    Biometric Technology enables identification of human according to intrinsic physical characteristics. There are several parts of the body that happen to be popular for biometric identification for example fingerprint, face, iris, and palm. Fingerprint may be the one which most in-demand for identification system. Besides showing unique pattern for each individual, fingerprint also possess other attributes which render it popular biometric object like simple to capture, consistent throughout human lifespan and invite quick verification.

    Today, fingerprint machine has been trusted as standard office equipments. Its usage encompasses variety of purposes. It’s useful 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 assist you to choose fingerprint machine being a time attendance recorder. Here are several features that you must consider when choosing fingerprint machine:

    Form of Sensor: sensor is a vital portion of fingerprint machine. It captures the picture of fingerprint before being become unique identification number. There’s two most popular forms of sensors: optical sensor and silicon sensor.

    Optical Sensor is the oldest type of sensor. It really is easier to implement and relatively more stable in diverse room temperature. Nonetheless its performance will be highly dependent on the clarity in the optical surface. Because of this, in 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 between the skin and the silicon chip. This technology offers several positive aspects like making a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor will never be durable for frequent usage. Consequently, Silicon Sensor just isn’t widely used for public usage such as time attendance machine that is to be accessed numerous 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 choose a fingerprint machine which includes fingerprint template at least two times the maximum amount employee. With amount of fingerprint template twice how much employee, each employee can register a backup finger if your machine includes a problem for identification.

    Capacity of Log Buffer: capacity of log buffer could be the maximum number of log transactions which can be stored temporarily inside the Fingerprint Machine. Time attendance transaction log is usually stored for several days prior to being downloaded into database sever. Therefore, the capability of log buffer should be many times (usually over five times) bigger than quantity of employee.

    Identification Speed: identification speed may be the average time essential to fingerprint machine to recognize somebody determined by her or his fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its fingerprint database. A good fingerprint machine will be able to identify someone in less than 1-second.

    Standard Error: Fingerprint machine cannot work perfectly on a regular basis. 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 connect to the impostors. Meanwhile, False Rejection Minute rates are the percentage of machine to reject access by authorized user. Fingerprint Machine must have to a minimum FRR and a lot. A typical quality reference for FRR is below 0.1% as well as FAR is below 0.001%.

    Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Many likewise helps the owner to evaluate productivity of each one employee. While not all fingerprint machines have built-in reporting software, it is vital portion of time attendance system. It will eventually provide the cause the master. The grade of fingerprint machine depends upon being able to deliver reports that satisfy the business requirements.

    There are numerous models, features, and capabilities of fingerprint machine available in the market nowadays. One of the most advance and versatile fingerprint machine very can be not the most suitable for particular company’s environment. The best product is the one which fits the business enterprise and technical requirements. This means the equipment must have appropriate technical specification which fits the physical environment and number of users. It requires to also deliver valuable information for managing the human resources productivity.
