  1.  Biometric Technology enables identification of human depending on intrinsic physical characteristics. There are several areas of the body that happen to be widely used for biometric identification including fingerprint, face, iris, and palm. Fingerprint will be the the one which most in-demand for identification system. Besides showing unique pattern for everybody, fingerprint also possess other attributes which render it popular biometric object for example easy to capture, consistent throughout human lifespan and give quick verification.
  2.  Today, fingerprint machine has been popular as standard office equipments. Its usage encompasses variety of purposes. It can be useful for controlling the physical security access, authenticating privilege for particular business process, and also recording time attendance. This short article mainly discusses the last issue, which would be to assist you to choose fingerprint machine as a time attendance recorder. Right here features you need to consider in choosing fingerprint machine:
  3.  Type of Sensor: sensor is an essential part of fingerprint machine. It captures the look of fingerprint prior to being converted into unique identification number. There's two most frequent forms of sensors: optical sensor and silicon sensor.
  4.  Optical Sensor could be the oldest kind of sensor. It can be simpler to implement and comparatively more stable in diverse 70 degrees. Nonetheless it is performance will likely be highly dependent on the clarity from the optical surface. For this reason, when scouting for 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.

  7.  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 several advantages like making a better fingerprint image, occupying smaller space, and requiring smaller to budget implement. However, unprotected silicon sensor won't be durable for frequent usage. Consequently, Silicon Sensor is just not frequently used for public usage like time attendance machine that is to be accessed countless times everyday.
  8.  Capacity of Fingerprint Template: capacity of fingerprint template is maximum number of fingerprint image that could be stored from the Fingerprint Machine. You should pick a fingerprint machine which has fingerprint template twice the most employee. By having amount of fingerprint template twice the volume of employee, each employee can register a backup finger in the event the machine features a problem for identification.
  9.  Capacity of Log Buffer: capacity of log buffer is the most of log transactions that could be stored temporarily in the Fingerprint Machine. Time attendance transaction log is usually stored during their visit prior to being downloaded into database sever. Therefore, the proportions of log buffer have to be many times (usually more than five times) greater than level of employee.
  10.  Identification Speed: identification speed is the average time essental to fingerprint machine to spot an individual determined by her or his fingerprint pattern. The process comprises scanning the fingerprint, searching, and comparing the fingerprint pattern against its fingerprint database. A good fingerprint machine can identify an individual within just 1-second.
  11.  Standard Error: Fingerprint machine cannot work perfectly constantly. It might wrongly know the fingerprint pattern. There are 2 types 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 Minute rates are the share of machine to reject access by authorized user. Fingerprint Machine must have low FRR and a lot. A typical quality reference for FRR is below 0.1% as well as FAR is below 0.001%.
  12.  Reporting Software: reporting software aggregates the transaction logs and reports in readable format. Miracle traffic bot also helps the dog owner to evaluate productivity of each employee. While not all fingerprint machines have built-in reporting software, it's very important component of time attendance system. It's going to provide you with the cause the owner. The quality of fingerprint machine depends upon its ability to deliver reports that meet the business requirements.
  13.  There are many different 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 best product is one which fits the company and technical requirements. It means the equipment have to have appropriate technical specification that matches the physical environment and amount of users. It must also deliver valuable information for handling the human resources productivity.
