The iris USB drive requires a user to look into the on-board camera for a quick looksie. The registration or scanning process will ID the user in around 2 seconds. There are no passwords or pin numbers to unlock the drive, only the correct iris will unlock the valuable content. With 256-bit encryption I don’t think you’ll get past this, even with some James Bond contact lenses.
The Irikon drive can hold 20 iris templates or IDs and is fully plug-n-play with Windows, Mac etc. You will need to get the iris ID drive fairly close, about 6 centimeters.
