Security and accurate access control and time and attendance tracking are the main reasons behind updating your existing systems to modern access control devices.
Biometrics by virtue of their identifying methods obviate the need for pins, passwords or physical identifiers such as id cards or tokens. This immediately secures your company by disallowing members from sharing information between themselves such as the aforementioned passwords or cards in order to access secure areas or clock in for each other when absent. Besides the immediate security boost and increase in profits from accurate time tracking the system aids in the automation of many key HR processes such as payroll and scheduling.
So how do biometrics work in any case? It might surprise you that they are only minorly different from card swiping security systems in that, much in the way a security card’s identifier is stored against an employees name in a database, so too is the employee’s fingerprint, facial topography or vascular map which is just abstracted to a unique identifier that is then stored against the employee’s name in the database. The employee is then assigned rights and privileges in the software which controls their ability to access areas as well as track their attendance in your employee data management application.
The methods for capturing this biometric data vary greatly in their function. At one end of the spectrum we have the pervasive fingerprint scanner to DNA recognition at the other. The factors a company needs to consider when integrating a new biometric system are:
Universality: the method of capturing biometric data should have the broadest application across your workforce. You may have staff who do not have a full complement of digits or perhaps eye injuries that will impact your ability to incorporate them into your system if you are using fingerprint or iris scanning.
Uniqueness: The implemented system must be of sufficient quality to accurately discern each employee’s scanned feature and not conflate identifiers resulting in false positives.
Permanence: Equally, the system must be capturing biometrics that have a sufficient degree of expected permanence, Voice control, for example can be a problem with staff suffering from laryngitis or advanced colds.
Collectability: When implementing the system, the method for collecting the biometric data for the initial setup should be planned well ahead of time . Questions such as how and where to collect data should be taken into account as first scans can take multiple attempts and it is important to consider how this affects your production, further complexity can arrive if, for example, you are attempting to collect facial recognition data in an environment with low or excessive light or perhaps voice prints in an area with excessive noise.
Performance: Using high level biometrics such as DNA recognition can impact your productivity as results can take up to ten minutes, depending on hardware, for accurate results. You may find that fingerprints or facial recognition are more appropriate for your environment.
Circumvention: Biometrics that cannot be defeated easily, such as through holding up portrait photos in front of low quality facial recognition scanners, are key in choosing the right system for your workplace. Always insist on the best quality and ensure that tests are carried out before you sign off on any system.
Finally it is important to ensure that your access points and hardware are placed in controlled environments so that conditions are always the same when data is collected. This will ensure that information is always correct and samples have a high degree of similarity when scanned.
