Tips for Deciding on a Fingerprint Time Attendance System
Biometric Technology enables identification of person based on intrinsic physical characteristics. There are several areas of the body which are popular for biometric identification like fingerprint, face, iris, and palm. Fingerprint is the the one which most widely used for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes which make it popular biometric object including very easy to capture, consistent throughout human lifespan and let quick verification.
Today, fingerprint machine continues to be popular as standard office equipments. Its usage encompasses selection of purposes. It's utilized for governing the physical security access, authenticating privilege for particular business process, plus recording time attendance. This article mainly discusses the very last issue, which would be to help you to choose fingerprint machine as a time attendance recorder. Below are some features that you need to consider when scouting for fingerprint machine: 
Type of Sensor: sensor is the most important section of fingerprint machine. It captures the style of fingerprint prior to being converted into unique identification number. There are two most typical varieties of sensors: optical sensor and silicon sensor.
Optical Sensor may be the oldest form of sensor. It really is better to implement and comparatively more stable in diverse 70 degrees. Nonetheless it is performance will be highly dependent on the clarity of the optical surface. For this reason, 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 the skin and the silicon chip. Fraxel treatments offers several advantages like creating 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 isn't widely used for public usage including time attendance machine that will be accessed hundreds of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is most of fingerprint image that may be stored from the Fingerprint Machine. It is advisable to pick a fingerprint machine which has fingerprint template at least two times the maximum amount of employee. Insurance firms 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 could be the most of log transactions which can be stored temporarily inside the Fingerprint Machine. Time attendance transaction log is generally stored for several days prior to being downloaded into database sever. Therefore, the ability of log buffer have to be more than once (usually greater than 5 times) bigger level of employee.
Identification Speed: identification speed is the average time necessary for fingerprint machine to recognize somebody determined by his / her fingerprint pattern. The task comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. A great fingerprint machine are able to identify a person within just 1-second.
Standard Error: Fingerprint machine cannot work perfectly continuously. It may well wrongly identify the fingerprint pattern. There's two forms of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rate is the percentage of machine to allow connect to the impostors. Meanwhile, False Rejection Rate is the proportion of machine to reject access by authorized user. Fingerprint Machine must have as low as possible FRR and a lot. A typical 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. Quite sure can also help the dog owner to evaluate productivity of each and every employee. However, not all fingerprint machines include built-in reporting software, it is vital element of time attendance system. It's going to deliver the cause the dog owner. The grade of fingerprint machine depends upon its capability to deliver reports that match the business requirements.
There are several 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 option for particular company's environment. The very best method is the one which fits the business and technical requirements. It means the machine must have appropriate technical specification that fits the physical environment and amount of users. It has to also deliver valuable information for managing the recruiting productivity.
