    Biometric Technology enables identification of person determined by intrinsic physical characteristics. There are many parts of the body that happen to be commonly used for biometric identification including fingerprint, face, iris, and palm. Fingerprint could be the one that most widely used for identification system. Besides showing unique pattern for each individual, 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 has been traditionally used as standard office equipments. Its usage encompasses variety of purposes. It’s utilized for manipulating the physical security access, authenticating privilege for particular business process, as well as recording time attendance. This article mainly discusses the last issue, which would be to help you to choose fingerprint machine like a time attendance recorder. Several features you have to consider when selecting fingerprint machine:

    Form of Sensor: sensor is a vital portion of fingerprint machine. It captures the image of fingerprint prior to being transformed into unique identification number. There’s two most common forms of sensors: optical sensor and silicon sensor.

    Optical Sensor may be the oldest kind of sensor. It really is better to implement and relatively more stable in diverse 70 degrees. However its performance will probably be highly dependent on the clarity from the optical surface. That is why, 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 between your skin and the silicon chip. This technology offers several advantages like to become a more accurate fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor will not be durable for frequent usage. Consequently, Silicon Sensor is not widely used for public usage for example time attendance machine that is to be accessed countless times everyday.

    Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored from the Fingerprint Machine. You need to pick a fingerprint machine that has fingerprint template at least twice the most employee. With quantity of fingerprint template twice the amount of employee, each employee can register a backup finger if your machine includes a problem for identification.

    Capacity of Log Buffer: capacity of log buffer may be the most of log transactions that could be stored temporarily within the Fingerprint Machine. Time attendance transaction log is generally stored during their visit prior to being downloaded into database sever. Therefore, the capability of log buffer should be many times (usually over half a dozen times) greater than level of employee.

    Identification Speed: identification speed will be the average time necessary for fingerprint machine to spot somebody determined by their fingerprint pattern. The method comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its very own fingerprint database. A fantastic fingerprint machine can identify a person within just 1-second.

    Standard Error: Fingerprint machine cannot work perfectly all the time. It could wrongly know the fingerprint pattern. There’s 2 types of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rates are the percentage of machine to grant get the impostors. Meanwhile, False Rejection Rates are the proportion of machine to reject access by authorized user. Fingerprint Machine should have as low as possible FRR and FAR. A typical 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. This software can also help the owner to evaluate productivity of each and every employee. While not all fingerprint machines have built-in reporting software, it is vital element of time attendance system. It is going to provide the result to the dog owner. The quality of fingerprint machine depends upon its ability to deliver reports that match the business requirements.

    There are several models, features, and capabilities of fingerprint machine you can find nowadays. The most advance and versatile fingerprint machine may be not the most suitable for particular company’s environment. The best product is one that fits the business and technical requirements. This means the equipment must have appropriate technical specification which fits the physical environment and amount of users. It requires to also deliver valuable information for handling the recruiting productivity.
