    Biometric Technology enables identification of person based on intrinsic physical characteristics. There are several limbs which are frequently used for biometric identification for example fingerprint, face, iris, and palm. Fingerprint could be the the one that hottest for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes that make it popular biometric object including very easy to capture, consistent throughout human lifespan and invite quick verification.

    Today, fingerprint machine may be popular as standard office equipments. Its usage encompasses variety of purposes. It’s employed for governing the physical security access, authenticating privilege for particular business process, plus recording time attendance. This article mainly discusses the very last issue, which would be to help you to choose fingerprint machine as being a time attendance recorder. Right here features that you need to consider when scouting for fingerprint machine:

    Form of Sensor: sensor is the most important a part of fingerprint machine. It captures the look of fingerprint prior to being become unique identification number. There are 2 most typical kinds of sensors: optical sensor and silicon sensor.

    Optical Sensor is the oldest type of sensor. It is better to implement and comparatively more stable in diverse room temperature. However its performance will probably be highly dependent upon the clarity in the optical surface. Because of this, when selecting fingerprint machine with optical sensor, you should consider 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. Fraxel treatments offers several advantages like producing a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor won’t be durable for frequent usage. Consequently, Silicon Sensor just isn’t widely used for public usage such as time attendance machine that will be accessed a huge selection of times everyday.

    Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image that may be stored inside Fingerprint Machine. You need to select a fingerprint machine that has fingerprint template twice the maximum amount employee. Insurance firms amount of fingerprint template twice the quantity 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 is the maximum number of log transactions that could be stored temporarily inside the Fingerprint Machine. Time attendance transaction log is generally stored for a few days prior to being downloaded into database sever. Therefore, the capability of log buffer should be more than once (usually a lot more than five times) bigger than quantity of employee.

    Identification Speed: identification speed is the average time necessary for fingerprint machine to spot someone depending on his or her fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its fingerprint database. A great fingerprint machine can identify somebody in under 1-second.

    Standard Error: Fingerprint machine cannot work perfectly all the time. It could wrongly identify the fingerprint pattern. There’s two varieties 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 Rates are the share of machine to reject access by authorized user. Fingerprint Machine must have low FRR and. 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 also helps the dog owner to evaluate productivity of every employee. But not all fingerprint machines come with built-in reporting software, it is vital part of time attendance system. It’s going to provide you with the cause the master. The caliber of fingerprint machine is dependent upon its ability to deliver reports that fulfill the business requirements.

    There are many different models, features, and capabilities of fingerprint machine available in the market nowadays. The most advance and versatile fingerprint machine very can be not the best option for particular company’s environment. The top method is one which fits the company and technical requirements. It means the equipment have to have appropriate technical specification that matches the physical environment and number of users. It should also deliver valuable information for managing the human resources productivity.
