Biometric Technology enables identification of person depending on intrinsic physical characteristics. There are several body parts that happen to be commonly used for biometric identification for example fingerprint, face, iris, and palm. Fingerprint may be 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 let quick verification.
Today, fingerprint machine may be trusted as standard office equipments. Its usage encompasses number of purposes. It’s used for managing the physical security access, authenticating privilege for particular business process, and in addition recording time attendance. This post mainly discusses the last issue, which would be to help you to choose fingerprint machine being a time attendance recorder. Right here features that you must consider when choosing fingerprint machine:
Kind of Sensor: sensor is a vital a part of fingerprint machine. It captures the style of fingerprint before being changed into unique identification number. There’s two most frequent forms of sensors: optical sensor and silicon sensor.
Optical Sensor is the oldest sort of sensor. It’s easier to implement and relatively more stable in diverse room temperature. However its performance will probably be highly influenced by the clarity in the optical surface. For that reason, when scouting for 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 relating to the skin and also the silicon chip. This technology offers several positive aspects like creating a more accurate 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 hundreds of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that may be stored inside the Fingerprint Machine. You should choose a fingerprint machine that has fingerprint template at least twice the maximum amount employee. Insurance agencies number of fingerprint template twice the volume of employee, each employee can register a backup finger when the 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 within the Fingerprint Machine. Time attendance transaction log is normally stored stay prior to being downloaded into database sever. Therefore, the ability of log buffer has to be more than once (usually more than 5 times) bigger volume of employee.
Identification Speed: identification speed is the average time necessary for fingerprint machine to distinguish somebody based on his / her fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its very own fingerprint database. An excellent fingerprint machine will be able to identify someone in less than 1-second.
Standard Error: Fingerprint machine cannot work perfectly all the time. It could wrongly find out the fingerprint pattern. There are two types of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rate is the percentage of machine to allow access the impostors. Meanwhile, False Rejection Minute rates are the share of machine to reject access by authorized user. Fingerprint Machine really should have as low as possible FRR and a lot. An ordinary quality reference for FRR is below 0.1% as well as 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 dog owner to investigate productivity of each employee. However, not all fingerprint machines include built-in reporting software, it is vital portion of time attendance system. It will eventually give you the give you the property owner. The standard of fingerprint machine is determined by its capacity to deliver reports that match the business requirements.
There are several models, features, and capabilities of fingerprint machine available for sale nowadays. The most advance and versatile fingerprint machine very can be not the most appropriate for particular company’s environment. The best technique is one that fits the business and technical requirements. It implies the device have to have appropriate technical specification that matches the physical environment and quantity of users. It must also deliver valuable information for managing the human resources productivity.
