Biometric Authentication Systems for Identification, Authentication and Verification


Unlike token-based access control, biometrics are unique to individuals, making them a reliable form of verification. Not surprisingly, biometric authentication systems are used by organisations around the globe to improve security. They combine biometric authentication systems with physical security entrances to absolutely prevent unauthorised users from gaining access. Either as two-factor or multi-factor authorisation access control systems, biometric devices provide an advanced method for uniquely identifying you based upon your unique biometrics.

What is Biometric Authentication?

Biometric authentication is a method used to identify you based upon your unique biological characteristics, such as fingerprints. Using biometrics in access control systems is rapidly becoming more popular. Biometric access control systems are used to compare your biometrics to an earlier stored data version. If both versions of characteristics match, the biometric authentication system can confirm authentication, verifying you are you. This form of access control is mostly used to manage access to physical and digital assets and to secure buildings, rooms and computing devices.

Types of Biometric Authentication Systems

Conventional access methods have their weaknesses – cards can be stolen, pins or keys can be forgotten. Biometric authentication systems use your biological traits, and so biometric devices can come in any of these forms:

  • Eyes – iris scanners
  • Eyes – retina scanners
  • Fingerprint readers
  • Hand geometry readers
  • Facial recognition scanners
  • Vein recognition scanners

How do Biometric Authentication Systems work?

The system behind the biometric authentication device stores data from all authorised users. In this case, a signature containing your identity, job role and unique biometrics. Once you have registered, the physical security entrance will read your biometric signature, compare it to the stored version and grant you access. Based upon your job role, the system can grant or deny access to certain areas of a building.

A Biometric Authentication System Alone is Not Enough

The same as with traditional access control systems, a biometric authentication system alone is not enough. Installed at a swing door, the system does not prevent multiple users going through on one credential. The biometric authentication system should be installed in a physical security entrance to prevent unauthorised entry effectively. When integrated in our most sophisticated entry system - the high security portal – biometric authentication systems ensure not only that one person gets through at a time, but that it is the right person.

Biometric Authentication Systems in High Security Portals

High security portals combined with biometric authentication systems typically use multi-factor authentication. Usually, they have a card/token scanner at the entrance. When the token has been scanned by the access control system, a door will open allowing you inside the portal. Inside the portal, there will be a biometric reader. This system will individually scan your biometrics, comparing your data to what has been logged on the token read at the first point of access. Our Circlelocks and Circlelock Combi’s come with an internal biometric post, which allows mounting of biometric devices.

Biometric Authentication Systems in Speed Gates

Biometric authentication is not only reserved for the highest levels of security. Using biometrics in access control has more advantages, also in medium security authorisation areas. You may accidentally forget your password or card, but you will never forget your fingerprints. Biometrics cannot easily be recreated or compromised, and biometric devices often offer fast operation that does not hinder throughput levels. That makes it an ideal identifier to use in speed gates. Speed Gates can be placed in the reception area, offering you fast, convenient and secure access to the rest of the building.

There are various ways to integrate biometric authentication systems with speed gates. They include custom pedestals, top-mounted and interior-mounted.
