What are biometric access control devices?
The definition of a biometric access control device is a single piece of equipment that employs biometric readers or sensors to enable secure access to restricted areas without entering a password. The type of biometrics used includes facial recognition, fingerprints, heartbeats, and iris recognition. Currently, the most popular option is facial recognition due to its simplicity and cost-effectiveness.
Facial recognition can be implemented with standard, commercially available video cameras connected to an analytical software solution. As individuals enter the camera’s field of view, their faces are compared to those in a database. Facial recognition is an apt solution for low-throughput environments but is difficult to scale efficiently.
The problem is that the underlying technology is often not capable of keeping up with identifying large numbers of people in a short time. This causes problems as individuals are incorrectly identified and access is erroneously permitted or denied. It is certainly not a frictionless experience.
More complex and accurate biometric access control devices make use of 3D facial modeling. This option is more expensive and can still be plagued by faulty recognition and reliability issues. Facial recognition and modeling are two technologies that will drive biometric access into the future. Research is continuing to refine the processes which are excellent choices for authentication in areas that require high security.
The following chart highlights research that indicates that biometric and RFID access control devices are a growing market that will dominate the area of physical access control. It’s expected to grow at a compound annual growth rate (CAGR) of 10.5%. The market is expected to grow to five billion US dollars from 2021 to 2031.
