    Biometric Technology enables identification of human determined by intrinsic physical characteristics. There are numerous body parts which are widely used for biometric identification including fingerprint, face, iris, and palm. Fingerprint is the the one which hottest for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes which render it popular biometric object such as easy to capture, consistent throughout human lifespan and invite quick verification.

    Today, fingerprint machine continues to be widely used as standard office equipments. Its usage encompasses various purposes. It really is useful for manipulating the physical security access, authenticating privilege for particular business process, and also recording time attendance. This informative article mainly discusses the last issue, which is to help you to choose fingerprint machine being a time attendance recorder. Right here features that you need to consider when choosing fingerprint machine:

    Sort of Sensor: sensor is a vital a part of fingerprint machine. It captures the look of fingerprint before being changed into unique identification number. There are two most frequent varieties of sensors: optical sensor and silicon sensor.

    Optical Sensor will be the oldest form of sensor. It can be much easier to implement and comparatively more stable in diverse room temperature. However its performance will be highly dependent upon the clarity from the optical surface. Because of this, when choosing 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 as well as the silicon chip. Fractional laser treatments offers many perks like to become a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor are not 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 can be stored inside Fingerprint Machine. Make sure you go with a fingerprint machine which has fingerprint template at least two times the maximum amount employee. By having quantity of fingerprint template twice the amount of employee, each employee can register a backup finger if the machine includes a problem for identification.

    Capacity of Log Buffer: capacity of log buffer is the most of log transactions which can be stored temporarily within the Fingerprint Machine. Time attendance transaction log is generally stored stay before being downloaded into database sever. Therefore, the ability of log buffer have to be many times (usually over more) bigger than amount of employee.

    Identification Speed: identification speed could be the average time essential to fingerprint machine to spot a person based on his / her fingerprint pattern. The method comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. An excellent fingerprint machine should be able to identify somebody within just 1-second.

    Standard Error: Fingerprint machine cannot work perfectly all the time. It could wrongly find out the fingerprint pattern. There’s two varieties of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the share of machine to grant get the impostors. Meanwhile, False Rejection Rate is the share of machine to reject access by authorized user. Fingerprint Machine needs to have as low as possible FRR and. A regular 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. Many also helps the dog owner to investigate productivity of each employee. While not all fingerprint machines feature built-in reporting software, it’s very important portion of time attendance system. It is going to give you the give you the owner. The caliber of fingerprint machine is determined by being able to deliver reports that meet the business requirements.

    There are various models, features, and capabilities of fingerprint machine you can find nowadays. Essentially the most advance and versatile fingerprint machine very can be not the best choice for particular company’s environment. The very best strategy is one that fits the business and technical requirements. This means the equipment should have appropriate technical specification that suits the physical environment and variety of users. It requires to also deliver valuable information for managing the hr productivity.
