Biometric Technology enables identification of person depending on intrinsic physical characteristics. There are several parts of the body which are frequently used for biometric identification like fingerprint, face, iris, and palm. Fingerprint will be the one that most favored for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes which render it popular biometric object for example simple to capture, consistent throughout human lifespan and invite quick verification.
Today, fingerprint machine continues to be traditionally used as standard office equipments. Its usage encompasses various purposes. It really is utilized for governing the physical security access, authenticating privilege for particular business process, and also recording time attendance. This post mainly discusses the very last issue, which would be to allow you to choose fingerprint machine as a time attendance recorder. Right here features that you must consider when selecting fingerprint machine:
Kind of Sensor: sensor is an essential section of fingerprint machine. It captures the style of fingerprint prior to being become unique identification number. There’s two most common types of sensors: optical sensor and silicon sensor.
Optical Sensor may be the oldest form of sensor. It’s much easier to implement and comparatively more stable in diverse 70 degrees. It’s performance is going to be highly determined by the clarity in the optical surface. For this reason, when choosing fingerprint machine with optical sensor, you should think about the coated optical sensor. The coat prevents the sensor from being touched directly and maintains the clarity of optical surface.
Silicon Sensor is newer technology, it constructs fingerprint image by mapping pressure or capacitance differences involving the skin as well as the silicon chip. Fractional treatments offers several positive aspects like producing a better fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor are not durable for frequent usage. Consequently, Silicon Sensor isn’t widely used for public usage including time attendance machine which will be accessed a huge selection of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored inside Fingerprint Machine. It is advisable to go with a fingerprint machine which includes fingerprint template at least two times the most employee. By having number of fingerprint template twice the quantity of employee, each employee can register a backup finger if your machine has a problem for identification.
Capacity of Log Buffer: capacity of log buffer is the most of log transactions that can be stored temporarily in the Fingerprint Machine. Time attendance transaction log is normally stored for several days before being downloaded into database sever. Therefore, the proportions of log buffer have to be repeatedly (usually over half a dozen times) bigger quantity of employee.
Identification Speed: identification speed may be the average time necessary for fingerprint machine to recognize someone depending on his or her fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against a unique fingerprint database. A good fingerprint machine should be able to identify a person in less than 1-second.
Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It might wrongly get the fingerprint pattern. There are 2 forms of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rates are the share of machine to allow get the impostors. Meanwhile, False Rejection Minute rates are the share of machine to reject access by authorized user. Fingerprint Machine should have low FRR and FAR. A Standard quality reference for FRR is below 0.1% and then for FAR is below 0.001%.
Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Quite sure helps as well the owner to evaluate productivity of each employee. However, not all fingerprint machines include built-in reporting software, it is very important component of time attendance system. It will eventually give you the give you the master. The quality of fingerprint machine depends on being able to deliver reports that meet the business requirements.
There are numerous models, features, and capabilities of fingerprint machine available in the market nowadays. The most advance and versatile fingerprint machine may be not the most appropriate for particular company’s environment. The best product is one which fits the business enterprise and technical requirements. It means the equipment have to have appropriate technical specification that suits the physical environment and number of users. It has to also deliver valuable information for handling the hr productivity.
