Even those who use public computers will occasionally forget to log off, but with the SonarLocID Keyboard hooked up to shared PC terminals, you won't have to worry about classified information getting into the wrong hands.

Engineered by Key Source International, the SonarLocID Keyboard uses inaudible sound waves to sense the presence of fingertips typing. Once the user has removed himself from the workstation with enough distance, the techie security accessory will prompt the login screen to protect your session.
