For all the popularity of fingerprint scanners, Fujitsu believes that it can go one better. The Japanese company has been working on palm-based systems for the last few years, and we've already seen turnstiles, wallets and tablets that are accessed from your hand. Fujitsu believes that palm vein sensing is around a thousand times more secure than conventional biometric methods and it's implementing the technology in its next range of business-focused laptops due out this week. We've been shown around some of these models, which have the new sensor fitted into an area that is roughly the same size and position as the company's existing fingerprint scanners, just below the bottom right corner of the keyboard. Using it is simple: Hold your hand a few inches above the sensor and the hardware will quickly scan the unique arrangement of your veins. If it judges you to be the real deal, it'll open up its secrets for your enjoyment.

Of course, your biggest objection to that would be that, if some nefarious type wanted to get at your Amazon account, all they'd have to do is grab a sword and lop off your hand, right? Turns out, biology has provided us all with a built-in failsafe. Fujitsu's technology only works while blood is flowing through your veins, so your lifeless limb can't be used to breach the wall. Having seen this technology in action, we're reasonably sure that it's ready for prime-time, and we're excited to see if this as fool-proof as Fujitsu claims. Even if it is, however, the easiest and least messy way to access someone else's login will always be to ask them -- an approach that worked just fine for Edward Snowden.
