Biometric Access
Control Systems
Biometric access control systems allow authorised users to verify their identity using a physical characteristic rather than relying solely on a key, access card or fob.
​
Depending on the selected technology, a biometric door entry system may use fingerprint or facial recognition to determine whether somebody has permission to enter a controlled area.
​
For organisations with appropriate security and operational requirements, biometric access control can provide convenient keyless entry while strengthening the link between an individual user and the credential being presented.
​
What Is Biometric Access Control?​
Biometric access control is a security system that uses a person’s unique biological characteristics to verify their identity before allowing access to a building, room or restricted area.
​
Unlike traditional access control, which typically relies on something a user possesses or knows, such as a key fob, access card or PIN, biometric systems use information linked directly to the individual.
​
A typical biometric access control system combines a biometric reader or terminal with an access-control database. User permissions are defined within the system, while access attempts and events can be recorded for monitoring and reporting purposes. The system can also be connected with other security systems where required.
​
When an authorised user presents their biometric credential, the system verifies their identity against the stored information and then grants or denies access according to their assigned permissions.
Keyless Entry Using Biometric Access Control
One of the main practical benefits of biometric access control is that users do not necessarily need to carry a separate access token. Because access is linked directly to the individual, biometrics can also help strengthen security by reducing reliance on credentials that can be lost, shared or misused.
​
This can help reduce problems associated with:
-
Forgotten access cards
-
Lost key fobs
-
Access cards or fobs being passed between users
-
PIN numbers being shared
-
Managing replacement credentials
​
Biometric access control can therefore be suitable for areas where a higher level of security is required and where organisations want greater confidence that the person requesting access is the authorised user.
Types of Biometric Access Control
Biometric access control can use different physical characteristics to verify a user's identity and grant access to authorised areas. The most suitable option will depend on factors such as the level of security required, the environment in which the system is used and how users are expected to interact with the access-control system.
​
Fingerprint Access Control
Fingerprint access control uses a compatible scanner to verify an enrolled user's fingerprint information. It can be applied to individual doors or form part of a wider electronic access-control system, depending on the selected platform and premises.
​​
Facial Recognition Access Control
Facial recognition systems use compatible camera-based technology to verify enrolled users. Because users do not need to physically touch a reader, facial recognition can provide a contactless entry process where this is appropriate for the organisation and selected system.
Where Can Biometric Access Control Be Used?
Biometric systems can be considered for locations where organisations require greater control over the identity of people accessing sensitive areas.
​
Potential applications include:
-
Restricted offices
-
Server and communications rooms
-
Warehouses and stock areas
-
Laboratories
-
Staff-only entrances
-
High-value storage areas
-
Data Centres
​
Biometric Access Control and Data Protection
Using biometrics for access control requires additional consideration because biometric information used to identify individuals is sensitive personal data.
​
Before deployment, organisations should consider how the proposed system fits their data-protection responsibilities, how information will be managed and whether an alternative access method is required. The technology should therefore be selected around both the security objective and the organisation's confirmed operational and data-management requirements.
​
Integrating Biometrics With Wider Access Control
Biometric authentication does not necessarily need to operate as an isolated system. Depending on compatibility, operational needs and security requirements, biometric readers may form part of a wider access-control environment that combines multiple methods of identification and security management.
This can include:
-
Key fobs and access cards, providing a convenient credential-based method for regular users, employees or visitors.
-
PIN access, which can be used as a standalone credential or alongside another form of authentication where additional verification is required.
-
Intercom systems, allowing authorised personnel to communicate with and verify visitors before granting access.
-
CCTV, helping organisations monitor access points and provide additional visual oversight of people entering or leaving a premises.
