custom-built in the cloud where we create your palm signature." 4) Weird approach to biometric template security to send palm picture to a server... 5) Curious how anti-spoofing is implemented, if at all. edit: less agressive
