Biometric Access Control uses human characteristics such as fingerprints as a form of identification to grant access to authorised individuals.
The purpose of a Biometric system is to restrict access to unauthorised individuals, enhancing site security. Biometric access control can also be used for time and attendance purposes, to ensure that employees are only paid for the hours they work. Which can dramatically improve human resources management such as overtime, attendance and working pattern rules.
These systems can be integrated into existing systems and the accuracy and inimitability of the system make it an attractive option for organisations.
Through advanced imaging technologies, biometric fingerprint readers can accurately capture fingerprint data. Most Biometric systems use multispectral imaging (MSI) technology to capture fingerprint readings. This method uses various lights to register between 1-1000 reference points to create a digital image.
Once a fingerprint has been applied to the reader, the system will search its database for a matching fingerprint in order to grant the user access.
The readers are able to successfully scan fingerprints in harsh environments, as their heat and humidity sensors allow the system to work in temperatures as low as -20°C and as high as 70°C. Some readers are also specifically designed for external areas and can scan a fingerprint through levels of common environmental substances such as dust, oil and dirt are present.
Biometric systems are also equipped with liveness detection, which helps identify fake fingerprints. The technology is capable of differentiating live human fingerprints and false fingerprints replicated by synthetic materials.
