    Biometric Technology enables identification of human depending on intrinsic physical characteristics. There are many body parts that happen to be popular for biometric identification for example fingerprint, face, iris, and palm. Fingerprint is the the one which most favored for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes that make it popular biometric object including easy to capture, consistent throughout human lifespan and invite quick verification.

    Today, fingerprint machine may be traditionally used as standard office equipments. Its usage encompasses number of purposes. It is useful for manipulating the physical security access, authenticating privilege for particular business process, and in addition recording time attendance. This post mainly discusses the very last issue, which is to help you to choose fingerprint machine as being a time attendance recorder. Here are several features you need to consider when selecting fingerprint machine:

    Sort of Sensor: sensor is the central part of fingerprint machine. It captures the picture of fingerprint prior to being transformed into unique identification number. There’s two most frequent types of sensors: optical sensor and silicon sensor.

    Optical Sensor may be the oldest form of sensor. It’s better to implement and comparatively more stable in diverse room temperature. Nonetheless it is performance will be highly dependent upon 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 between your skin and the silicon chip. Fraxel treatments offers several positive aspects like producing 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 is not popular for public usage like time attendance machine that’ll be accessed countless times everyday.

    Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored inside the Fingerprint Machine. It is advisable to pick a fingerprint machine containing fingerprint template at least 2 times the maximum amount of employee. Insurance firms number of fingerprint template twice how much employee, each employee can register a backup finger if the machine carries a problem for identification.

    Capacity of Log Buffer: capacity of log buffer could be the maximum number of log transactions that may be stored temporarily in the Fingerprint Machine. Time attendance transaction log is normally stored stay prior to being downloaded into database sever. Therefore, the capacity of log buffer should be several times (usually more than more) greater than quantity of employee.

    Identification Speed: identification speed is the average time required by fingerprint machine to identify somebody depending on his or her fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its very own fingerprint database. A great fingerprint machine should be able to identify a person in less than 1-second.

    Standard Error: Fingerprint machine cannot work perfectly continuously. It may wrongly get the fingerprint pattern. There are two varieties of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the proportion of machine to grant access the impostors. Meanwhile, False Rejection Rates are the share of machine to reject access by authorized user. Fingerprint Machine needs to have as small as possible 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. Many can also help the master to evaluate productivity of each and every employee. But not all fingerprint machines come with built-in reporting software, it’s very important element of time attendance system. It will eventually deliver the lead to the owner. The grade of fingerprint machine depends on its capability to deliver reports that fulfill the business requirements.

    There are several models, features, and capabilities of fingerprint machine you can purchase nowadays. Probably the most advance and versatile fingerprint machine may be not the most suitable for particular company’s environment. The very best product is one that fits the organization and technical requirements. This means the equipment have to have appropriate technical specification that matches the physical environment and quantity of users. It should also deliver valuable information for handling the hr productivity.
