Tips for Choosing A Fingerprint Time Attendance System

Biometric Technology enables identification of human determined by intrinsic physical characteristics. There are many parts of the body that happen to be widely used for biometric identification like fingerprint, face, iris, and palm. Fingerprint may be the one which hottest for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes making it popular biometric object such as an easy task to capture, consistent throughout human lifespan and enable quick verification.

Today, fingerprint machine may be widely used as standard office equipments. Its usage encompasses number of purposes. It's useful for manipulating the physical security access, authenticating privilege for particular business process, and also recording time attendance. This post mainly discusses the past issue, which would be to assist you to choose fingerprint machine being a time attendance recorder. Right here features you have to consider when selecting fingerprint machine:

Type of Sensor: sensor is a vital section of fingerprint machine. It captures the image of fingerprint prior to being converted into unique identification number. There's 2 most typical varieties of sensors: optical sensor and silicon sensor.
Optical Sensor will be the oldest type of sensor. It really is much easier to implement and comparatively more stable in diverse 70 degrees. Nonetheless its performance will probably be highly determined by the clarity of the optical surface. That is why, when choosing fingerprint machine with optical sensor, you should look at 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 laser treatments offers several positive aspects like to become a better 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 just isn't commonly used for public usage such as time attendance machine that is to be accessed hundreds of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored from the Fingerprint Machine. You should select a fingerprint machine containing fingerprint template at least 2 times the maximum amount employee. Insurance firms amount of fingerprint template twice the volume of employee, each employee can register a backup finger if your machine carries a problem for identification.
Capacity of Log Buffer: capacity of log buffer may be the maximum number of log transactions that could be stored temporarily inside Fingerprint Machine. Time attendance transaction log is usually stored for several days before being downloaded into database sever. Therefore, the proportions of log buffer has to be repeatedly (usually more than more) greater than amount of employee.
Identification Speed: identification speed may be the average time essential to fingerprint machine to identify a person according to his / her fingerprint pattern. The procedure comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against a unique fingerprint database. An excellent fingerprint machine should be able to identify somebody inside of 1-second.
Standard Error: Fingerprint machine cannot work perfectly continuously. It could wrongly find out the fingerprint pattern. There are two varieties of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rates are the percentage of machine to grant connect to the impostors.
