Biometric Technology enables identification of person determined by intrinsic physical characteristics. There are several body parts that happen to be frequently used for biometric identification including fingerprint, face, iris, and palm. Fingerprint could be the one which most favored for identification system. Besides showing unique pattern for each individual, fingerprint also possess other attributes making it popular biometric object like very easy to capture, consistent throughout human lifespan and enable quick verification.

Today, fingerprint machine has been trusted as standard office equipments. Its usage encompasses number of purposes. It really is employed for governing the physical security access, authenticating privilege for particular business process, and in addition recording time attendance. This article mainly discusses the final issue, which would be to allow you to choose fingerprint machine as a time attendance recorder. Several features you need to consider in choosing fingerprint machine:

Sort of Sensor: sensor is a vital portion of fingerprint machine. It captures the picture of fingerprint prior to being changed into unique identification number. There are two most common kinds of sensors: optical sensor and silicon sensor.
Optical Sensor will be the oldest sort of sensor. It can be better to implement and relatively more stable in diverse 70 degrees. Nonetheless its performance will likely be highly dependent on the clarity from the optical surface. For this reason, 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 involving the skin along with the silicon chip. Fractional laser treatments offers several advantages like creating 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 isn't commonly used for public usage such as time attendance machine that'll be accessed numerous times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image which can be stored inside the Fingerprint Machine. Make sure you select a fingerprint machine which has fingerprint template at least two times the maximum amount employee. Insurance agencies variety of fingerprint template twice the quantity of employee, each employee can register a backup finger in the event the machine carries a problem for identification.
Capacity of Log Buffer: capacity of log buffer could be the maximum number of log transactions that could be stored temporarily within the Fingerprint Machine. Time attendance transaction log is usually stored stay prior to being downloaded into database sever. Therefore, the ability of log buffer should be repeatedly (usually greater than more) larger than amount of employee.
Identification Speed: identification speed will be the average time essential to fingerprint machine to recognize a person according to their fingerprint pattern. The process comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. A fantastic fingerprint machine can identify someone in less than 1-second.
Standard Error: Fingerprint machine cannot work perfectly on a regular basis. It could wrongly identify the fingerprint pattern. There are 2 kinds of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rate is the share of machine to grant connect to the impostors. Meanwhile, False Rejection Rate is the percentage of machine to reject access by authorized user. Fingerprint Machine needs to have low FRR and much. A Standard 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 also helps the master to analyze productivity of each one employee. While not all fingerprint machines have built-in reporting software, it is crucial element of time attendance system. It is going to deliver the lead to the dog owner. The grade of fingerprint machine is determined by being able to deliver reports that satisfy the business requirements.
There are various 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 choice for particular company's environment. The most effective strategy is the one that fits the company and technical requirements. It indicates your machine must have appropriate technical specification that suits the physical environment and number of users. It requires to also deliver valuable information for managing the recruiting productivity.
