    Biometric Technology enables identification of person based on intrinsic physical characteristics. There are several parts of the body that are widely used for biometric identification for example fingerprint, face, iris, and palm. Fingerprint may be the one which hottest for identification system. Besides showing unique pattern for each individual, fingerprint also possess other attributes which render it popular biometric object for example simple to capture, consistent throughout human lifespan and give quick verification.

    Today, fingerprint machine may be popular as standard office equipments. Its usage encompasses variety of purposes. It is employed 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 is to allow you to choose fingerprint machine as a time attendance recorder. Here are several features that you need to consider in choosing fingerprint machine:

    Kind of Sensor: sensor is an essential a part of fingerprint machine. It captures the style of fingerprint prior to being changed into unique identification number. There are two most typical varieties of sensors: optical sensor and silicon sensor.

    Optical Sensor could be the oldest type of sensor. It can be better to implement and comparatively more stable in diverse room temperature. Nonetheless its performance will be highly dependent upon the clarity in the optical surface. That is why, 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 the silicon chip. Fractional treatments offers several advantages like making a better 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 isn’t widely used for public usage like time attendance machine that will be accessed countless times everyday.

    Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image that may be stored inside Fingerprint Machine. You should select a fingerprint machine which has fingerprint template at least twice the most employee. With number of fingerprint template twice the volume of employee, each employee can register a backup finger if your machine has a problem for identification.

    Capacity of Log Buffer: capacity of log buffer could be the maximum number of log transactions that could be stored temporarily in the Fingerprint Machine. Time attendance transaction log is generally stored for several days before being downloaded into database sever. Therefore, the capability of log buffer has to be several times (usually more than half a dozen times) larger than quantity of employee.

    Identification Speed: identification speed could be the average time essential to fingerprint machine to spot an individual according to his or her fingerprint pattern. The process comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its very own fingerprint database. A good fingerprint machine will be able to identify an individual in under 1-second.

    Standard Error: Fingerprint machine cannot work perfectly all the time. It may wrongly get the fingerprint pattern. There’s 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 Rate is the share of machine to reject access by authorized user. Fingerprint Machine needs to have low FRR and a lot. A typical 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 can also help the master to analyze productivity of each employee. However, not all fingerprint machines have built-in reporting software, it is vital portion of time attendance system. It will eventually give you the cause the master. The quality of fingerprint machine is dependent upon its capability to deliver reports that meet 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 very can be not the most appropriate for particular company’s environment. The very best technique is one which fits the company and technical requirements. It indicates your machine will need to have appropriate technical specification which fits the physical environment and quantity of users. It has to also deliver valuable information for handling the recruiting productivity.
