The way things are going, the palm (lowercase) may be the key to our schoolchildren's future. Imagine, if you will, a system where kids ID themselves for such everyday tasks as buying lunch at the cafeteria. Then later, they could use this "contactless biometric palm vein authentication system" for access to classroom desktops and laptops.
Actually, Fujitsu's PalmSecure technology will probably be used first by adults, given the almost-daily news reports of huge security breaches because of lost or stolen laptops. And, as Plastic Bamboo points out, the system's touchless feature makes it germaphobe-friendly--no small issue for either adults or children.
