    Biometric Technology enables identification of person determined by intrinsic physical characteristics. There are several limbs that are popular for biometric identification for example fingerprint, face, iris, and palm. Fingerprint could be the the one which most favored for identification system. Besides showing unique pattern for each individual, fingerprint also possess other attributes which render it popular biometric object for example very easy to capture, consistent throughout human lifespan and enable quick verification.

    Today, fingerprint machine continues to be popular as standard office equipments. Its usage encompasses variety of purposes. It can be employed for controlling the physical security access, authenticating privilege for particular business process, as well as recording time attendance. This short article mainly discusses the final issue, which is to assist you to choose fingerprint machine being a time attendance recorder. Right here features that you must consider when scouting for fingerprint machine:

    Form of Sensor: sensor is the central a part of fingerprint machine. It captures the image of fingerprint prior to being changed into unique identification number. There are 2 most typical types of sensors: optical sensor and silicon sensor.

    Optical Sensor will be the oldest kind of sensor. It really is better to implement and comparatively more stable in diverse 70 degrees. It’s performance will probably be highly determined by the clarity from the optical surface. Because of this, when selecting 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 relating to the skin and the silicon chip. Fractional treatments offers many perks like producing 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 popular 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 most of fingerprint image that could be stored inside Fingerprint Machine. Make sure you select a fingerprint machine containing fingerprint template at least two times the most employee. Insurance agencies quantity of fingerprint template twice the quantity of employee, each employee can register a backup finger when the machine has a problem for identification.

    Capacity of Log Buffer: capacity of log buffer is the most of log transactions that can be stored temporarily within the Fingerprint Machine. Time attendance transaction log is often stored stay prior to being downloaded into database sever. Therefore, the capability of log buffer has to be several times (usually a lot more than half a dozen times) larger than level of employee.

    Identification Speed: identification speed could be the average time required by fingerprint machine to recognize an individual based on his / her fingerprint pattern. The method comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. A fantastic fingerprint machine are able to identify a person in less than 1-second.

    Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It may well wrongly find out the fingerprint pattern. There are 2 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 share of machine to reject access by authorized user. Fingerprint Machine should have to a minimum FRR and a lot. A Standard 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. This software likewise helps the property owner to research productivity of every employee. However, not all fingerprint machines include built-in reporting software, it is very important element of time attendance system. It’s going to provide the lead to the owner. The quality of fingerprint machine depends upon its ability to deliver reports that match the business requirements.

    There are various models, features, and capabilities of fingerprint machine you can find nowadays. One of the most advance and versatile fingerprint machine may be not the most appropriate for particular company’s environment. The very best method is one that fits the business and technical requirements. It indicates the device have to have appropriate technical specification that fits the physical environment and amount of users. It must also deliver valuable information for managing the recruiting productivity.
