Increasingly, security technologies have been developed to augment or replace the reliance upon the human element in the security infrastructure, and in addition to the use of biometric-based systems, various other technologies are widely used as part of physical security environment. In addition, some of these technologies have other applications, including use in asset tracking and logical access applications:
