The Evolution of Biometrics and Touchless Entry Strategy with Convergint & CrucialTrak

As companies continue to move forward in a post-COVID environment, many are considering migrating the enterprise to touchless access control. In an effort to continue educating companies on the basics of what they will need to achieve their desired outcome, Doug Greenwald from Convergint’s Advanced Solutions team met with Brett Mason, Director of Channel Sales, from CrucialTrak to discuss the evolution of biometrics and the process of implementing a touchless entry system in an enterprise.


The first topic discussed was how the evolution of biometrics has influenced the technologies available today.

According to Mason, one of the biggest drivers in biometrics’ evolution has been the need for increased security and accuracy, along with convenience. Until recently, the industry has been largely relying on touch-based fingerprint devices. However, due to natural oils, lotions and hand sanitizers, the fingerprint lens can get easily get smudgy or scratched, resulting in lowered effectiveness. Furthermore, fingerprint is relatively easy to duplicate, resulting in questionable security.

These shortages have led to the development of other, more expensive biometric modalities such as face or iris recognition. Yet, there have been challenges with accuracy and spoofing attempts related to facial recognition. When it comes to iris recognition-the biometric modality that has long been the most accurate biometric modality available, and still is compared to fingerprint and facial recognition-there are challenges related to the convenience of usage. The user should have a relatively short distance between their eyes and the sensor installed at a certain height.

Finally, the quest for a solution that is a reasonable investment, accurate, and easy to use led to the development of palm vein recognition, which is almost impossible to spoof while having a low FAR and FRR. In the industry, FAR and FRR are two terms to describe accuracy: FAR stands for False Acceptance Rate, FRR for False Rejection Rate. The lower the FAR & FRR, the more accurate the recognition is. On top of that, it is extremely fast and convenient to use: all you need to do is hold your palm up in front of the scanner.

When it comes to the technologies used in today’s touchless solutions, one of the biggest advancements taken in recent product development is better cameras. CrucialTrak’s facial recognition modality uses 80 nodal points to determine, for example, the distance between a person’s eye and nose or the depth of the cheekbone. Infrared cameras are deployed to help distinguish a photo from a live subject. Speed, efficiency as well as security have also been improved. CrucialTrak’s user database, with users’ biometric data, is highly secured and encrypted. Also, most of the readers have tamper protection, meaning that if anybody would try to steal a reader by ripping it off the wall, the data inside it would immediately be destroyed.

The last topic discussed was implementing a touchless access control system in companies, and what to expect when making the transition. According to Mason, a big advantage of the BACS™ system is that it operates on industry-standard technology. For example, units support Wiegand connection to interface with legacy access control. With the database being SQL based, the transfer of records and formatting is very simple. CrucialTrak also has some certified integrations with legacy access control manufacturers.

Enrolling biometrics is fast and can be done either at one of the readers or at an Enrollstation; an ergonomically designed device exclusively for biometric enrollment. It scans biometrics very quickly and accurately. At fastest, enrollment can be done in under a minute. Once the biometrics are enrolled and readers deployed in the premises, the employee can be authenticated in under a second.
