Biometric Technology enables identification of human according to intrinsic physical characteristics. There are several body parts that happen to be widely used for biometric identification such as fingerprint, face, iris, and palm. Fingerprint may be the one that most widely used for identification system. Besides showing unique pattern for each individual, fingerprint also possess other attributes making it popular biometric object such as easy to capture, consistent throughout human lifespan and invite quick verification.
Today, fingerprint machine has been widely used as standard office equipments. Its usage encompasses number of purposes. It’s used for manipulating the physical security access, authenticating privilege for particular business process, and also recording time attendance. This article mainly discusses the last issue, which would be to allow you to choose fingerprint machine as being a time attendance recorder. Several features you have to consider in choosing fingerprint machine:
Sort of Sensor: sensor is an essential a part of fingerprint machine. It captures the image of fingerprint before being transformed into unique identification number. There are 2 most frequent kinds of sensors: optical sensor and silicon sensor.
Optical Sensor could be the oldest sort of sensor. It’s simpler to implement and comparatively more stable in diverse room temperature. Nonetheless it is performance will be highly dependent upon the clarity of the optical surface. For that reason, when selecting fingerprint machine with optical sensor, you should think of 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. Fractional treatments offers many perks like to become a better fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor won’t be durable for frequent usage. Consequently, Silicon Sensor is not widely used for public usage including time attendance machine that’ll be accessed a huge selection of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that can be stored within the Fingerprint Machine. It is advisable to pick a fingerprint machine containing fingerprint template at least twice the maximum amount employee. By having number of fingerprint template twice the volume 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 will be the maximum number of log transactions that could be stored temporarily inside Fingerprint Machine. Time attendance transaction log is generally stored for several days before being downloaded into database sever. Therefore, the capacity of log buffer have to be several times (usually more than five times) greater than level of employee.
Identification Speed: identification speed could be the average time essential to fingerprint machine to identify an individual according to her or his fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its fingerprint database. An excellent fingerprint machine should be able to identify someone inside of 1-second.
Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It could wrongly get the fingerprint pattern. There are two kinds of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the share of machine to allow get the impostors. Meanwhile, False Rejection Rates are the percentage of machine to reject access by authorized user. Fingerprint Machine should have as low as possible 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 can also help the owner to investigate productivity of every employee. However, not all fingerprint machines feature built-in reporting software, it’s very important component of time attendance system. It’s going to provide you with the result to the owner. The quality of fingerprint machine depends on its capability to deliver reports that satisfy the business requirements.
There are many different models, features, and capabilities of fingerprint machine you can purchase nowadays. The most advance and versatile fingerprint machine may be not the most suitable for particular company’s environment. The top technique is one which fits the organization and technical requirements. It implies the device have to have appropriate technical specification which fits the physical environment and quantity of users. It should also deliver valuable information for managing the human resources productivity.
