Tricks for Deciding on a Fingerprint Time Attendance System
Biometric Technology enables identification of person depending on intrinsic physical characteristics. There are numerous limbs that happen to be commonly used for biometric identification including fingerprint, face, iris, and palm. Fingerprint could be the the one which most favored for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes making it popular biometric object like an easy task to capture, consistent throughout human lifespan and enable quick verification.
Today, fingerprint machine has become traditionally used as standard office equipments. Its usage encompasses selection of purposes. It is utilized for manipulating the physical security access, authenticating privilege for particular business process, and in addition recording time attendance. This informative article mainly discusses the last issue, which would be to help you to choose fingerprint machine as being a time attendance recorder. Several features you need to consider in choosing fingerprint machine:
Kind of Sensor: sensor is the central portion of fingerprint machine. It captures the style of fingerprint prior to being become unique identification number. There are two most common types of sensors: optical sensor and silicon sensor.
Optical Sensor may be the oldest sort of sensor. It can be simpler to implement and comparatively more stable in diverse room temperature. Nonetheless its performance will probably be highly determined by the clarity in the optical surface. That is why, 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 between the skin and also the silicon chip. Fractional treatments offers several advantages like creating a more accurate 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 frequently used for public usage such as time attendance machine that'll be accessed hundreds of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored within the Fingerprint Machine. Make sure you choose a fingerprint machine that has fingerprint template at least 2 times the most employee. Insurance agencies quantity of fingerprint template twice how much employee, each employee can register a backup finger if your machine has a problem for identification.
Capacity of Log Buffer: capacity of log buffer will be the most of log transactions that could be stored temporarily inside the Fingerprint Machine. Time attendance transaction log is generally stored during their visit prior to being downloaded into database sever. Therefore, the capacity of log buffer should be repeatedly (usually greater than 5 times) greater than level of employee.
Identification Speed: identification speed is the average time necessary for fingerprint machine to identify an individual depending on his / her fingerprint pattern. The procedure comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its very own fingerprint database. A great fingerprint machine will be able to identify somebody in under 1-second.
Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It may wrongly get the fingerprint pattern. There are two forms of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the share of machine to allow get the impostors. Meanwhile, False Rejection Rates are the share of machine to reject access by authorized user. Fingerprint Machine should have as small as possible FRR and FAR. A regular 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. This software also helps the master to investigate productivity of every employee. However, not all fingerprint machines have built-in reporting software, it is very important portion of time attendance system. It will provide you with the lead to the property owner. The caliber of fingerprint machine is dependent upon its capability to deliver reports that meet the business requirements.
There are several models, features, and capabilities of fingerprint machine available for sale nowadays. Probably the most advance and versatile fingerprint machine may be not the most suitable for particular company's environment. The top strategy is one that fits the organization and technical requirements. It implies the equipment should have appropriate technical specification which fits the physical environment and amount of users. It should also deliver valuable information for handling the recruiting productivity.
