If a finger print scanner isn’t quite enough for you to feel comfortable with keeping your data on a portable USB flash drive you will want to take a look at the Irikon Flash memory device from Rehoboth Technology.

This thumb drive has biometric security similar to many flash drives that use finger print scanners except that this one requires a scan of your eye, or your iris to be exact, to authenticate your access of the drive. It can remember up to 20 different irises and is USB 1.1 and 2.0 compatible. Not a whole lot of detail is given about how the iris scanning part works other than you need to look into the iris camera from no further away than 6 cm.

The Irikon has an on-board rechargeable battery that charges up when it’s connected. This to us implies that the iris camera must work when its not connected to the computer (which I guess might be difficult when connected, anyway). The drive is only 30 cm long and must be pretty accurate since it has a .1% false reject rate. It comes in sizes of 1GB, 2GB and 4GB, but no pricing or time table for availability (or a better photo) was given.
