Finger and palm vein reading refers to devices that use infrared light to scan and algorithms to encode the unique vein pattern on each person's palm or fingers. You can already access your laptop, your bank account, your car, and even your local library with vein identification systems, so it seems natural that your desktop should also get the same level of hardened security- and now it has. Eschewing a numberpad for the vein scanner, this particular keyboard is of the finger scanning variety.
