In this video, the SMACS access control technology is used to conduct a 3D biometric scan at an entry point and grant or deny a person access, including in a potential hostage situation. It is a good example of how biometrics technologies are used today in commercial environments.
More info on SMACS: SMACS stands for Smart Airlock Control System. These systems are used commercially, for example, in some Swiss banks and in a variety of sensitive data centers, airports, and other physical locations where entry must be secure. SMACS systems can contain a variety of sophisticated 3D biometric scanners, for example, to determine how many people are in an entry area, with some systems also using 3D face recognition readers.
This video is part of the World Privacy Forum series of biometric videos. This footage was shot on location in London, at the Biometrics 2013 conference.
