Biometric Technology enables identification of human determined by intrinsic physical characteristics. There are numerous body parts that happen to be commonly used for biometric identification like fingerprint, face, iris, and palm. Fingerprint is the one that most widely used for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes which make it popular biometric object such as simple to capture, consistent throughout human lifespan and invite quick verification.
Today, fingerprint machine continues to be popular as standard office equipments. Its usage encompasses number of purposes. It is employed for governing the physical security access, authenticating privilege for particular business process, plus recording time attendance. This short article mainly discusses the final issue, which would be to enable you to choose fingerprint machine being a time attendance recorder. Several features you have to consider when choosing fingerprint machine:
Kind of Sensor: sensor is the central section of fingerprint machine. It captures the picture of fingerprint prior to being changed into unique identification number. There’s two most common kinds of sensors: optical sensor and silicon sensor.
Optical Sensor will be the oldest type of sensor. It really is much easier to implement and comparatively more stable in diverse room temperature. Nonetheless its performance is going to be highly influenced by the clarity of the optical surface. Because of this, when choosing 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 your skin along with the silicon chip. Fractional treatments offers several advantages like to become a better 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 just not popular 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 can be stored from the Fingerprint Machine. It is advisable to go with a fingerprint machine which has fingerprint template twice the maximum amount of employee. With variety of fingerprint template twice the amount of employee, each employee can register a backup finger when the machine has a problem for identification.
Capacity of Log Buffer: capacity of log buffer is the most of log transactions that may be stored temporarily inside Fingerprint Machine. Time attendance transaction log is often stored for several days prior to being downloaded into database sever. Therefore, the proportions of log buffer has to be many times (usually a lot more than five times) bigger than quantity of employee.
Identification Speed: identification speed may be the average time required by fingerprint machine to recognize an individual depending on her or his fingerprint pattern. The procedure comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against a unique fingerprint database. An excellent fingerprint machine will be able to identify someone within just 1-second.
Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It might wrongly find out the fingerprint pattern. There’s two kinds of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Minute rates are the proportion of machine to grant access the impostors. Meanwhile, False Rejection Rate is the proportion of machine to reject access by authorized user. Fingerprint Machine should have low FRR and much. 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 helps as well the owner to investigate productivity of each one employee. While not all fingerprint machines include built-in reporting software, it is very important part of time attendance system. It will deliver the cause the dog owner. The quality of fingerprint machine depends on its capability to deliver reports that match the business requirements.
There are many different models, features, and capabilities of fingerprint machine you can find nowadays. Essentially the most advance and versatile fingerprint machine very can be not the most suitable for particular company’s environment. The most effective strategy is one which fits the company and technical requirements. It implies the machine will need to have appropriate technical specification that suits the physical environment and amount of users. It requires to also deliver valuable information for managing the recruiting productivity.
