Access Control
The following is an example of how A4Vision technology can add security to airport environments.

An airport maintenance worker requires access to the runway and baggage handling areas. They would be equipped with an ID card which is part of an access control system. They would also have their facial 3D biometric stored which is linked to their Card ID number.

As the employee makes their way through the airport to the runway they would approach the secured door where a card reader and an A4 Vision face reader are mounted on the wall. The employee would swipe their card and immediately glance at the Face Reader for access. If their face matches the 3D face template linked to their ID card then they would be let through the door. If there is not a match then access would be denied.

Since the employees’ facial biometric template is linked to their ID card this solves the security issues dealing with stolen or skimmed cards. The card will only be valid when presented with the right face that matches the stored template linked to the card ID. In addition, lost cards become less of a risk for the same reason; the card will be useless unless used by the rightful owner.

Background Identity Verification
There is the possibility to keep previous employees’ biometric templates on file so if they try and reapply under a different identity they would still be linked to their biometric in the system. This makes the act of switching identities very difficult because their facial features will be on file and will be linked to their true identity.

Time and Attendance
Having a workforce enrolled in a biometric system has several other advantages in addition to security. With a 3D face biometric based time and attendance application there is full accountability with regards to which employees checked in at certain times and areas. A problem for payroll management and employee accountability with large workforces that require time cards is “buddy punching” which leads to inflated payroll hours, decreased productivity and possible security issues. Requiring a biometric to be verified as an employee clocks in solves this problem because the time and attendance system will be looking for a 3D facial verification with the card or pin number that is used to clock in / out. This makes it possible to verify where and when employees enter and exit certain facilities.
