For a comprehensive look at the methodology behind FastAccess in general, we strongly recommend that you first read the Overview pages. 
Users simply present their face to the computer for fast, convenient, and secure access. No longer do they need to remember to log out when they leave or struggle to remember different passwords for different applications. Switching between users in a busy environment is fast and convenient. Previously open sessions of applications can be maintained securely between users.
IT has no proprietary hardware to install or maintain. There are no batteries to replace or badges to get lost or left at home. Security policy can be enforced and changed quickly and centrally. Audit logs gain a whole new dimension.
Sensible Vision’s years of experience helps provide the best performance and user experience. FastAccess not only looks good on paper, but has been used extensively in and optimized for the real world.
