This new technology is more than just a bio-metric print reader. The device actually scans a user's entire palm. One may wonder how an entire bio-metric reader for the palm can be done on the dimensions of a laptop. The answer is with conventional bio-metric technology. What Fujitsu has done is instead of using a bio-metric print scanner similar to the finger-print scanners on several modern day laptops, they have instead used a device that scans the veins in ones palm with near-infrared rays.
Laptops with Palm scanners should be even more secure than ones using finger print readers since it is harder to copy the vein signature of a palm than the images of one finger print from a convention bio-metric reader.
The way to use the device is to simply raise your hand over the reader, where it will then copy your vein signature in black and from there it will verify the hand to be the user's or someone attempting to break into the user's computer.
