This the only USB storage drive that secures its contents with a password spoken by its owner. With an 8 GB capacity for storing sensitive files such as contacts, financial data, or password lists, the drive's sophisticated voice recognition software detects the specific frequencies and nuances of its owner's voice. Requiring no software installation, operation is as simple as plugging it into a USB port and speaking a password--once authenticated, you can access stored files from your computer. Alternate secure entry is provided in the event of a cold, laryngitis, or a forgotten voice password. Works on any PC or Mac. 2 1/2" L x 3/4" W x 1/4" D. (1 1/2 oz.)
