Biometric Technology enables identification of person depending on intrinsic physical characteristics. There are numerous areas of the body that happen to be frequently used for biometric identification for example fingerprint, face, iris, and palm. Fingerprint may be the the one that most favored for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes which make it popular biometric object like simple to capture, consistent throughout human lifespan and let quick verification.
Today, fingerprint machine continues to be traditionally used as standard office equipments. Its usage encompasses various purposes. It is employed for governing the physical security access, authenticating privilege for particular business process, as well as recording time attendance. This post mainly discusses the last issue, which would be to allow you to choose fingerprint machine as a time attendance recorder. Here are several features you have to consider in choosing fingerprint machine:
Kind of Sensor: sensor is a vital a part of fingerprint machine. It captures the look of fingerprint before being transformed into unique identification number. There's 2 most popular types of sensors: optical sensor and silicon sensor. Optical Sensor could be the oldest type of sensor. It can be better to implement and relatively more stable in diverse room temperature. However its performance will likely be highly dependent upon the clarity from the optical surface. Because of this, in choosing fingerprint machine with optical sensor, you should think about 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. This technology offers many perks like creating a better fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor will not be durable for frequent usage. Consequently, Silicon Sensor isn't widely used for public usage such as 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 could be stored inside Fingerprint Machine. Make sure you pick a fingerprint machine that has fingerprint template at least 2 times the maximum amount employee. With quantity of fingerprint template twice the volume 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 maximum number of log transactions that may be stored temporarily within the Fingerprint Machine. Time attendance transaction log is generally stored stay before being downloaded into database sever. Therefore, the proportions of log buffer should be several times (usually greater than five times) bigger than quantity of employee. Identification Speed: identification speed will be the average time necessary for fingerprint machine to distinguish someone determined by their fingerprint pattern. The method comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. A fantastic fingerprint machine will be able to identify someone in under 1-second. Standard Error: Fingerprint machine cannot work perfectly all the time. It may wrongly get the fingerprint pattern. There's two varieties of identification error: FAR (False Acceptance Rate) and FRR (False Rejection Rate). False Acceptance Rates are the percentage of machine to grant access the impostors. Meanwhile, False Rejection Rate is the share of machine to reject access by authorized user. Fingerprint Machine needs to have as low as possible FRR and a lot. A Standard 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 also helps the property owner to analyze productivity of each and every employee. But not all fingerprint machines include built-in reporting software, it's very important portion of time attendance system. It's going to provide you with the result to the property owner. The standard of fingerprint machine depends on its ability to deliver reports that satisfy the business requirements. There are various models, features, and capabilities of fingerprint machine available for sale nowadays. Probably the most advance and versatile fingerprint machine may be not the most appropriate for particular company's environment. The very best method is the one that fits the company and technical requirements. It means the machine must have appropriate technical specification that matches the physical environment and number of users. It has to also deliver valuable information for managing the human resources productivity.
