Biometric Technology enables identification of human according to intrinsic physical characteristics. There are lots of areas of the body that happen to be commonly used for biometric identification including fingerprint, face, iris, and palm. Fingerprint will be the the one that most favored for identification system. Besides showing unique pattern for each person, fingerprint also possess other attributes making it popular biometric object such as very easy to capture, consistent throughout human lifespan and let quick verification.
Today, fingerprint machine has been popular as standard office equipments. Its usage encompasses various purposes. It is useful for governing the physical security access, authenticating privilege for particular business process, and in addition recording time attendance. This article mainly discusses the past issue, which would be to enable you to choose fingerprint machine being a time attendance recorder. Right here features you have to consider in choosing fingerprint machine:
Sort of Sensor: sensor is the most important section of fingerprint machine. It captures the style of fingerprint prior to being become unique identification number. There are 2 most common forms of sensors: optical sensor and silicon sensor.
Optical Sensor could be the oldest type of sensor. It’s much easier to implement and relatively more stable in diverse 70 degrees. However its performance will likely be highly determined by the clarity with the optical surface. That is why, when scouting for 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 as well as the silicon chip. Fraxel treatments offers many perks 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 just isn’t commonly used for public usage for example time attendance machine that is to be accessed hundreds of times everyday.
Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that can be stored from the Fingerprint Machine. You should pick a fingerprint machine containing fingerprint template at least two times the maximum amount of employee. With quantity of fingerprint template twice the amount of employee, each employee can register a backup finger in the event the machine has a problem for identification.
Capacity of Log Buffer: capacity of log buffer will be the maximum number of log transactions that may be stored temporarily inside the Fingerprint Machine. Time attendance transaction log is generally stored stay before being downloaded into database sever. Therefore, the proportions of log buffer have to be repeatedly (usually greater than 5 times) larger than quantity of employee.
Identification Speed: identification speed is the average time essential to fingerprint machine to distinguish somebody depending on their fingerprint pattern. The process comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its own fingerprint database. An excellent fingerprint machine should 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 2 kinds 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 Rates are the percentage of machine to reject access by authorized user. Fingerprint Machine should have to a minimum FRR and FAR. A typical quality reference for FRR is below 0.1% as well as FAR is below 0.001%.
Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Miracle traffic bot also helps the owner to evaluate productivity of every employee. But not all fingerprint machines have built-in reporting software, it is crucial component of time attendance system. It’s going to give you the result to the master. The caliber of fingerprint machine depends upon being able to deliver reports that match the business requirements.
There are various models, features, and capabilities of fingerprint machine available in the market nowadays. The most advance and versatile fingerprint machine very can be not the best choice for particular company’s environment. The top technique is one which fits the business enterprise and technical requirements. This means the equipment should have appropriate technical specification which fits the physical environment and number of users. It must also deliver valuable information for managing the hr productivity.
