The LOK-IT is an encrypted flash drive that offers hardware authentication that renders it impervious to key loggers or other spyware. The secret passkey must first be keyed into the built-in number pad before plugging the LOK-IT into a USB slot, where it appears as a normal storage volume. Unplugging it automatically locks it, which is as fool-proof as you can get. Moreover, the LOK-IT is platform-independent and will work on any operating system and even office appliances such as scanners, projectors, and other mobile devices with USB OTG.
