Tips for Selecting a Fingerprint Time Attendance System
from web site
Biometric Technology enables identification of human depending on intrinsic physical characteristics. There are numerous body parts that happen to be popular for biometric identification including fingerprint, face, iris, and palm. Fingerprint is the the one which most widely used for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes which render it popular biometric object like very easy to capture, consistent throughout human lifespan and enable quick verification.
Today, fingerprint machine may be widely used as standard office equipments. Its usage encompasses variety of purposes. It can be used for managing the physical security access, authenticating privilege for particular business process, plus recording time attendance. This article mainly discusses the past issue, which would be to enable you to choose fingerprint machine as being a time attendance recorder. Right here features that you must consider when selecting fingerprint machine:
Kind of Sensor: sensor is a vital part of fingerprint machine. It captures the look of fingerprint prior to being transformed into unique identification number. There's two most frequent forms of sensors: optical sensor and silicon sensor.
Optical Sensor is the oldest form of sensor. It really is easier to implement and comparatively more stable in diverse room temperature. Nonetheless its performance will be highly dependent on the clarity with the optical surface. Because of this, in choosing fingerprint machine with optical sensor, you should consider 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 between the skin and also the silicon chip. Fraxel treatments offers many perks like to become a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor will not be durable for frequent usage. Consequently, Silicon Sensor isn't widely used for public usage for example time attendance machine that is to be accessed countless times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image that may be stored inside the Fingerprint Machine. You should go with a fingerprint machine that has fingerprint template at least twice the most employee. Insurance agencies quantity of fingerprint template twice the quantity of employee, each employee can register a backup finger if your machine features a problem for identification.
Capacity of Log Buffer: capacity of log buffer is the most of log transactions that can be stored temporarily inside Fingerprint Machine. Time attendance transaction log is normally stored during their visit prior to being downloaded into database sever. Therefore, the proportions of log buffer should be more than once (usually more than more) bigger than volume of employee.
Identification Speed: identification speed may be the average time necessary for fingerprint machine to identify a person according to their fingerprint pattern. The procedure comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. An excellent fingerprint machine should be able to identify a person in under 1-second.
Standard Error: Fingerprint machine cannot work perfectly continuously. It may well wrongly know the fingerprint pattern. There's two varieties of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rate is the share of machine to grant get the impostors. Meanwhile, False Rejection Rates are the proportion of machine to reject access by authorized user. Fingerprint Machine should have low FRR and. An ordinary quality reference for FRR is below 0.1% and for FAR is below 0.001%.
Reporting Software: reporting software aggregates the transaction logs and reports in readable format. This software likewise helps the dog owner to research productivity of each one employee. However, not all fingerprint machines come with built-in reporting software, it is crucial element of time attendance system. It will give you the lead to the owner. The grade of fingerprint machine is determined by being able to deliver reports that satisfy the business requirements.
There are several models, features, and capabilities of fingerprint machine available for sale nowadays. Probably the most advance and versatile fingerprint machine may be not the most suitable for particular company's environment. The top method is the one which fits the company and technical requirements. It implies your machine must have appropriate technical specification which fits the physical environment and number of users. It should also deliver valuable information for handling the hours productivity.
