A gun is one of the more obvious examples of the use for recently developed grip profiling technology. This works not so much because people always hold things in exactly the same way, so much as the shape of our hand determines the distribution of pressure, in a recognizable way. Smart gun, dumb dumb bullets.

This is an ATM in Japan, incorporating a full palm vein scanner. In other words, rather than fingerprint recognition, the shape of veins in your hand gives a distinctive and uniqe pattern.

Once parents hear the patter of tiny feet, they fear the clatter of tiny fingers - on Daddys computer, which is connected to the Internet where there are naked people. <p /><p />Biometric keystroke recognition claims to be accurate in identifying signature keystrokes, which would be fun to try with cats, who seem to love walking over keyboards.

Hitachi has recently developed a vein recognition system that sits neatly behind the steering wheel of a car so you can burn 0.0001 calories less to authenticate yourself.

People are only just beginning to talk about biometric touch pay systems in the US. In October 2007, Shanghai launched a working version of a fingerprint payment system.

If you want to try this at home MIT even provide downloadable source code for this projects which identifies people by the way they walk. Including John Travolta and John Cleese.

A spook’s Gameboy. Three thousand of these science fiction like devices are actually deployed into places like Iraq for use by defense agencies in ‘enrolling’ - a euphemism for something that is rarely voluntary.

The handheld device stores up to 10,000 full biometric portfolios (2 iris templates, 10 fingerprints, a facial image and biographic data).

This hand held device is used by soldiers at checkpoints to do iris scans of people and match against a stored database of up to 100,000 people.

&quot;The BioID Pupil Tracker is tracking an eye pupil in a video stream - in real time. In addition to the tracking of the eye pupil the system detects the state of closed eye.&quot;<p /><p />No more napping in your cubicle if Big Brother is watching.

Iribio, which stands for Iris Bio Technology developed a regular mouse with a full iris scanner built in to allow iris scanner access to an individual PC.

There are plenty of signature recognition products, however the bio pen has the recognition mechanism within the pen itself

The possibility of cheaper biometric recognition being built into standard PDAs is now becoming a reality. Here is a link to OKI’s plans for iris recognition in PDAs.

This combination device designed for immigration officials has simultaneous recognition of face, fingerprint and iris. And it looks like the memory erasing device from the movie ‘The Men in Black’.

IDesia create a product called the BDS (not the BS) which captures a unique electrical signature recorded by placing fingers on the pads.<p /><p />This sounds very much like a Dianetics machine, although the application here sounds plausible.

A Japanese Flora Se210 laptop with integrated vein recognition since 2005.

LG Iris recognition entry systems, such as this one, are the devices used for entry in places like the Los Alamos labs. Linked to here are some suitably impressive flash movies of LG Iris systems.

Humabio stands for Human Monitoring and Authentication using Biodynamic Indicators and Behavioural Analysis. In a nutshell they are trying to create biometric authentication based upon the way people think.

If you want to understand more of what they are up to, check out the entertaining scenarios in their website’s vision section.

Lumidigm Biometric Fingerprint Sensors go beyond normal finger print scanners to use skin spectroscopy to identify based upon color patterns beneath the skin.<p /><p />What this means, of course, is that whenever you see someone in a movie breaking into a secret facility with a fake fingerprint, the secret facility is being protected by a $5 keychain device, not one of these.
