Methods for Selecting a Fingerprint Time Attendance System
Biometric Technology enables identification of person depending on intrinsic physical characteristics. There are several areas of the body which are widely used for biometric identification like fingerprint, face, iris, and palm. Fingerprint will be the the one which most favored for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes which make it popular biometric object like easy to capture, consistent throughout human lifespan and give quick verification.
Today, fingerprint machine continues to be widely used as standard office equipments. Its usage encompasses number of purposes. It's used for manipulating the physical security access, authenticating privilege for particular business process, and also recording time attendance. This article mainly discusses the past issue, which would be to help you to choose fingerprint machine like a time attendance recorder. Below are some features you need to consider when scouting for fingerprint machine:
Type of Sensor: sensor is the most important part of fingerprint machine. It captures the image of fingerprint before being transformed into unique identification number. There are two most typical kinds of sensors: optical sensor and silicon sensor.
Optical Sensor could be the oldest kind of sensor. It can be easier to implement and comparatively more stable in diverse 70 degrees. Nonetheless its performance is going to be highly dependent upon the clarity with the optical surface. Because of this, when scouting for fingerprint machine with optical sensor, you should think of 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 along with the silicon chip. This technology offers several positive aspects like making a better 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 just not popular for public usage like time attendance machine that will be accessed numerous times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image which can be stored from the Fingerprint Machine. It is advisable to pick a fingerprint machine which includes fingerprint template at least twice the maximum amount of employee. Insurance agencies 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 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 before being downloaded into database sever. Therefore, the ability of log buffer should be repeatedly (usually greater than more) bigger amount of employee.
Identification Speed: identification speed is the average time necessary for fingerprint machine to spot a person depending on her or his fingerprint pattern. The procedure comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its fingerprint database. A fantastic fingerprint machine will be able to identify an individual in under 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 share of machine to allow connect to the impostors. Meanwhile, False Rejection Minute rates are the percentage of machine to reject access by authorized user. Fingerprint Machine really should have to a minimum FRR and. A regular quality reference for FRR is below 0.1% as well as for FAR is below 0.001%.
Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Many helps as well the master to analyze productivity of each and every employee. However, not all fingerprint machines come with built-in reporting software, it is vital component of time attendance system. It is going to provide the lead to the master. The grade of fingerprint machine is determined by being able to deliver reports that fulfill the business requirements.
There are several models, features, and capabilities of fingerprint machine available for sale nowadays. The most advance and versatile fingerprint machine very can be not the most suitable for particular company's environment. The top method is one which fits the business and technical requirements. This means the device must have appropriate technical specification which fits the physical environment and variety of users. It has to also deliver valuable information for managing the human resources productivity.
