    Biometric Technology enables identification of person based on intrinsic physical characteristics. There are numerous parts of the body that happen to be frequently used for biometric identification including fingerprint, face, iris, and palm. Fingerprint could be the the one which most in-demand for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes that make it popular biometric object for example an easy task to capture, consistent throughout human lifespan and invite quick verification.

    Today, fingerprint machine continues to be popular as standard office equipments. Its usage encompasses variety of purposes. It’s useful for managing 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 assist you to choose fingerprint machine like a time attendance recorder. Below are some features that you need to consider in choosing fingerprint machine:

    Type of Sensor: sensor is an essential section of fingerprint machine. It captures the style of fingerprint prior to being transformed into unique identification number. There are 2 most typical varieties of sensors: optical sensor and silicon sensor.

    Optical Sensor will be the oldest sort of sensor. It’s simpler to implement and comparatively more stable in diverse 70 degrees. However its performance is going to be highly dependent on the clarity with the optical surface. Because of this, in choosing fingerprint machine with optical sensor, you should look at 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 involving the skin along with the silicon chip. Fraxel treatments offers several positive aspects like making 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 is not commonly used for public usage for example time attendance machine that’ll be accessed a huge selection of times everyday.

    Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that can be stored from the Fingerprint Machine. Make sure you select a fingerprint machine containing fingerprint template at least two times the most employee. With quantity of fingerprint template twice the amount of employee, each employee can register a backup finger if the machine carries a problem for identification.

    Capacity of Log Buffer: capacity of log buffer will be the most of log transactions that could be stored temporarily in the Fingerprint Machine. Time attendance transaction log is often stored for a few days prior to being downloaded into database sever. Therefore, the capability of log buffer have to be repeatedly (usually more than more) bigger amount of employee.

    Identification Speed: identification speed could be the average time essential to fingerprint machine to distinguish somebody depending on his / her fingerprint pattern. The method comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against a unique fingerprint database. An excellent fingerprint machine can identify someone in under 1-second.

    Standard Error: Fingerprint machine cannot work perfectly all the time. It may wrongly know the fingerprint pattern. There’s 2 forms of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the percentage of machine to allow connect to the impostors. Meanwhile, False Rejection Minute rates are the proportion of machine to reject access by authorized user. Fingerprint Machine must have as small as possible FRR and. An ordinary quality reference for FRR is below 0.1% and then for FAR is below 0.001%.

    Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Quite sure can also help the owner to analyze productivity of each employee. However, not all fingerprint machines feature built-in reporting software, it is crucial part of time attendance system. It will provide you with the lead to the master. The grade of fingerprint machine is dependent upon being able to deliver reports that match the business requirements.

    There are numerous models, features, and capabilities of fingerprint machine available for sale nowadays. Essentially the most advance and versatile fingerprint machine very can be not the best option for particular company’s environment. The top technique is one that fits the business enterprise and technical requirements. This means your machine should have appropriate technical specification which fits the physical environment and quantity of users. It requires to also deliver valuable information for managing the human resources productivity.
